                         LOAN AND SECURITY AGREEMENT OF

     FIRST AMENDMENT (the "Amendment") dated June 13, 1996 between Canpartners
Investments IV, LLC, a California limited liability company, as Lender (the
"Lender"), and National Airmotive Corporation, a California corporation, as
Borrower (the "Borrower") to the Loan and Security Agreement dated as of June
1, 1995 between the Lender, as assignee of Canpartners Investments III, L.P., a
California limited partnership, and the Borrower.

     PRELIMINARY STATEMENTS:

     (1)  Pursuant to that certain Loan and Security Agreement dated as of 
June 1, 1995 (the "Loan Agreement"), Canpartners Investments III, L.P.  made a 
loan to Borrower in the original principal amount of Three Million Dollars
($3,000,000) (the "Loan"). Canpartners Investments III, L.P. has assigned its
rights and obligations under the Loan Agreement and all documents entered into
in connection with the Loan to the Lender.

     (2)  The Loan is (a) evidenced by a Promissory Note duly executed and
delivered by the Borrower to the Lender, (b) secured by the Collateral, and (c)
to be repaid, together with interest and other amounts, in accordance with the
Loan Agreement, the Promissory Note and the other Financing Agreements.

     (3)  On the same date as the Loan Agreement was entered into and the Loan 
was made, the Borrower entered into a Loan and Security Agreement with Congress
Financial Corporation (Western) ("Congress") for a credit facility in the total
amount of $30 million, secured by the collateral provided for in such loan
agreement, to finance the acquisition of the Borrower and to provide working
capital for the Borrower.

     (4)  The Lender, First Aviation Services, Inc. and Congress also entered 
into an Intercreditor and Subordination Agreement dated June 1, 1995 in 
connection with the Loan and the Borrower's credit facility with Congress.

     (5)  The Borrower desires to terminate the credit facility with Congress 
and to replace it with a new credit facility from Fleet Capital Corporation
("Fleet") in the maximum amount of $40 million. In connection with such
refinancing, Borrower has requested that Lender (a) consent to the Fleet credit
facility and the subordination of the Loan to the Fleet credit facility and (b)
agree to make certain modifications to the Loan Agreement and the Loan



                                       1
   2
and to reduce the number of warrants to purchase shares of common stock of the
Borrower held by the Lender. The Lender is willing to grant such consents and
to make such modifications and reductions in exchange for a current reduction
in the amount of the Loan and other modifications to the terms of the Loan.

     (6)  Capitalized terms used in this Amendment without definition shall have
the meanings prescribed for such terms in the Loan Agreement.
