Re:      Registration Statement on Form S-8 Covering 900,000
         Shares of Common Stock Reserved for Issuance Under
         the American Aircarriers Support, Incorporated 1998 Omnibus Stock
         Option Plan

Gentlemen:

         We have acted as counsel to American Aircarriers Support, Incorporated,
a Delaware corporation (the "Company"), in connection with the proposed offering
by the Company of 900,000 shares of Common Stock (the "Shares") reserved for
issuance under the Company's 1998 Omnibus Stock Option Plan (the "Plan") in
accordance with the registration provisions of the Securities Act of 1933, as
amended.

         In such capacity, we have examined, among other documents, the
Registration Statement on Form S-8 expected to be filed by the Company with the
Securities and Exchange Commission on or about September 17, 1999 (as the same
may be amended from time to time, the "Registration Statement"), covering the
offering of the Shares.

         Based on the foregoing and on such further examination as we have
deemed relevant and necessary, we are of the opinion that:

         1. The Company is a corporation duly organized and validly existing
under the laws of the State of Delaware.

         2. The Shares have been legally and validly authorized under the
Certificate of Incorporation of the Company, as amended, and on receipt of the
consideration required by, and when issued in accordance with the terms and
conditions of the Plan, the Shares will constitute duly and validly issued,
outstanding, and fully paid and nonassessable securities of the Company.

         We hereby consent to the use of our name and to the references to our
firm in the Prospectus forming a part of the Registration Statement, and to the
filing of a copy of this opinion as Exhibit No. 5 thereto.

                                         Very truly yours,

                                         BERLINER ZISSER WALTER & GALLEGOS, P.C.
