ITEM 1.   BUSINESS

   Offshore Logistics, Inc. was incorporated in Louisiana in 1969 and its state
of incorporation was changed to Delaware in 1988. Unless the context herein
indicates otherwise, all references to the "Company" refer to Offshore
Logistics, Inc., ("OLOG") and its majority-owned entities and non-majority owned
entities. The Company's executive offices are located at 224 Rue de Jean, Post
Office Box 5-C, Lafayette, Louisiana 70505, and its telephone number is (318)
233-1221.

   The Company, through its Air Logistics subsidiaries ("Air Log") and with its
investment in Bristow Aviation Holdings Limited ("Bristow"), is a major supplier
of helicopter transportation services to the worldwide offshore oil and gas
industry.  See Note C in "Notes to Consolidated Financial Statements" for
discussion of the Company's investment in Bristow.   At March 31, 1998, Air
Log's and Bristow's operations included 379 aircraft (including 78 aircraft
operated through unconsolidated entities).

   Through a series of transactions in 1993 and 1994, the Company expanded its
operations to include production management services.  In September 1994, Grasso
Production Management, Inc. ("GPM") became a wholly-owned subsidiary of the
Company.

   See Note L in "Notes to Consolidated Financial Statements" for information on
the Company's operating revenue, operating profit and identifiable assets by
industry segment and geographical distribution for the year ended March 31,
1998, the nine month period ended March 31, 1997 and the year ended June 30,
1996.



                               FISCAL YEAR CHANGE
                                        
                                        
   On May 1, 1997, the Board of Directors approved a change in the Company's
fiscal year end from June 30 to March 31, effective for the nine month period
ended March 31, 1997.  As a result of this change in year end, this report
includes the fiscal year ended March 31, 1998, the nine month fiscal transition
period from July 1, 1996 through March 31, 1997 and the fiscal year ended June
30, 1996.


                           FORWARD LOOKING STATEMENTS
                                        

   This report contains "forward-looking statements" within the meaning of
Section 27A of the Securities Act of 1933, as amended, and Section 21E of the
Securities Exchange Act of 1934, as amended (the "Exchange Act"). All statements
included herein other than statements of historical fact are forward-looking
statements. Such forward-looking statements include, without limitation, the
statements herein regarding the timing of future events regarding the Company's
operations, the statements under "Helicopter Activities -- United States
Operations" regarding the ability of the Company to better manage its helicopter
fleet, under "Production Management Services -- Customers" and "Production
Management Services -- Competition" regarding outsourcing and cost structure and
the market for production management operations, under "General -- Union
Activities" regarding the effect of the Company's pilots electing to be
represented by a union, under "Legal Proceedings" regarding the Company's
potential liability on environmental claims, under "Management's Discussion and
Analysis of Financial Condition and Results of Operations -- General" and
"Helicopter Activities" regarding, respectively, concentration and globalization
of the helicopter industry, restructuring of the oil and gas industry and
increased levels of activity and their effects on the Company's future prospects
and under "Management's Discussion and Analysis of Financial Condition and
Results of Operations -- Liquidity and Capital Resources" regarding the
Company's anticipated future financial position and cash requirements and the
impact of Year 2000 compliance.

   Although the Company believes that the expectations reflected in such
forward-looking statements are reasonable, it can give no assurance that such
expectations will prove to be correct. Important factors that could cause actual
results to differ materially from the Company's expectations ("Cautionary
Statements") may include, but are not limited to, demand for Company services,
worldwide activity levels in oil and natural gas exploration, development and
production, fluctuations in oil and natural gas prices, unionization and the
response thereto by the Company's customers, currency fluctuations,
international political conditions and ability to achieve Year 2000 compliance.
All subsequent written and oral forward-looking statements attributable to the
Company or persons acting on its behalf are expressly qualified in their
entirety by the Cautionary Statements.

   Air Log and Bristow charter their helicopters to customers for use in
transporting personnel and time-sensitive equipment from onshore bases to
offshore drilling rigs, platforms and other installations.  The helicopter
charters are for varying periods and, in some cases, may contain provisions for
cancellation prior to completion of the contract.  Charges under these charter
agreements are generally based on either a daily or monthly fixed fee plus
additional hourly charges.  Helicopter activities are seasonal in nature and
influenced by weather conditions, length of daylight hours, and level of
offshore production, exploration, and construction activity.

   The following table sets forth the number and type of aircraft operated by
Air Log and Bristow at the end of the past three fiscal years.

   In addition to the foregoing 299 aircraft, at March 31, 1998, Air Log and
Bristow operated 2 aircraft pursuant to operating lease arrangements.  Bristow
provides engineering and administrative support to 47 aircraft operated in an
unconsolidated entity involved in military training.  Air Log and Bristow also
provide services and technical support to other unconsolidated entities that
operate 26 helicopters of various types and 5 fixed wing aircraft.

                                       2
<PAGE>
 
UNITED STATES OPERATIONS

   The United States helicopter activities are conducted primarily from
operating facilities along the Gulf of Mexico.  As of March 31, 1998, Air Log
operated 142 aircraft in that area. Air Log also operates 12 aircraft in Alaska.
Although the Company's business is primarily dependent upon activity levels in
the offshore oil and gas industry, the existence of other markets for helicopter
services distinguishes the Company's business from other segments of the oil
service industry.  Other markets for helicopters include emergency medical
transportation, agricultural and forestry support and general aviation
activities.  These other markets enable the Company to better manage its
helicopter fleet by providing both a source of additional aircraft during times
of high demand and potential purchasers for excess Company aircraft during times
of reduced demand.

UNITED KINGDOM/EUROPE OPERATIONS

   During 1997, the Company expanded its presence in the United Kingdom and
Europe through its investment in Bristow. As of March 31, 1998, 73 aircraft were
being operated by Bristow in the United Kingdom and Europe, mainly  in  the
North Sea offshore market.  These activities are primarily dependent upon
activity levels in the offshore oil and gas production, exploration and
construction industries in that area.

   Bristow also has a 33% interest in an unconsolidated entity that has a 15
year contract to provide pilot training and maintenance services to the British
military.  This entity purchased and specially modified 47 aircraft and
maintains a staff of approximately 600 employees dedicated to conducting these
training activities which began in May 1997.  In June 1998, Bristow purchased an
additional 17% interest in this entity for approximately (Pounds)1,700,000
($2,800,000).

OTHER INTERNATIONAL OPERATIONS

   Utilization of helicopters in international service is dependent on the
worldwide level of oil and gas exploration and development offshore and in
remote areas.  This, in turn, is dependent on the funds available to the major
oil companies to conduct such activities and upon the number and location of new
foreign concessions.  As of March 31, 1998, Air Log and Bristow operated 74 of
their helicopters in locations outside the United States and Europe. Air Log
operated 19 aircraft in Brazil, Colombia, Egypt and Mexico. Bristow operated 26
aircraft in Africa and 29 aircraft elsewhere throughout the world.

   In addition to its direct operations in international areas, Air Log and
Bristow have service agreements with, and equity interests in, entities that
operate 31 aircraft in Egypt and Mexico. Air Log and Bristow provide services
and technical support to these entities and, from time to time, lease aircraft
to these entities as additional support for these operations.

CUSTOMERS

   The principal customers for the Company's helicopter activities are national
and international petroleum and offshore construction companies. During 1998,
1997, and 1996, no one customer accounted for more than 10% of the Company's
consolidated operating revenues.

COMPETITION

   The helicopter transportation business is highly competitive on a worldwide
basis.  Chartering of helicopters is usually done on the basis of competitive
bidding among those having the necessary equipment and resources.  The technical
requirements of operating helicopters offshore have increased as oil and gas
activities have moved into deeper water and more sophisticated aircraft are
required to service the market. The number of small helicopter operators in the
Gulf of Mexico has declined over the past several years, as it has become
increasingly difficult to maintain an adequate shorebased infrastructure and
provide the working capital required to conduct such operations, especially when
the associated costs must be spread over a relatively small number of
helicopters. One of Air Log's competitors has substantially more helicopters in
service in the Gulf of Mexico.  The harsh conditions in the North Sea demand
larger more sophisticated equipment to conduct operations.  Bristow has two
significant competitors in the North Sea.

