                          LOAN AND SECURITY AGREEMENT
 
    This Consent and Amendment No. 3 to Loan and Security Agreement (this
"Amendment") is made as of May 29, 1998, among DeCrane Aircraft Holdings, Inc.,

(the "Avtech Acquisition") by Borrower of not less than 99.44% of the

entered into in connection therewith, or (b) a waiver, release or limitation
upon the exercise by Agent or any Lender of any of its rights, legal or
equitable, hereunder. Except as set forth above, Agent and each Lender reserves
any and all rights and remedies which it has had, has or may have under the Loan
Agreement.
