                                  RISK FACTORS

         In addition to the other information contained and incorporated by
reference in this Prospectus, you should carefully consider the following risks
before making an investment decision. If any of the following risks occurs, our
business, financial condition or results of operations could be adversely
affected. In that case, the trading price of our Class A common stock could
decline, and you might lose all or part of your investment.

Our success is highly dependent on the performance of the aviation industry

         Economic factors and passenger security concerns that affect the
aviation industry also affect our business. The aviation industry has
historically been subject to downward cycles from time to time which reduce the
overall demand for jet engine replacement parts and repair and overhaul
services, as well as result in lower prices and greater credit risk. These
economic factors and passenger security concerns can indirectly have a material
adverse effect on our business, financial condition and results of operations.

If our customers do not pay us for our equipment and services, our financial
condition could be negatively impacted

         Typically, downward economic cycles may more adversely affect our
smaller customers than our larger customers and, as a result, our smaller
customers may pose greater credit risks to us as a result of our inability to
collect receivables from a substantial sale to any of them. However, the entire
airline industry's financial condition has been weakened substantially following
the events that occurred on September 11, 2001 and we might be unable to collect
receivables from larger commercial carriers, as well.

We are subject to governmental regulation and our failure to comply with these
regulations could cause the government to withdraw or revoke our authorizations
and approvals to do business and could subject us to penalties and sanctions
that could harm our business

         Governmental agencies throughout the world, including the U.S. Federal
Aviation Administration, or FAA, highly regulate the repair and overhaul of
aircraft engines and components. Guidelines established by original equipment
manufacturers supplement governmental regulation and generally require that
aircraft operators overhaul engines and replace specified engine parts after a
specified number of flight hours or cycles (take-offs and landings).

         We include with the replacement parts that we sell to our customers
documentation certifying that each part complies with applicable regulatory
requirements and meets applicable standards of airworthiness established by the
FAA or the equivalent regulatory agencies in other countries. In addition, our
repair and overhaul operations are subject to certification pursuant to
regulations established by the FAA. Specific regulations vary from country to
country, although compliance with FAA requirements generally satisfies
regulatory requirements in other countries. The revocation or suspension of any
of our material authorizations or approvals would have an adverse effect on our
business, financial condition and results of operations. New and more stringent
government regulations, if adopted and enacted, could have an adverse effect on
our business, financial condition and results of operations.

The retirement of commercial aircraft that use JT8D aircraft engines could
reduce our revenues

         Approximately 21% of our net sales during the year ended October 31,
2001 consisted of sales of replacement parts for the Pratt & Whitney JT8D
aircraft engine and its component engine parts. As a result of the events that
occurred on September 11, 2001 and other factors, we believe that at least 50%
of the JT8D aircraft engines that were in service prior to such date have been
or will be retired by December 31, 2002.

         Supply and demand substantially affect the aftermarket for JT8D
aircraft engine parts. A significant increase in supply or reduction in demand
could have a material adverse effect on our business, financial condition and
results of operations. An unanticipated wind-down or liquidation of an air
carrier operating a large number of JT8D aircraft engines could cause a
significant increase in the supply of replacement parts using retired JT8D
aircraft engines. A change in preferences or the imposition of regulations
affecting the use of JT8D aircraft engines could also reduce demand. The
following are examples of factors that could decrease demand for JT8D aircraft
engines:


                                       3


         o   Hush-Kits. The FAA and the European Union have implemented noise
reduction regulations that reduce the number of older model JT8D aircraft
engines that may be operated in the United States and the member nations of the
European Union unless noise reduction equipment, known as hush-kits, are added
to the aircraft engines. Additional noise reduction quotas imposed by
communities surrounding some major European cities further restrict the
operation of hush-kitted aircraft engines in those markets. The failure to
hush-kit JT8D aircraft engines could significantly reduce the demand for JT8D
aircraft engines, resulting in an oversupply of JT8D aircraft engines and
component engine parts. This, in turn, could decrease the value of our products
and have a material adverse effect on our business, financial condition and
results of operations. Aircraft operators may replace their older model JT8D
aircraft engines with newer, quieter aircraft engines, rather than install
hush-kits on them.

         o   Other Regulations. Other regulations in both the United States and
the European Union impose stringent inspection, upgrading, maintenance and
retrofit requirements on aging aircraft and aircraft engines that increase the
cost of operating older model aircraft and aircraft engines.

         o   Passenger Confidence. A decline in passenger confidence in older
aircraft and aircraft engines as a result of apparent fatigue could also
discourage aircraft operators from using JT8D aircraft engines.

         o   Emissions Standards. The U.S. Environmental Protection Agency, or
EPA, and various agencies of the European Union have sought the adoption of
stricter standards limiting the emissions of nitrous oxide from aircraft
engines. If adopted, stricter emissions standards could cause the use of JT8D
aircraft engines to become substantially more costly in the event modifications
must be made to bring aircraft engines into compliance.