INDUSTRY HAZARDS AND INSURANCE

   Hazards, such as adverse weather and marine conditions, crashes, collisions
and fire are inherent in the offshore transportation industry, and may result in
losses of equipment, revenues or death of personnel.

                                       3

   Air Log and Bristow maintain Hull and Liability insurance, which generally
insures them against certain legal liabilities to others, as well as damage to
their aircraft.  It is also their policy to carry insurance for or require their
customers to provide indemnification against expropriation, war risk and
confiscation of their helicopters employed in international operations.  There
is no assurance that in the future they will be able to maintain their existing
coverage or that the premiums therefrom will not increase substantially.

GOVERNMENT REGULATION

   United States.  As a commercial operator of small aircraft, Air Log is
subject to regulations pursuant to the Federal Aviation Act of 1958, as amended,
and other statutes.  Air Log carries persons and property in its helicopters
pursuant to an Air Taxi  Certificate granted by the Federal Aviation
Administration ("FAA").

   The FAA regulates the flight operations of Air Log, and in this respect,
exercises jurisdiction over personnel, aircraft, ground facilities and certain
technical aspects of its operations.  The National Transportation Safety Board
is authorized to investigate aircraft accidents and to recommend improved safety
standards.  Air Log is also subject to the Communications Act of 1934 because of
the use of radio facilities in its operations.

   Under the Federal Aviation Act, it is unlawful to operate certain aircraft
for hire within the United States unless such aircraft are registered with the
FAA and the operator of such aircraft has been issued an operating certificate
by the FAA.  As a general rule, aircraft may be registered under the Federal
Aviation Act only if the aircraft is owned or controlled by one or more citizens
of the United States and an operating certificate may be granted only to a
citizen of the United States.  For the purposes of these requirements, a
corporation is deemed to be a citizen of the United States only if, among other
things, at least 75% of the voting interest therein is owned or controlled by
United States citizens.  In the event that persons other than United States
citizens should come to own or control more than 25% of the voting interest in
the Company, the Company has been advised that Air Log's aircraft may be subject
to deregistration under the Federal Aviation Act and loss of the privilege of
operating within the United States.  At March 31, 1998, the Company had
approximately 1,563,734 common shares held by persons with foreign addresses
representing approximately 7.2% of the 21,854,921 common shares outstanding.

   The Company's operations are subject to federal, state and local laws and
regulations controlling the discharge of materials into the environment or
otherwise relating to the protection of the environment. To date, such laws and
regulations have not had a material adverse effect on the Company's business or
financial condition. Increased public awareness and concern over the
environment, however, may result in future changes in the regulation of the oil
and gas industry, which in turn could adversely affect the Company.

   United Kingdom. As a commercial operator of aircraft, Bristow is subject to
the Licensing of Air Carriers Regulations 1992, and Regulations made under the
Civil Aviation Act 1982 and other statutes. Bristow carries persons and property
in its helicopters pursuant to an operating license issued by the Civil Aviation
Authority ("CAA").

   The CAA regulates the flight operations of Bristow, and in this respect,
exercises jurisdiction over personnel, aircraft, ground facilities and certain
technical aspects of Bristow's operations. Accident investigations are carried
out by the Accident Investigation Branch of the Department of the Environment,
Transport and the Regions. The CAA often imposes improved safety standards on
the basis of a report of the Inspector.

   Under the Licensing of Air Carriers Regulations 1992, it is unlawful to
operate certain aircraft for hire within the United Kingdom unless such aircraft
are approved by the CAA.  The holder of an operating license must meet the
ownership and control requirements of Council Regulation 2407/92 (i.e. the
entity that operates under the license must be owned directly or through
majority ownership by United Kingdom or European Economic Area nationals and
must at all times be effectively controlled by them).

   Bristow's operations are subject to local laws and regulations controlling
the discharge of materials into the environment or otherwise relating to the
protection of the environment. To date, such laws and regulations have not had a
material adverse effect on Bristow's business or financial condition. Increased
public awareness and concern over the environment, however, may result in future
changes in the regulation of the oil and gas industry, which may in turn have an
adverse affect on the Company.

   International. Operations other than in the United States and the United
Kingdom are subject to local governmental regulations and to uncertainties of
economic and political conditions in those areas.  Because of the impact of
local laws, these operations are conducted primarily through entities (including
joint ventures) in which local citizens own interests and Air Log or Bristow
holds only a minority interest, or pursuant to arrangements under which the
Company operates assets or conducts operations under contracts with local
entities.  There can be no assurance that 

                                       4
<PAGE>
 
there will not be changes in local laws, regulations or administrative
requirements, or the interpretation thereof, any of which could have a material
adverse effect on the business or financial condition of the Company or on its
ability to continue operations in certain regions.

CURRENCY FLUCTUATIONS

   Bristow's revenues and expenses are reported in British Pounds Sterling
("pound"). For the year ended March 31, 1998, 62% of consolidated operating
revenues were translated from pounds into the United States Dollar.  In
addition, a portion of Bristow's revenues are denominated in other currencies
(including Australian Dollars, French Francs, Nigerian Naira and Trinidad and
Tobago Dollars) to cover expenses in the areas in which such expenses are
incurred. To the extent operating revenues are denominated in the same currency
as operating expenses, the Company can reduce its vulnerability to exchange rate
fluctuations. Because the Company maintains its financial statements in United
States Dollars, it is vulnerable to fluctuations in the exchange rate between
the pound and the United States Dollar.


                         PRODUCTION MANAGEMENT SERVICES
                                        
                                        
   The Company's wholly owned subsidiary, GPM is the leading independent
contract operator of oil and gas production facilities in the Gulf of Mexico. In
addition, GPM also provides services for certain onshore facilities. In
providing these services, GPM operates oil and gas production facilities for
major and smaller independent oil and gas companies.  Typical project
assignments may involve full or limited management of operations of oil and gas
production facilities located offshore, particularly in the Gulf of Mexico.  The
work involves placing experienced crews, employed by GPM, to operate the
facilities and provide all necessary services and products for the offshore
operations.  When servicing offshore oil and gas production facilities, GPM's
employees normally live on the facility for a seven day rotation.  GPM's
services include furnishing personnel, engineering, production operating
services, paramedic  services and the provision of boat and helicopter
transportation of personnel and supplies between onshore bases and offshore
facilities.  GPM also handles regulatory and production reporting for certain of
its customers.

OPERATIONS

   GPM's production management services are conducted primarily from production
facilities in the Gulf of Mexico.  As of March 31, 1998, GPM managed or had
personnel assigned to 180 production facilities in the Gulf of Mexico.  Although
GPM's business is primarily dependent upon activity levels in the offshore oil
and gas industry, 90% of GPM's production management costs consist of labor and
contracted transportation services.  This enables GPM to scale down operations
rapidly should market conditions change.  Because of this ability to react to
market conditions, management believes the production management segment of the
oil service industry is less affected by downturns in offshore oil and gas
activities.

CUSTOMERS

   GPM's customers are primarily major and small independent oil and gas
companies that own oil and gas production facilities in the Gulf of Mexico.
These companies are increasingly inclined to out-source services provided by
companies such as GPM which are able to operate more efficiently and with a
lower cost structure.  This allows the customers to focus their efforts on their
core activities, which is the exploration and production of oil and gas.  During
1998, 1997 and 1996, no single GPM customer accounted for more than 10% of the
Company's consolidated operating revenues.

