         RE:  Registration Statement on Form S-8 (the "Registration Statement")

Gentlemen:

         We have acted as counsel to HEICO Corporation, a Florida corporation
(the "Company"), in connection with the preparation and filing by the Company
with the Securities and Exchange Commission of the Registration Statement under
the Securities Act of 1933, as amended (the "Securities Act"). The Registration
Statement relates to the offering and sale by the Company of up to 520,000
shares of the Company's (i)(a) Common Stock, par value $0.01 per share (the
"Common Stock") or (b) Class A Common Stock, par value $0.01 per share (the
"Class A Common Stock", and together with the Common Stock, the "Shares"), and
(ii) related Preferred Stock Purchase Rights, pursuant to stock options granted
or to be granted under the Company's 2002 Stock Option Plan (the "Plan").

         We have examined such corporate records, documents, instruments and
certificates of the Company and have reviewed such questions of law as we have
deemed necessary, relevant or appropriate to enable us to render the opinion
expressed herein. In such examination, we have assumed the genuineness of all
signatures and authenticity of all documents, instruments, records and
certificates submitted to us as originals.

         Based upon such examination and review, we are of the opinion that when
the Registration Statement becomes effective under the Securities Act and the
Shares are issued in accordance with the terms and conditions of the Plan, the
Shares will be validly issued, fully paid and non-assessable securities of the
Company.

         The opinion expressed herein is limited to the corporate laws of the
State of Florida, and we express no opinion as to the effect on the matters
covered by any other jurisdiction.

         This firm consents to the filing of this opinion as an exhibit to the
Registration Statement and to all references to the firm in the Registration
Statement.

                                                     Very truly yours,

                                                     AKERMAN SENTERFITT
