            HEICO CORPORATION REPORTS IMPROVED THIRD QUARTER RESULTS

HOLLYWOOD, FL, and MIAMI, FL -- HEICO CORPORATION (NYSE: HEI and HEI.A), today
reported that net income for the third quarter of fiscal 2003 increased by 15%
to $3,240,000, or 15 cents per share, from $2,829,000, or 13 cents per share,
for the third quarter of fiscal 2002. Net sales for the third quarter of fiscal
2003 were up 7% to $45,412,000 from $42,587,000 in the third quarter of fiscal
2002.

For the first nine months of fiscal 2003, net income totaled $8,682,000, or 39
cents per share, on sales of $128,791,000. Net income for the first nine months
of fiscal 2002 was $9,627,000, or 43 cents per share, on sales of $126,600,000.
Net income for the first nine months of fiscal 2002 included $765,000, or 3
cents per share, from the after tax gain on the sale of a product line.

Cash flow from operating activities totaled $18.1 million for the first nine
months of fiscal 2003, up $3.5 million from the first nine months of fiscal
2002, and equaled approximately 200% of the Company's net income.

Operating income increased 23% to $6,101,000 in the third quarter of fiscal 2003
from $4,954,000 in the third quarter of fiscal 2002. The improvement in
operating income for the third quarter of fiscal 2003 was driven by higher sales
and earnings within the Company's Flight Support Group (FSG). For the first nine
months of fiscal 2003, operating income totaled $16,561,000 and approximated
operating income for the same period of the prior year of $16,719,000. Operating
income in the first nine months of fiscal 2003 principally reflects increased
earnings within the FSG, offset by lower earnings within the Company's
Electronic Technologies Group (ETG).

Sales within the FSG increased 10% to $32,742,000 in the third quarter of fiscal
2003 from $29,724,000 in the third quarter of fiscal 2002 reflecting increased
revenues principally related to sales of new products and services and some
recovery within the commercial aerospace industry. For the first nine months of
fiscal 2003, FSG sales increased 8% to $95,004,000 from $88,316,000 in the first
nine months of fiscal 2002, which is primarily attributable to new products and
services.

                                     -more-


Operating income of the FSG in the third quarter of fiscal 2003 increased 34% to
$4,797,000 from $3,577,000 in the third quarter of fiscal 2002 and increased 23%
to $14,336,000 in the first nine months of fiscal 2003 from $11,683,000 in the
first nine months of fiscal 2002. These increases primarily reflect higher sales
and improved operating margins, which increased with the higher sales levels.

Sales and operating income within the ETG of $12,814,000 and $2,702,000,
respectively, for the third quarter of fiscal 2003 approximated sales and
operating income for the third quarter of fiscal 2002 of $12,970,000 and
$2,698,000, respectively. For the first nine months of fiscal 2003, sales and
operating income within the ETG were $34,102,000 and $5,374,000, respectively,
versus $38,734,000 and $8,789,000 in the first nine months of fiscal 2002. The
decreases for the nine-month period primarily resulted from lower foreign
military sales. In addition, operating margins were somewhat lower in the
nine-month period due to a less favorable product mix.

Laurans A. Mendelson, HEICO's Chairman, President & Chief Executive Officer,
remarked, "We are pleased to report continued improvements in sales and earnings
for our Flight Support Group in fiscal 2003 versus fiscal 2002. The increases in
the third quarter are a result of our continuing new product development efforts
and also reflect some recent recovery in commercial aviation, both domestically
and overseas. The commercial aerospace industry has recently been positively
affected by the end of military conflict in Iraq and the subsiding impact of
SARS.

"Our Electronic Technologies Group also reported an improved trend in sales and
operating income in the fiscal 2003 third quarter. Third quarter fiscal 2003
sales and operating income were up 14% and 42%, respectively, compared to the
second quarter of fiscal 2003. These increases reflect the shipments of some of
the products whose delivery was delayed in the first half of the year.

"In addition, our cash flow from operations remained strong at an annualized
rate in excess of $20 million, allowing us to reduce borrowings under our
revolving credit facility by another $4 million in the third quarter to an
aggregate reduction of $12 million since our last fiscal year end. July 2003
also marked another milestone for HEICO, when we paid our 50th consecutive
semi-annual cash dividend since 1979.

"Based on the recent uptick in the commercial aerospace industry and our
continued success in introducing our new products and services, we are now
targeting fiscal 2003 earnings at the high end of the previously reported range
of 50 to 55 cents per share on sales growth of 2% to 3% over our fiscal 2002
sales."

28, 2003 at 8:30 a.m. Eastern time to discuss its third quarter results.

increase; governmental and regulatory demands, export policies and restrictions,
military program funding by U.S. and non-U.S. Government agencies or competition
on military programs, which could reduce our sales; HEICO's ability to introduce
new products and product pricing levels, which could reduce our sales or sales
growth; HEICO's ability to make acquisitions and achieve operating synergies
from acquired businesses, customer credit risk, interest rates and economic
conditions within and outside of the aerospace, defense and electronics