COMPETITION

   GPM's business is highly competitive.  There are a number of competitors that
are smaller than GPM but maintain a Gulf-wide presence.  In addition, there are
many smaller operators that compete on a local basis or for single projects or
jobs.  Management of the Company anticipates that the market for oil and gas
production management operations will continue to increase over the next few
years as oil and gas producing companies continue to reduce the size of field
personnel and further utilize outside contractors as efforts to reduce their
operating costs continue.  Typically, GPM will be requested to bid on one or
more production facilities owned by an oil and gas producer.  The two key
elements in the pricing of the bid are personnel and transportation costs.  In
addition to price,  an additional consideration is the quality of personnel,
training programs, safety record and stability of the operator since this can
greatly affect the revenue flow to the producer and reduce the risk of possible
damage to the production facility.  There are no assurances that an increase in
the market for production management will occur.

                                       5
<PAGE>
 
INDUSTRY HAZARDS AND INSURANCE

   GPM's operations are subject to the normal risks associated with  working on
oil and gas production facilities.  These risks could result in damage to or
loss of property and injury to or death of personnel.  GPM carries normal
business insurance including general liability, worker's compensation,
automobile liability and property and casualty insurance coverages.

GOVERNMENT REGULATION

   The Mineral Management Service ("MMS") regulates the production  operations
of GPM's customers and, in this respect, exercises jurisdiction over personnel,
production facilities and certain technical aspects of GPM's operations.

   GPM's operations are subject to federal, state and local laws and regulations
controlling the discharge of materials into the environment or otherwise
relating to the protection of the environment. To date, such laws and
regulations have not had a material adverse effect on GPM's business or
financial condition.  Increased public awareness and concern over the
environment, however, may result in future changes in the regulation of the oil
and gas industry, which in turn could adversely affect the Company.


                                    GENERAL
                                        

EMPLOYEES

          As of March 31, 1998 Air Log, Bristow and GPM employed 725, 1,821 and
594 employees worldwide, respectively.  The Company's corporate staff consisted
of 25 employees.

UNION ACTIVITIES

   On August 6, 1997, the domestic pilots at the Company voted to become members
of the Office and Professional Employees International Union ("OPEIU").  The
Company commenced contract negotiations with the OPEIU on April 1, 1998 and it
is not certain how long this process may take.  During the fiscal year ended
March 31, 1998, $98.4 million of operating revenues were from the Company's
domestic helicopter operations. In January 1998, the OPEIU petitioned the
National Mediation Board ("NMB") to organize the Company's domestic mechanics
and ground support personnel.  Certain objections to this petition were filed
and the  NMB dismissed the OPEIU application on May 12, 1998.  Under the Federal
labor law rules, the union is prohibited from petitioning the NMB for one-year
from date of dismissal.  The Company does not believe that the result of these
organizing efforts will place it at a competitive disadvantage with its
competitors as management believes that pay scales and work rules will continue
to be similar throughout the industry.

ITEM 2.   PROPERTIES

   See "Business -- Helicopter Activities" for a discussion of the number and

ITEM 3.   LEGAL PROCEEDINGS

   In January 1989, the Company received notice from the United States
Environmental Protection Agency ("EPA") that it is a potentially responsible
party ("PRP") for clean up and other response costs at the Sheridan Disposal
Services Superfund Site in Waller County, Texas.  The Company is among
approximately 160 PRPs identified with respect to the site. The EPA has
estimated that the cost of remedial activities at the site will be approximately
$30 million.  In August 1989, the Company received a similar notice with respect
to the Gulf Coast Vacuum Services Site, which is near Abbeville, Louisiana.  The
Company is among over 300 PRPs identified with respect to this site.  The EPA
alleged that the Company is a generator or transporter of hazardous substances
found at the two sites.  In February 1991, the Company received a request for
information from the EPA relating to the Western Sand and Gravel Superfund Site
in Rhode Island, as to which the Company had been named a PRP after an earlier
request for information from the EPA issued in 1983 - 1984.  During 1997, the
Company executed a consent decree with the EPA and settlement documents with the
Performing Parties with respect to the Company's  previous exposure at the D.L.
Mudd site.  Costs incurred were nominal.

   Based on presently available information, the Company believes that it
generated only a small portion, if any, of the substances found at the above
described sites.  In addition, many of the other PRPs at all of the
aforementioned sites are large companies with substantial resources.  As a
result, the Company believes that its potential liability for clean up and other
response costs in connection with these sites is not likely to have a material
adverse effect on the Company's business or financial condition.

   In addition to notification of PRP responsibility, the EPA notices to the
Company also contained information requests regarding the Company's connection
with the various sites.  The responses to the information requests were due in
early March 1989 for the Sheridan site and in early September 1989 for the
Louisiana site.  Through oversight, the Company did not respond to the requests
until April and May 1990.  The EPA is authorized to seek civil penalties for
failure to respond to its information requests in a timely manner in an amount
up to a maximum of $25,000 per day for each day of continued non-compliance;
however, to date, no such penalties have been sought.  While it is not possible
to predict whether any civil penalties might be assessed against the Company for
the delays in responding to the EPA requests, the Company believes the amount of
such penalties, if any, will not have a material adverse effect on its business
or financial condition.

   The Company is not a party to any other litigation, which, in the opinion of
management, will have a material adverse effect on the Company's business or
financial condition.

ITEM 7.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS

GENERAL

   The level of worldwide offshore oil and gas exploration and production
activity has traditionally influenced demand for the Company's services.  The
Company expanded its aviation services and related operations through its
investment in Bristow that was completed in December 1996.  The Company's
investment in Bristow (see Note C in the "Notes to the Consolidated Financial
Statements" for a complete discussion of this investment) was influenced by its
belief that the globalization of helicopter operators has begun with the recent
acquisitions and consolidations completed by two of its major international
competitors.  The Company believes that this trend will continue and accelerate
as helicopter operators seek to broaden their exposure to international markets
in order to better serve their customers and increase their access and influence
with financial markets, insurance markets and other suppliers.  The Company also
believes that these combinations and alliances will allow greater development of
"in-house core expertise" in dealing with manufacturers and suppliers to reduce
direct operating costs, enhance and promote flight safety, improve efficiencies
to be more competitive in the new global marketplace and provide a more fertile
environment for future investment and growth opportunities.  The combined
helicopter activities of Air Log and Bristow result in an operating fleet of 379
aircraft servicing the principal oil and gas markets of the world.

   GPM's services include furnishing personnel, engineering, production
operating services, paramedic services and the provision of boat and helicopter
transportation of personnel and supplies between onshore bases and offshore
facilities. The Company's investment in GPM was influenced by its belief that a
restructuring in the United States oil and gas industry is taking place,
resulting in part from the instability of oil and gas prices over the last
several years. As part of this restructuring, major oil companies have been
reducing the size of their field organizations and concentrating more on larger
projects such as deepwater Gulf of Mexico and offshore projects in various
international areas. Management believes that this restructuring is creating
opportunities, first, for smaller, independent oil companies as the major oil
companies have been selling properties in the Gulf of Mexico, second, for
companies providing production management services to smaller, independent oil
companies, which frequently lack the personnel to operate these properties and
finally for major oil companies as they transfer their focus and technical
personnel to new and larger projects. Although there can be no assurances,
management believes that, through GPM, the Company has the opportunity to take
advantage of increases in the market for oil and gas production management
services that may occur over the next few years. Management also believes that
the addition of the production management services business may permit the
Company, by providing helicopter services through the production management
services business to smaller, independent companies, to enhance its market share
for its helicopter transportation services in the very competitive and rapidly
changing Gulf of Mexico environment.

HELICOPTER ACTIVITIES

   Air Log and Bristow conduct helicopter activities principally in the Gulf of
Mexico and the North Sea, respectively, where they provide support to the
production, exploration and construction activities of oil and gas companies.
Air Log also charters helicopters to governmental entities involved in
regulating offshore oil and gas operations in the Gulf of Mexico.  Bristow also
provides search and rescue work for the British Coast Guard.  Air Log's Alaskan
activity is primarily related to providing helicopter services to the Alyeska
Pipeline.  Air Log has service agreements with, and equity interests in,
entities that operate aircraft in Egypt and Mexico ("unconsolidated entities").
Air Log and Bristow also operate in various other international areas (including
Australia, Brazil, Brunei, China, Colombia, the Falklands, Mexico, Nigeria and
Trinidad).  These international operations are subject to local governmental
regulations and to uncertainties of economic and political conditions in those
areas.

