EXHIBIT 99.1

July 17, 2003

TO THE MEMBERS OF THE BOARD OF DIRECTORS OF HEICO CORPORATION AND THE EXECUTIVE
OFFICERS OF HEICO CORPORATION

RE:      TEMPORARY SUSPENSION OF TRADING IN SECURITIES OF HEICO CORPORATION

This notice is to inform you that the HEICO Savings and Investment Plan ("Plan")
will be changing recordkeepers and investment options. As a result of these
changes, participants in the Plan will temporarily be unable to direct or
diversify their investments in the Plan, obtain a loan from the Plan, or obtain
a distribution from the Plan. This period, during which participants will be
unable to exercise these rights otherwise available under the Plan, is called a
"blackout period". The blackout period for the Plan is expected to begin on
August 15, 2003 and end on November 30, 2003.

Under SEC regulations adopted earlier this year in response to Section 306(a) of
the Sarbanes-Oxley Act of 2002, any director or executive officer of an issuer
of any equity security is prohibited from, directly or indirectly, purchasing,
selling or otherwise acquiring or transferring any equity security of the issuer
during a pension fund blackout period that temporarily prevents plan
participants or beneficiaries from engaging in equity securities transactions
through their plan accounts, if the director or executive officer acquired the
equity security in connection with his or her service or employment as a
director or executive officer. Accordingly, during the blackout period for the
Plan, you may not exercise any stock options or sell any shares of HEICO Common
Stock or HEICO Class A Common Stock that you acquired in connection with your
service or employment as a director or executive officer of HEICO Corporation.

If you have any questions on this matter, please contact Victor Mendelson at
305-374-1745 ext. 7590 or me at 954-744-7560.

Kindest regards,



Thomas S. Irwin
Executive Vice President
Chief Financial Officer
