Re:      Registration Statement on Form S-3 Covering 645,000
         Shares of Common Stock of American Aircarriers Support, Incorporated

Gentlemen:

         We have acted as counsel to American Aircarriers Support, Incorporated,
a Delaware corporation (the "Company"), in connection with the proposed offering
of 645,000 shares of Common Stock (the "Shares") 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-3 expected to be filed by the Company with the
Securities and Exchange Commission on or about November 22, 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.

         3. With respect to 20,000 of the Shares to be issued upon exercise of
outstanding options under the Company's 1998 Omnibus Stock Option Plan, as
amended (the "Plan") and on receipt of the consideration required by, and when
issued in accordance with the terms and conditions of the Plan, such Shares will
constitute duly and validly issued, outstanding, and fully paid and
nonassessable securities of the Company. The remaining 625,000 Shares 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.