   The following table sets forth certain information regarding aircraft
operated by Air Log, Bristow and unconsolidated entities data related to
helicopter activities.

</TABLE>

(1)  Includes data for Bristow after the effective date of the investment on
December 19, 1996.

 Helicopter activities reflected exceptional increases during 1998 and 1997
fiscal periods compared to similar periods in prior years primarily as the
result of the Company's investment in Bristow and improved market conditions in
the Gulf of Mexico.

 Activity levels in the Gulf of Mexico were strong during fiscal 1998 and 1997.
Increases in helicopter rates in fiscal 1998 and 1997 had a positive impact on
operating revenues in the Gulf of Mexico during 1998 and 1997.  Gulf of Mexico
flight hours and operating revenues for 1998 increased 22% and 24%,
respectively, over the similar twelve month period in 1997.  Gulf of Mexico
flight hours and operating revenues for the nine months ended March 31, 1997
increased 5% and 17%, respectively, over the similar nine month period in 1996.
Gulf of Mexico operating income increased $3.9 million for 1998, a 25% increase
over the similar period in 1997.  Gulf of Mexico operating  income increased
$5.2 million for the nine months ended March 31, 1997, a 68% increase over the
similar nine month period in 1996.  Operations in Alaska were relatively
unchanged from the prior year.

   Bristow's flight hours were 95,987 and 25,683 for the year ended March 31,
1998 and for the period from investment (December 19, 1996) to March 31, 1997,
respectively.  Operating revenues were $264.6 million and $68.7 million for the
year ended March 31, 1998 and for the period from investment to March 31, 1997,
respectively.  Operating income and gross margin percentages attributable to
Bristow were $28.2 million and 10.7% for the year ended to March 31, 1998.
Gross margin percentages for Bristow are lower than Air Log's, primarily due to
different market environments, size of equipment and the cost to operate that
equipment.  As a result the consolidated gross margin from helicopter activities
for the 1998 fiscal year was lower than the prior year.  In March 1998, Bristow
was awarded a new contract with Shell UK Exploration and Production that is
considered one of the largest helicopter operating contracts in the world
projected to generate (Pounds)225 million ($370 million) over a seven year
period.

    International flight activity from Air Log continued to improve during the
year ended March 31, 1998 and the nine months ended March 31, 1997.
International flight hours and operating revenues from Air Log for 1998
increased over 4.3% and 10.7%, respectively, from the similar twelve month
period in 1997.  Flight hours and operating revenues increased over 30% in 1997
from the similar nine month period in 1996.  International operating income
increased $.9 million in 1998, a 15% increase over the similar period in 1997
and increased $1.0 million in 1997, a 27% increase over the similar nine month
period in 1996.

   The high level of activity in the Gulf of Mexico enabled the Company to
obtain rate increases in the first and third quarters of fiscal 1998 on most
aircraft operating in that area.  Subsequent to March 31, 1998, the industry
experienced a continued decline in oil commodity prices.  If this decline
continues or if commodity prices remain at historically low levels for an
extended period, management would expect a reduction in flight activity and
revenues from the various operating areas.  The impact on the Company's
operations will depend on the extent and the duration of these commodity price
reductions and the view that the Company's customers take as to viability of
their individual projects.

PRODUCTION MANAGEMENT SERVICES

   GPM's production management activities and results also experienced
significant improvements in 1998 with increases of 39% in revenues and 180% in
operating income over the same period from the prior year.  Gross margins were
7.2% for the year ended March 31, 1998, up from 3.2% from the same period in
1997.  Operating revenues were $42.8 million, $23.5 million  and $31.2 million
for the year ended March 31, 1998, the nine months ended March 31, 1997 and the
year ended June 30, 1996, respectively.  Operating expenses for GPM were $39.8
million, $22.3 million and $31.4 million, respectively for those periods.  GPM
operating income was $3.1 million, $1.2 million and $(0.2) million for the 1998,
1997 and 1996 fiscal periods, respectively.

LIQUIDITY AND CAPITAL RESOURCES

   Cash and cash equivalents were $56.1 million as of March 31, 1998, a $26.2
million increase from March 31, 1997.  Working capital as of March 31, 1998 was
$122.6 million, a $65.1 million increase from March 31, 1997.   Total debt was
$260.3 million as of March 31, 1998.

   Cash flows provided by operating activities were $68.9 million, $16.0 million
and $22.8 million in 1998, 1997 and 1996, respectively.  Cash flows provided by
operating activity increased to $68.9 million from $16.0 million primarily due
to improved market conditions in Gulf of Mexico and having twelve months of
Bristow operations in 1998 compared to approximately three months in 1997.
During 1997, as a result of the growth in helicopter activities, the Company
experienced a $16.7 million increase in accounts receivables.

   Cash flows used in investing activities were $54.2 million, $141.2 million
and $12.3 million for 1998, 1997 and 1996, respectively.

   During 1998, the Company acquired five aircraft (including four AS332L-Super
Pumas, which had previously been leased by Bristow under short-term operating
leases) for $32.3 million.  The Company used existing cash and incurred an
additional $20.0 million of 7.9% fixed rate financing, that amortizes over five
years, to complete this transaction.  In addition to the financed aircraft, the
Company used existing cash to purchase 13 Bell 407's, four Sikorsky S76's and
one 214ST in 1998.

   During 1997, the Company utilized $155.5 million for the investment in
Bristow, including the issuance of the 6% Notes.  Capital expenditures during
1997 of  $10.1 million included three new Bell 407's, one used Sikorsky S-76,
three used Boelkow 105's, and one fixed wing.

   Capital expenditures during 1996 of  $12.5 million included two new Bell
206L-IV's, four used Boelkow 105's and seven Sikorsky S-76's previously under an
operating lease agreement.

   Cash flows provided by (used in) financing activities were $10.7 million,
$98.1 million and  $(1.4) million in 1998, 1997 and 1996, respectively.   In
October 1997, the Company repaid (Pounds)11.6 million ($18.7 million) of Bristow
debt with its existing cash.  In January 1998, the Company issued $100 million
of 7 7/8% Senior Notes due 2008 discounted to yield 7.915%, which resulted in
net proceeds to the Company of $97.2 million.  The proceeds were used to repay
certain indebtness of Bristow of (Pounds)40.7 million ($66.6 million) and to
replace general corporate funds used to repay certain indebtness of Bristow in
October 1997.  The Company received $88.4 million from the issuance of the 6%
Notes during 1997.  Financing activities during 1996 were primarily for the
repayment of debt.

   As of March 31, 1998, Bristow had a (Pounds)15 million ($24 million)
revolving credit facility with a syndicate of United Kingdom banks that matures
on December 31, 2000.  Bristow had nothing drawn under this facility as of March
31, 1998.

   As of March 31, 1998, OLOG had a $20 million unsecured working capital line
of credit with a bank that expires on September 30, 1999.  Management believes
that normal operations and other available financing, will provide sufficient
working capital and cash flow to meet debt service in the foreseeable future.

   The effective income tax rates from continuing operations were 30%, 30% and
29% for 1998, 1997 and 1996, respectively.  The variance between the Federal
statutory rate and the effective rate for these periods is due primarily to non-
taxable foreign source income and foreign tax credits available to reduce
domestic taxable income.

   The Company has received notices from the EPA that it is one of approximately
160 PRPs at one Superfund site in Texas, one of over 300 PRPs at a site in
Louisiana and a PRP at one site in Rhode Island.  The Company believes, based on
presently available information, that its potential liability for clean up and
other response costs in connection with these sites is not likely to have a
material adverse effect on the Company's business or financial condition.  See
Item 3 -- "Legal Proceedings" for additional information regarding EPA notices.