         Our business may be materially harmed if aircraft that use JT8D
aircraft engines are retired and there are fewer JT8D aircraft engines that
require these parts or services or if there is an increase in the supply of
replacement parts using retired JT8D aircraft engines.

The retirement of commercial aircraft could reduce our revenues

         Our flight support group designs, manufactures and distributes jet
engine replacement parts and offers repairs and overhaul of aircraft components.
Our business may be materially harmed if aircraft for which we have replacement
parts or supply repair and overhaul services are retired and there are fewer
aircraft that require these parts or services.

Reductions in defense spending could reduce our revenues

         Approximately 70% of the sales of our Electronic Technologies Group are
derived from the sale of product and services to U.S. and foreign military
agencies. A decline in defense budgets or additional restrictions imposed by the
U.S. government on sales of products or services to foreign military agencies
could lower sales of our products and services.

Intense competition from existing and new competitors may harm our business

         We face significant competition in each of our businesses.

         Flight Support Group

            o     For jet engine replacement parts, we compete with the
                  industry's leading jet engine original equipment
                  manufacturers, particularly Pratt & Whitney.

            o     For the overhaul and repair of jet engine and airframe
                  components, we compete with

                  -     major commercial airlines, many of which operate their
                        own maintenance and overhaul units,

                  -     original equipment manufacturers, which manufacture,
                        repair and overhaul their own parts, and

                  -     other independent service companies.


                                       4


         Electronic Technologies Group.

            o     For the design and manufacture of various types of electronic
                  electro-optical optical equipment and repair of inertial
                  navigation units and other avionic equipment, we compete in a
                  fragmented marketplace with a number of companies, some of
                  which are well capitalized.

         The aviation aftermarket supply industry is highly fragmented, has
several highly visible leading companies and is characterized by intense
competition. Some of our competitors have substantially greater name
recognition, complementary lines of business and financial, marketing and other
resources than we do. In addition, original equipment manufacturers, aircraft
maintenance providers, leasing companies and FAA-certificated repair facilities
may vertically integrate into the supply industry, thereby significantly
increasing industry competition. Moreover, our smaller competitors may be able
to offer more attractive pricing of parts as a result of lower labor costs or
other factors. A variety of potential actions by any of our competitors,
including a reduction of product prices or the establishment by competitors of
long-term relationships with new or existing customers, could have a material
adverse effect on our business, financial condition and results of operations.
Competition typically intensifies during cyclical downturns in the aviation
industry, when supply may exceed demand. We may not be able to continue to
compete effectively against present or future competitors, and competitive
pressures may have a material and adverse effect on our business,
financial-condition and results of operations.

We may incur product liability claims that are not fully insured

         Our jet engine replacement parts and repair and overhaul services
expose our business to potential liabilities for personal injury or death as a
result of the failure of an aircraft component that we have designed,
manufactured or serviced. The commercial aviation industry occasionally has
catastrophic losses that may exceed policy limits. While we believe that our
liability insurance is adequate to protect us from these liabilities, and, while
no material claims related to these liabilities have been made against us,
claims may arise in the future and our insurance coverage may not be adequate.
An uninsured or partially insured claim, or a claim for which third-party
indemnification is not available, could have a material adverse effect on our
business, financial condition and results of operations. Additionally, insurance
coverage costs increased following the events that occurred on September 11,
2001 and may become even more expensive in the future. Our customers typically
require us to maintain substantial insurance coverage and our inability to
obtain insurance coverage at commercially reasonable rates could result in lower
revenues.

We may not have the administrative, operational or financial resources to
continue to grow the company

         We have experienced rapid growth in recent periods and intend to
continue to pursue an aggressive growth strategy, both through acquisitions and
internal expansion of products and services. Our growth to date has placed, and
could continue to place, significant demands on our administrative, operational
and financial resources. We may not be able to grow effectively or manage any
growth successfully, and the failure to do so could have a material adverse
effect on our business, financial condition and results of operations.

We may not be able to continue to acquire additional companies which would
reduce our growth

         A key element of our strategy is growth through the acquisition of
additional companies. Our acquisition strategy poses a number of challenges and
risks, including the following:

         o     Availability of suitable acquisition candidates
         o     Availability of capital
         o     Diversion of management's attention
         o     Integrating the operations and personnel of acquired companies
         o     Potential amortization of acquired intangible assets
         o     Potential loss of key employees of acquired companies
         o     Use of a significant portion of our available cash
         o     Significant dilution to our shareholders for acquisitions made
               utilizing our securities
         o     Consummation of acquisitions on satisfactory terms

         We may not be able to successfully execute our acquisition strategy,
and the failure to do so could have a material adverse effect on our business,
financial condition and results of operations.