OTHER MATTERS

   During 1998, the Company developed a plan to replace or modify its primary
information systems to be Year 2000 compliant by the third quarter of 1999.  The
Company does not expect the costs associated with modifying the current systems
to be material to its financial condition or results of operations.  The Company
has not incurred significant costs related to Year 2000 compliance prior to
March 31, 1998 other than internal costs to evaluate and/or modify certain of
its primary systems.  The Company expects to incur approximately $500,000 during
its 1999 fiscal year replacing certain of its primary systems.  The Company does
not anticipate any significant disruption of its operation as a result of any
failure by the Company to be in compliance.

   The Company is in the process of evaluating its Year 2000 exposure on non-
critical computer systems and Year 2000 compliance of its suppliers and
customers.  In the event that any of the Company's significant suppliers or
customers fail to achieve Year 2000 compliance, the Company does not believe its
business or operations would be adversely affected.

   During fiscal 1998, and subsequent thereto, the Financial Accounting
Standards Board ("FASB") issued SFAS No. 130, "Reporting Comprehensive Income",
SFAS No. 131, "Disclosures about Segments of an Enterprise and Related
Information", SFAS No. 132, "Employer's Disclosures about Pension and Other
Postretirement Benefits" and SFAS No. 133 "Accounting for Derivative Instruments
and Hedging Activities".  These pronouncements will be adopted during the
Company's fiscal year ending March 31, 1999.  Management believes the adoption
of these pronouncements will not have a material impact on the consolidated
financial statements.

To the Stockholders of Offshore Logistics, Inc.:

   We have audited the accompanying consolidated balance sheets of Offshore
Logistics, Inc. (a Delaware corporation) and subsidiaries as of  March 31, 1998

stockholders' investment and cash flows for the twelve months ended March 31,
1998, the nine month period ended March 31, 1997 and the twelve months ended
June 30, 1996. These financial statements are the responsibility of the
Company's management.  Our responsibility is to express an opinion on these
financial statements based on our audits.

   We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

   In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Offshore Logistics, Inc. and
subsidiaries as of March 31, 1998 and March 31, 1997, and the results of their
operations and their cash flows for the twelve months ended March 31, 1998, the
nine month period ended March 31, 1997 and  the twelve months ended June 30,
1996 in conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                        

A -- OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES


   Nature of Operations -- The Company's most significant area of operation is
supplying helicopter transportation services to the worldwide offshore oil and
gas industry.  The Company also provides production personnel and medical
support services to the worldwide oil and gas industry.

   Basis of Presentation -- The consolidated financial statements include the
accounts of Offshore Logistics, Inc., a Delaware corporation ("OLOG") and its
majority owned entities and non-majority owned entities including Bristow
Aviation Holdings Limited ("Bristow"), collectively referred to as "the
Company", after elimination of all significant intercompany accounts and
transactions.  Investments in 50% or less owned affiliates over which the
Company has the ability to exercise significant influence are accounted for
using the equity method.  Investments in which the Company does not exercise
significant influence are accounted for  under the cost method.

   Use of Estimates -- The preparation of financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosures of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.

   Cash and Cash Equivalents -- The Company's cash equivalents includes funds
invested in highly liquid debt instruments with original maturities of 90 days
or less.

   Accounts Receivable -- Trade and other receivables are stated at net
realizable value and the allowance for uncollectible accounts was $850,000 and
$1,449,000 at March 31, 1998 and March 31, 1997, respectively. The Company
grants short-term credit to its customers, primarily major and independent oil
and gas companies.

   Inventories -- Inventories are stated at the lower of average cost or market
and consist primarily of spare parts.  The valuation reserve related to obsolete
and excess inventory was $4,049,000 and  $4,074,000 at March 31, 1998 and March
31, 1997.  There were no related charges to operations in 1998, 1997, or 1996.

   Other Assets -- In 1998, $18,282,000 of goodwill, net of accumulated
amortization of $4,001,000, was included in other assets.  Goodwill is amortized
using the straight-line method over a period of 20 years.  Goodwill is
recognized for the excess of the purchase price over the value of the
identifiable net assets.  Realization of goodwill is periodically assessed by
management based on the expected future profitability and  undiscounted future
cash flows of acquired companies and their contribution to the overall
operations of the Company.

   Also included in other assets is restricted cash of (Pounds)4.8 million ($8.0
million) and debt issuance costs of $5.4 million, being amortized over the life
of the related debt.

   Depreciation and Amortization -- Depreciation and amortization are provided
on the straight-line method over the estimated useful lives of the assets.
Estimated residual value used in calculating depreciation of aircraft ranges
from 30% to 50% of cost.

   Maintenance and repairs are expensed as incurred; betterments and
improvements are capitalized.  The costs and related accumulated depreciation of
assets sold or otherwise disposed of are removed from the accounts and resultant
gains or losses included in income.

   Income Taxes -- Income taxes are accounted for in accordance with the
provisions of the Statement of Financial Accounting Standards ("SFAS")  No. 109,
"Accounting for Income Taxes".  Under this statement, deferred income taxes are
provided for by the asset and liability method.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
                                        

   Foreign Currency Translation -- Bristow maintains their accounting records in
their local currency (British Pounds Sterling).  The currencies are converted to
United States Dollars with the effect of the foreign currency translation
reflected as a component of shareholders' investment in accordance with SFAS No.
52, "Foreign Currency Translation."   Foreign currency transaction gains or
losses are credited or charged to income, and such amounts are insignificant for
the periods presented.

   Derivative Financial Instruments -- The Company enters into forward exchange
contracts from time to time to hedge known transactional exposures denominated
in currencies other than the functional currency of the business. Foreign
currency positions mature at the anticipated currency requirement date and
rarely exceed three months.  The purpose of the Company's foreign currency
hedging activities is to protect the Company from the risk that foreign currency
outflows resulting from payments for services and parts to foreign suppliers
will be adversely affected by changes in exchange rates.

   Financial instruments are designated as a hedge at inception where there is a
direct relationship to the price risk associated with the service and parts.
Hedges of anticipated transactions are accounted for under the deferral method
with gains and losses recognized in revenues when the hedged transaction occurs.
If the direct relationship to price risk ceases to exist, the difference in the
carrying value and fair value of a forward contract is recognized as a gain or
loss in revenues in the period the relationship ceases to exist.

   The Company uses interest rate swaps to manage its interest rate exposure.
Revenues or expenses on interest rate swaps are recognized over the lives of the
agreements as adjustments to interest expense of the liability being hedged.
Any interest rate swap not qualifying for deferred accounting is recorded at
fair value.

   Stock Compensation -- On July 1, 1996, the Company elected to continue to use
the intrinsic value method of accounting for stock-based compensation prescribed
by Accounting Principles Board ("APB") Opinion No. 25 and, accordingly, adopted
the disclosure provisions of SFAS No. 123, "Accounting for Stock-Based
Compensation."

   Fiscal-Year Change -- On May 1, 1997, the Board of Directors approved a
change in the Company's fiscal year end from June 30 to March 31, effective for
the nine month period ended March 31, 1997.  As a result of this change in year
end, these financial statements include the fiscal year ended March 31, 1998,
the nine month fiscal transition period from July 1, 1996 through March 31, 1997
and the fiscal year ended June 30, 1996.

   Effect of Recent Accounting Changes -- During fiscal 1998, the Financial
Accounting Standards Board ("FASB") issued SFAS No. 130, "Reporting
Comprehensive Income", SFAS No. 131, "Disclosures about Segments of an
Enterprise and Related Information" and SFAS No. 132, "Employer's Disclosures
about Pension and Other Postretirement Benefits".  These pronouncements will be
adopted during the Company's fiscal year ending March 31, 1999.  Management
believes the adoption of these pronouncements will not have a material impact on
the consolidated financial statements.

</TABLE>

   On January 27, 1998, the Company issued $100 million aggregate principal
amount of 7 7/8% Senior Notes ("Senior Notes") due 2008 discounted to yield
7.915%.  Proceeds of $97.2 million, after debt issuance costs of $2.8 million,
were used to repay approximately (Pounds)40.7 million ($66.6 million) of Bristow
debt and to replace general corporate funds used to repay certain indebtness of
Bristow in October 1997.  The weighted average of the stated rates of interest
on the indebtedness retired was 16.6%, but had been adjusted to 8.5% as a result
of purchase accounting for the Company's investment in Bristow.  The Senior
Notes are guaranteed by certain of the Company's subsidiaries (see Note N).

   On December 17, 1996, the Company issued $98 million of 6% Convertible
Subordinated Notes  ("6% Notes") due 2003.  The 6% Notes are convertible at any
time into the Company's Common Stock at a conversion price of $22.86 per share
(equivalent to a conversion rate of approximately 43.74 shares per $1,000
principal amount of 6% Notes).  The 6% Notes are redeemable at the option of the
Company beginning December 1999.  The Company issued $7.5 million of the 6%
Notes to Caledonia (See Note C) in conjunction with the investment in Bristow.
Proceeds of $88.4 million, after debt issuance costs of $2.1 million, were also
used to finance the investment in Bristow.

   Bristow renewed a term loan with a syndicate of United Kingdom banks on
January 26, 1998, that is repayable in semi-annual installments varying from
$1.7 to $5.0 million ((Pounds)1.0 to (Pounds)3.0 million) through December 31,
2002.  The term loan bears interest at 0.8% above LIBOR rates.  The average
interest rate for the term loan during the period from renewal to March 31, 1998
was 8.425%.  The term loan is guaranteed by certain United Kingdom subsidiaries
of Bristow and is secured by a negative pledge on all Bristow assets.  The
Company entered into an interest rate swap agreement to reduce the impact of
change in interest rates on this floating rate long-term debt.  At March 31,
1998, the outstanding notional amount was (Pounds)36.5 million ($61.1 million).
The agreement matures on December 31, 2001.  The market value of the notional
amount in excess of the outstanding principal amount of the term loan was not
material.

   In May 1997, the Company acquired five aircraft (including four AS332L Super
Pumas, which had previously been leased by Bristow under short-term operating
leases) for $32.3 million.  The Company used existing cash and incurred an
additional $20.0 million of 7.9% fixed rate financing, that amortizes over five
years, to complete this transaction.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

 
   Obligations under capital  leases bear interest at various rates and require
quarterly payments.  The leases are secured by the aircraft and the guarantee of
Bristow.

   Bristow has a revolving credit facility, with the same syndicate of United
Kingdom banks, as with the term loan, which matures December 31, 2000, and is
available for working capital requirements and general corporate purposes.
Availability under the revolving credit facility is subject to certain borrowing
base limitations based on the value of qualifying helicopters.  All advances
under the revolving credit facility bear interest at 0.6% above one, three, or
six month LIBOR rates.  The revolving credit facility is guaranteed by certain
United Kingdom subsidiaries of Bristow and is secured by helicopter mortgages
and a negative pledge of all Bristow assets.  The availability under the
revolving credit facility is (Pounds)15 million ($24 million).  There were no
borrowings under this revolving credit facility as of March 31, 1998.

   As of March 31, 1998, the Company had a $20 million unsecured line of credit
with a U.S. bank that expires on September 30, 1999.  There were no borrowings
under this line as of March 31, 1998.  The rate of interest payable under the
line of credit is, at the Company's option, prime rate or LIBOR rate plus 1.25%.
The agreement requires the Company to pay a quarterly commitment fee at an
annual rate of .25% on the average unused portion of the line.

   Aggregate annual maturities for all long-term debt, including the capitalized
lease, for the next five years are as follows: 1999 -- $8,693,000; 2000 --
$9,813,000; 2001 -- $11,620,000; 2002 -- $15,691,000; and 2003 -- $16,435,000.

   Interest paid during the year was $23,381,000, $3,620,000 and  $300,000 for
1998, 1997, and 1996, respectively.

   The estimated fair value of the Company's total debt at March 31, 1998 was
$269.3 million based on quoted market prices for the publicly listed 6% Notes
and the Senior Notes and the current rates offered to the Company on other
outstanding obligations.  Total debt at March 31, 1997 approximates the fair
value of the debt.


C -- INVESTMENT IN  BRISTOW

   On December 19, 1996, OLOG acquired 49% of the common stock and a significant
amount of Bristow subordinated debt as detailed below.  Bristow is incorporated
in England and holds all of the outstanding shares in Bristow Helicopter Group
Limited ("BHGL").  Bristow provides helicopter services to the North Sea oil and
gas industry.  Services consist of short and long range crew change flights,
offshore-based and inter-platform shuttle operations and search and rescue
missions.  Bristow also operates aircraft in Australia, Brunei, Cambodia, China,
Nigeria, South America and Vietnam among others.

   Bristow is organized with three different classes of ordinary shares (common
stock) having disproportionate voting rights.  The Company, Caledonia
Investments plc and its subsidiary, Caledonia Industrial & Services Limited
(collectively, "Caledonia") and a Norwegian investor  (the "E.U. Investor"), own
49%, 49% and 2%, respectively, of Bristow's total outstanding ordinary shares.

   The Company paid (Pounds)80.2 million (approximately $132 million) in cash
(funded from existing cash balances and the proceeds of the 6% Notes), issued
$7.5 million of the 6% Notes to Caledonia and issued 1,374,389 shares of common
stock on December 19, 1996.  In addition, the Company acquired (Pounds)5.0
million ($8.4 million) principal amount of BHGL's subordinated debt for cash of
approximately (Pounds)5.4 million ($8.9 million) including accrued interest.
Caledonia received 1,300,000 shares of the common stock and BHGL's management
received 74,389 shares.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
                                        


   In addition to its ownership of 49% of Bristow's outstanding ordinary shares
and (Pounds)5.0 million principal amount of Bristow's subordinated debt, the
Company acquired (Pounds)91.0 million (approximately $150 million) principal
amount of subordinated unsecured loan stock (debt) of Bristow bearing interest
at an annual rate of 13.5% and payable semi-annually.  Bristow has the right to
defer payment of interest on such debt until January 31, 2002.  Any such
deferred interest would also accrue interest at an annual rate of 13.5%.

   The Company, Caledonia, the E.U. Investor and Bristow entered into a
shareholders' agreement respecting, among other things, the composition of the
board of directors of Bristow. On matters coming before Bristow's board,
Caledonia's appointees have a total of five votes and the four other directors
have one vote each.  So long as Caledonia has a significant interest in the
shares of Common Stock issued to it pursuant to the transaction or maintains its
voting control of Bristow, Caledonia will have the right to nominate two persons
to the board of directors of the Company and to replace any such directors so
nominated.

   Caledonia, the Company and the E.U. Investor also entered into a Put/Call
Agreement whereunder, upon giving specified prior notice, the Company has the
right to buy all the Bristow shares held by Caledonia and the E.U. Investor,
who, in turn, each has the right to sell such shares to the Company.  Under
current United Kingdom law, the Company would be required, in order for Bristow
to retain its operating license, to find a qualified European investor to own
any Bristow shares it has the right to acquire under the Put/Call Agreement. Any
put or call of the Bristow shares will be subject to the approval of the Civil
Aviation Authority ("CAA").  Caledonia will receive management fees from Bristow
that will be payable semi-annually in advance ranging from (Pounds)500,000 to
(Pounds)900,000 annually for the next six years.

   The investment was accounted for by the purchase method of accounting under
Accounting Principals Board Opinion No. 16, as amended, and accordingly, the
results of operations of Bristow for the period from December 19, 1996 forward
are included in the accompanying consolidated financial statements.  The total
consideration has been allocated to Bristow's assets and liabilities based on
the estimated fair market value as of December 19, 1996.