                                       5


We may incur environmental liabilities and these liabilities are not covered by
insurance

         Our operations and facilities are subject to a number of federal, state
and local environmental laws and regulations, which govern, among other things,
the discharge of hazardous materials into the air and water as well as the
handling, storage and disposal of hazardous materials. Pursuant to various
environmental laws, a current or previous owner or operator of real property may
be liable for the costs of removal or remediation of hazardous materials.
Environmental laws typically impose liability whether or not the owner or
operator knew of, or was responsible for, the presence of hazardous materials.
Although management believes that our operations and facilities are in material
compliance with environmental laws and regulations, future changes in them or
interpretations thereof or the nature of the our operations may require us to
make significant additional capital expenditures to ensure compliance in the
future.

         We do not maintain environmental liability insurance, and the expenses
related to these environmental liabilities, if we are required to pay them,
could have a material adverse effect on our business, financial condition and
results of operations.

Our success is dependent on the development and manufacture of new products,
equipment and services

         The aviation defense and electronics industries are constantly
undergoing development and change and, accordingly, new products, equipment and
methods of repair and overhaul service are likely to be introduced in the
future. In addition to manufacturing electronic and electro-optical equipment
and selected aerospace and defense components for original equipment
manufacturers and the U.S. government and repairing jet engine and airframe
components, we re-design sophisticated jet engine replacement parts originally
developed by original equipment manufacturers so that we can offer the
replacement parts for sale at substantially lower prices than those manufactured
by the original equipment manufacturers. Consequently, we devote substantial
resources to research and product development. Technological development poses a
number of challenges and risks, including the following:

         o   We may not be able to successfully protect the proprietary
interests we have in various jet engine parts, electronic and electro-optical
equipment and our repair processes.

         o   As original equipment manufacturers continue to develop and improve
jet engines, we may not be able to re-design and manufacture replacement parts
that perform as well as those offered by original equipment manufacturers or
that we can profitably sell at substantially lower prices than the original
equipment manufacturers.

         o   We may need to expend significant capital to

               -    purchase new equipment and machines,
               -    train employees in new methods of production and service,
                    and
               -    fund the research and development of new products.

         o   Development by our competitors of patents or methodologies that
preclude us from the design and manufacture of jet engine replacement parts or
electrical and electro-optical equipment could adversely affect our business,
financial condition and results of operations.

         In addition, we may not be able to successfully develop new products,
equipment or methods of repair and overhaul service, and the failure to do so
could have a material adverse effect on our business, financial condition and
results of operations.

We are dependent on key personnel and the loss of these key personnel could have
a material adverse effect on our success

         Our success substantially depends on the performance, contributions and
expertise of our senior management team led by Laurans A. Mendelson, our
Chairman, President and Chief Executive Officer. In addition, we hire many
members of our engineering team from original equipment manufacturers, such as
General Electric and Pratt & Whitney. These technical employees are critical to
our research and product development, as well as our ability to continue to
re-design sophisticated products of original equipment manufacturers in order to
sell competing replacement parts at substantially lower prices than those
manufactured by the jet engine original


                                       6


equipment manufacturers. The loss of the services of any of our executive
officers or other key employees or our inability to continue to attract, retain
or motivate the necessary personnel could have a material adverse effect on our
business, financial condition and results of operations.

Since our executive officers and directors directly and indirectly control our
company, minority shareholders will have little say in the direction of the
company

         As of March 31, 2002, collectively our executive officers and entities
controlled by them, our 401(k) Plan and members of the Board of Directors
beneficially owned approximately 35% of our outstanding Common Stock and
approximately 20% of our outstanding Class A Common Stock. Accordingly, they
will be able to substantially influence the election of the Board of Directors
and control our business, policies and affairs, including the approval of
business combinations and defeating any attempted takeover.

We have adopted provisions in our articles of incorporation and bylaws and are
subject to certain corporate laws that could prevent a change in control of the
company

         Articles and Bylaws. Some of the provisions of our articles of
incorporation and bylaws may be deemed to have anti-takeover effects and may
discourage, delay, defer or prevent a takeover attempt that a shareholder might
consider in its best interest. These provisions do the following:

          o    They establish advance notice procedures for the nomination of
               candidates for election as directors and for shareholder
               proposals to be considered at annual shareholders' meetings.

          o    They provide that special meetings of the shareholders may be
               called by the Chairman of the Board of Directors, the President
               of the Company or by a majority of the Board.

          o    They authorize the issuance of 10,000,000 shares of preferred
               stock with the designations, rights, preferences and limitations
               as may be determined from time to time by the Board.

          o    They authorize the issuance of 30,000,000 shares of Class A
               Common Stock having 1/10th vote per share.