   The following unaudited pro forma financial information for the Company gives
effect to the Bristow investment as if it had occurred on July 1, 1995.  These
pro forma results have been prepared for comparative purposes only and do not
purport to be indicative of the results of operations which actually would have
resulted had the acquisitions occurred on the date indicated, or which may
result in the future.  The pro forma results follow (in thousands, except per

D -- INVESTMENTS IN UNCONSOLIDATED ENTITIES

   The Company has two principal unconsolidated entities that are accounted for
on the cost method as the Company is unable to exert significant influence over
the operations.

   The Company has a 49% investment in Hemisco Helicopters International, Inc.
("HHII") and related venture companies.  The Company's investment in HHII was
$2,637,000 at March 31, 1998 and March 31, 1997.  In the following unaudited
table, HHII represents $5,147,000 and $3,492,000 of the assets and $3,464,000
and $2,230,000 of the equity for March 31, 1998 and March 31, 1997,
respectively.  HHII also represents $14,284,000; $9,806,000 and $10,727,000 of
revenues and $4,002,000;  $2,702,000 and $1,834,000 of net income for the year
ended March 31, 1998, the nine month period ended March 31, 1997 and the year
ended June 30, 1996, respectively.  During 1998, 1997 and 1996, $2,292,000,
$1,539,000 and $1,556,000, respectively, in dividends were received from HHII.

   The Company has a 25% investment in an Egyptian helicopter venture. The
Company's investment in the venture was $5,986,000 at March 31, 1998 and 1997.
During 1998, 1997, and 1996, $2,430,000; $1,827,000 and $2,500,000,
respectively, in dividends were received from the venture.  During 1998, the
venture's Board of Directors approved a cash dividend, of which the Company's
share applicable to fiscal year 1999 is approximately $2.0 million.

   A summary of unaudited financial information of these principal
unconsolidated entities is set forth below (thousands of dollars):

   In 1996, Bristow, with two partners, formed FBS Limited ("FBS") which was
awarded a contract to provide pilot training and maintenance services to the
Defense Helicopter Flying School ("DHFS"), a newly established training school
for all branches of the British military, under a fifteen year contract valued
at approximately (Pounds)500 million over the full term.  FBS  purchased and
specially modified 47 aircraft and maintains a staff of approximately 600
employees dedicated to conducting these training activities which began in May
1997.  As of March 31, 1998, each of the partners owned one-third (33%) of FBS.
Prior to FBS, Bristow had provided similar pilot training and maintenance
services to the British Army Air Corp. since 1963.  Bristow's partners in FBS
had similar experience at providing training service to other branches of the
British military. Bristow and its partners have given joint and several
guarantees related to the performance of this contract.

E -- DISCONTINUED OPERATIONS

     In May 1997, the Company adopted a plan to discontinue its investment in
Cathodic Protection Services Company ("CPS").  CPS manufactures, installs and
maintains cathodic protection systems to arrest corrosion in oil and gas
drilling and production facilities, pipelines, oil and gas well casings,
hydrocarbon processing plants and other metal structures.  As a result of the
Company's adoption of the plan, the consolidated financial statements of the
Company and the related Notes to Consolidated Financial Statements and
supplemental data have been adjusted and restated to reflect the results of
operations and net assets of CPS as a discontinued operation in accordance with
generally accepted accounting principles.

F -- UNAUDITED SUPPLEMENTAL DATA FOR THE NINE MONTHS ENDED
     MARCH 31, 1996

     During 1997, the Company changed its fiscal year end from June 30 to March
31.  Therefore, the Company's fiscal year end for 1997 is a nine month period.
The following table represents unaudited data for the nine month period ended
March 31, 1996.

G -- INVESTMENT IN MARKETABLE SECURITIES

     Under the provisions of SFAS No. 115, investments in debt and equity
securities are required to be classified in one of three categories:  held-to-
maturity, available-for-sale, or trading.  As of March 31, 1998 and 1997, the
Company had (Pounds)4.8 million ($8.0 million and $7.8 million, respectively) of
UK government securities classified as available-for-sale included in other
assets.  There were $12,001,000 sales of investments in U.S. Treasury
investments during the nine month period ended March 31, 1997.  The proceeds
approximated the carrying cost of the investments.  There were $3,985,000 sales
of investments in U.S. Treasury investments for the year ended June 30, 1996.

H -- COMMITMENTS AND CONTINGENCIES

     The Company has noncancelable operating leases in connection with the lease
of certain equipment, land and facilities. Rental expense incurred under these
leases was $1,872,000 in 1998; $1,925,000 in 1997 and $1,998,000 in 1996. As of
March 31, 1998, aggregate future payments under noncancelable operating leases
are as follows: 1999 -- $1,983,000; 2000 -- $1,881,000; 2001 --$1,806,000; 
2002 -- $1,608,000 and 2003 -- $1,570,000.


     On August 6, 1997, the domestic pilots at the Company voted to become
members of the Office and Professional Employees International Union ("OPEIU").
The Company commenced contract negotiations with the OPEIU on April 1, 1998 and
it is not certain how long this process may take. During the fiscal year ended
March 31, 1998, $98.4 million of operating revenues were from the Company's
domestic helicopter operations. In January 1998, the OPEIU petitioned the
National Mediation Board ("NMB") to organize the Company's domestic mechanics
and ground support personnel. Certain objections to this petition were filed and
the NMB dismissed the OPEIU application on May 12, 1998. Under the Federal labor
law rules, the union is prohibited from petitioning the NMB for one-year from
date of dismissal. The Company does not believe that the result of these
organizing efforts will place it at a competitive disadvantage with its
competitors as management believes that pay scales and work rules will continue
to be similar throughout the industry.

</TABLE>

   The valuation allowance was established for the deferred tax asset related to
foreign tax credits.  Companies may use foreign tax credits to offset the United
States income taxes due on income earned from foreign sources.  However, the
credit is limited by the total income on the United States income tax return as
well as by the ratio of foreign source income in each statutory category to
total income.  Excess foreign tax credits may be carried back two years and
forward five years.  As of March 31, 1998 and 1997, the Company did not believe
it was more likely than not that it would generate sufficient foreign sourced
income within the appropriate period to utilize all the foreign tax credits.

   The Internal Revenue Service has examined the Company's Federal income tax
returns for all years through 1994.  The years have been closed through 1994,
either through settlement or expiration of the statute of limitations.  The
Company believes that it has made adequate provision for income taxes that may
become payable with respect to open tax years.

   Unremitted foreign earnings reinvested abroad upon which deferred income
taxes have not been provided aggregated approximately $18.8 million at March 31,
1998.   Due to the timing and circumstances of repatriation of such earnings, if
any, it is not practicable to determine the unrecognized deferred tax liability
relating to such amounts.  Withholding taxes, if any, upon repatriation would
not be significant.

   Income taxes paid during 1998, 1997 and 1996 were $4,516,000;  $8,454,000 and
$5,656,000, respectively.

J -- EMPLOYEE BENEFIT PLANS

SAVINGS AND RETIREMENT PLANS

   The Company currently has two qualified defined contribution plans, which
cover substantially all employees other than Bristow employees.

   The Offshore Logistics, Inc. Employee Savings and Retirement Plan ("OLOG
Plan") covers Corporate and Air Log employees.   Under the OLOG Plan, except for
those employees working in the state of Alaska, the Company matches each
participant's contributions up to 3% of the employee's compensation.  In
addition, if net income exceeds 10% of stockholders' investment at the beginning
of the year, the Company contributes funds to acquire Company stock up to an
additional 3% of the employee's compensation, subject to a scheduled vesting
period.  Under the OLOG Plan, for Air Log employees working in the state of
Alaska, the Company matches each participant's contributions up to 4% of the
employee's compensation.

   The Grasso Production Management, Inc. Thrift & Profit Sharing Trust covers
eligible GPM employees.  The Company matches 25% of each participant's
contributions up to 6% of the employee's compensation.

   Bristow has a defined benefit retirement plan, which covers all full-time
employees of Bristow.  The plan is funded by contributions partly from employees
and partly from Bristow.  Members contribute up to 7.5% of pensionable salary
(as defined) and can pay additional voluntary contributions to provide
additional benefits.  The benefits are based on the employee's  annualized
average last three years pensionable salaries.  Plan assets are held in separate
trustee administered funds, which are primarily invested in United Kingdom and
other overseas equities and bonds.

   The following table sets forth the plan's funded status and pension costs
recognized by the Company in accordance with the provisions of SFAS No. 87

INCENTIVE AND STOCK OPTION PLANS

   Under the 1994 Long-Term Management Incentive Plan ("1994 Plan"), a total of
900,000 shares of Common Stock, or cash equivalents of Common Stock, are
available for awards to officers and key employees.  Awards granted under the
1994 Plan may be in the form of stock options, stock appreciation rights,
restricted stock, deferred stock, other stock-based awards or any combination
thereof.  Options become exercisable at such time or times as determined at the
date of grant, and expire no more than ten years after the date of grant.
Incentive stock option prices are determined by the Board and cannot be less
than fair market value at date of grant.  Non-qualified stock option prices
cannot be less than 50% of the fair market value at date of grant.

   The Annual Incentive Compensation Plan ("Annual Plan") provides for an annual
award of cash bonuses to key employees based on pre-established objective
measures of Company performance.  Participants are permitted to receive all or
any part of their annual incentive bonus in the form of shares of Restricted
Stock in accordance with the terms of the 1994  Plan.  The amount of bonuses
related to this plan were $838,000; $565,000 and $124,000 for the year ended
March 31, 1998, the nine  month period ended March 31, 1997 and the year ended
June 30, 1996, respectively.  As of March 31, 1998 there were 28,594 shares of
Restricted Stock outstanding issued at a weighted average price of $18.93 per
share.

   The 1991 Non-qualified Stock Option Plan for Non-employee Directors ("1991
Plan") provides for 200,000 shares of Common Stock to be reserved for issuance
pursuant to such plan.  As of the date of each annual meeting each non-employee
director, who meets certain attendance criteria, will automatically be granted
an option to purchase 2,000 shares of the Company's Common Stock. The exercise
price of the options granted shall be equal to the fair market value of the
Common Stock on the date of grant and are exercisable not earlier than six
months after the date of grant.

   Under the Company's stock option plans there were 876,302 shares of Common
Stock reserved for issue at March 31, 1998.

   In October 1995, the FASB issued SFAS No. 123, "Accounting for Stock-Based
Compensation," which is effective for the Company's fiscal year beginning July
1, 1995.  Under SFAS No. 123, companies can either record expense based on the
fair value of stock-based compensation upon issuance or elect to remain under
the APB 25 method whereby no compensation cost is recognized upon grant if
certain requirements are met.  The Company elected to continue to account for
its stock-based compensation under APB 25.  However, pro forma disclosures as if
the Company adopted the cost recognition requirements under SFAS No. 123 are
presented below.

   Had compensation cost been determined based on the fair value at the grant
date consistent with the provisions of SFAS No. 123, the Company's net income
and earnings per common share would have approximated the pro forma amounts
below:

respectively; and the weighted average exercise price of those options was
$12.44; $10.02 and $9.25, respectively.

   The weighted average fair value at date of grant for options granted during
1998, 1997 and 1996 was $6.48, $5.30 and $4.35 per option, respectively.  The
fair value of options granted during the periods presented is estimated on the
date of grant using the Black-Scholes option-pricing model with the following
assumptions: (a) dividend yield of 0.00%; (b) average expected volatility of
40%; (c) average risk-free interest rate of 6.4% and (d) expected life of 3
years.

K -- EARNINGS PER SHARE

     In 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards (SFAS) No. 128, "Earnings Per Share".  SFAS No.
128 replaced the previously reported primary and fully-diluted earnings per
share with basic and diluted earnings per share.

     Basic earnings per common share were computed by dividing net income by the
weighted average number of shares of common stock outstanding during the year.
Diluted earnings per common share for the twelve months and nine months ended
March 31, 1998 and 1997 were determined on the assumptions that the convertible
debt was converted on April 1, 1997 and upon issuance on December 17, 1996,
respectively.  The Company adopted SFAS No. 128, "Earnings Per Share", effective
December 15, 1997.  All income per share amounts for all periods have been
presented, and where necessary, restated to conform to the requirements of SFAS
No. 128.  The following table sets forth the computation of basic and diluted
income from continuing operations per share:

   The Company adopted a stockholder rights plan on February 9, 1996, designed
to assure that the Company's stockholders receive fair and equal treatment in
the event of any proposed takeover of the Company and to guard against partial
tender offers, squeeze-outs, open market accumulations and other abusive tactics
to gain control without paying all stockholders a fair price.  The rights plan
was not adopted in response to any specific takeover proposal.  Under the rights
plan, the Company declared a dividend of one right ("Right") on each share of
the Company's common stock.  Each Right will entitle the holder to purchase one
one-hundredth of a share of a new Series A Junior Participating  Preferred
Stock, par value $1.00 per share, at an exercise price of $50.00.  Each Right
will entitle its holder to purchase a number of common shares of the Company
having a market value of twice the exercise price.  The Rights are not currently
exercisable and will become exercisable only in the event a person or group
acquires beneficial ownership of 10 percent or more of the Company's common
stock.  The dividend distribution was made on February 29, 1996 to stockholders
of record on that date.  The Rights will expire on February 26, 2006.

   During 1998, 1997 and 1996,  Air Log and Bristow conducted operations in
approximately 22 foreign countries as well as in the United States and the
United Kingdom.  Due to the nature of the principal assets of the Company, they
are regularly and routinely moved between operating areas (both domestic and
foreign) to meet changes in market and operating conditions. Revenue earned from
any single customer did not exceed 10% of total revenues during 1998, 1997 or
1996. Equipment registered in one country is chartered to other operating areas
from time to time at rates sufficient to cover costs plus a reasonable return.
These revenues ($15,406,000 in 1998; $7,063,000 in 1997 and $7,441,000  in 1996)
have been eliminated in the amounts shown above.

N -- SUPPLEMENTAL CONDENSED CONSOLIDATING FINANCIAL INFORMATION


   On January 27, 1998, the Company completed the sale of $100 million 7 7/8%
Senior Notes due 2008, which were discounted to yield 7.915%.  The net proceeds
to the Company were $97.2 million.  In connection with the sale of the Senior
Notes, certain of the Company's subsidiaries (the "Guarantor Subsidiaries")
jointly, severally and unconditionally guaranteed the payment obligations under
the Senior Notes.  The following supplemental financial information sets forth,
on an unconsolidated basis, the balance sheet, statement of income and cash flow
information for Offshore Logistics, Inc. ("Parent Company Only"), for the
Guarantor Subsidiaries and for Offshore Logistics, Inc.'s other subsidiaries
(the "Non-Guarantor Subsidiaries").

   The supplemental condensed consolidating financial information has been
prepared pursuant to the rules and regulations for condensed financial
information and does not include all disclosures included in annual financial
statements, although the Company believes that the disclosures made are adequate
to make the information presented not misleading.  Certain reclassifications
were made to conform all of the financial information to the financial
presentation on a consolidated basis.  The principal eliminating entries
eliminate investments in subsidiaries, intercompany balances and intercompany
revenues and expenses.

   During 1998, the Company formed a new wholly owned subsidiary and contributed
the Company's operating assets, separate from its investment in its
subsidiaries, to the newly formed subsidiary.  The subsidiary is a Guarantor
Subsidiary.  For purposes of the historical supplemental financial information,
the Company has presented the aforementioned operating assets and related
operating results together with the operating assets and results of other
Guarantor Subsidiaries.

   The allocation of the consolidated income tax provision was made using the
with and without allocation method.