         Accordingly, without shareholder approval, the Board can, among other
things,

          o    issue preferred stock with dividend, liquidation, conversion,
               voting or other rights that could adversely affect the voting
               powers or other rights of holders of the Common Stock and Class A
               Common Stock, and

          o    help maintain existing shareholders' voting power and deter or
               frustrate takeover attempts that a holder of Common Stock might
               consider to be in his or her best interest by issuing Class A
               Common Stock.

         Rights. In addition, one preferred stock purchase right trades with
each outstanding share of Common Stock and Class A Common Stock. Each right
entitles the registered holder to purchase from us one one-hundredth (1/100) of
a share of a Series A Junior Participating Preferred Stock, at a price of $45
per one one-hundredth (1/100) of a share, subject to adjustment. The rights are
not exercisable or transferable apart from the common stock until a person or
group acquires 15% or more of the outstanding common stock or commences, or
announces an intention to commence, a tender offer for 30% or more of the
outstanding common stock. The rights expire on November 2, 2003, and will cause
substantial dilution to a person or a group who attempts to acquire HEICO on
terms not approved by the Board or who acquires 15% or more of the outstanding
common stock without approval of the Board. We can redeem the rights at $.01 per
right at any time until the close of business on the tenth day after a person or
group has obtained beneficial ownership of 15% or more of the outstanding common
stock or until a person commences or announces an intention to commence a tender
offer for 30% or more of the outstanding common stock.

         Subject to adjustment, holders of shares of the Series A Junior
Participating Preferred Stock will be entitled to, among other things, (x)
receive, when, as and if declared by the Board of Directors, (i) cash dividends
in an amount per share equal to 100 times the aggregate per share amount of all
cash dividends declared or paid on the


                                       7


common stock, (ii) a quarterly preferential cash dividend of $.75 per share,
less cash dividends declared pursuant to clause (i), and (y) 100 votes per share
of Series A Junior Participating Preferred Stock on all matters submitted to a
vote of the shareholders and the right to vote together with the holders of
shares of common stock as a single voting group on all matters submitted to a
vote of the shareholders.

         Florida Law. Furthermore, some of the provisions of the Florida
Business Corporation Act could have the effect of delaying, deferring or
preventing a change in control.

                              PLAN OF DISTRIBUTION

General

         Pursuant to the terms of the contractual registration rights granted to
the selling shareholder by us, except pursuant to a firm commitment
underwriting, the selling shareholder must sell the Class A Common Stock in the
manner and at the prices described in this paragraph. The selling shareholder
must provide us with a written notice of its intent to sell any shares of the
Class A Common Stock and we must designate, within three business days following
the receipt of such notice, a securities broker to sell these shares on behalf
of the selling shareholder. Without our consent, the selling shareholder can not
offer to sell more than 10,000 shares at any time and can not sell more than
25,000 shares during any five trading days. The selling shareholder must
instruct the designated securities broker to sell the shares at the best
available market prices during the 14-day period following the date the selling
shareholder places the order to sell the shares.

         Agents, dealers or underwriters may receive compensation in the form of
underwriting discounts, concessions or commissions from the selling shareholder
and/or the purchaser(s) of shares for whom they act as agent or to whom they
sell as principals, or both. The selling shareholder and any agents, dealers or
underwriters that act in connection with the sale of shares might be deemed to
be "underwriters" within the meaning of Section 2(11) of the Securities Act, and
any discount or commission received by them and any profit on the resale of
shares as principal might be deemed to be underwriting discounts or commissions
under the Securities Act.

         Supplements. To the extent required, we will set forth in a supplement
to this Prospectus filed with the SEC the number of shares to be sold, the
purchase price and public offering price, the name or names of any agent, dealer
or underwriter, and any applicable commissions or discounts with respect to a
particular offering.

         State Securities Law. Under the securities laws of some states, the
selling shareholder may only sell the shares in those states through registered
or licensed brokers or dealers. In addition, in some states the selling
shareholder may not sell the shares unless they have been registered or
qualified for sale in that state or an exemption from registration or
qualification is available and is satisfied.

         Expenses; Indemnification. We will not receive any of the proceeds from
the sale of the Class A Common Stock sold by the selling shareholder hereunder
and will bear all expenses related to the registration of this offering


                                       9


but will not pay for any underwriting commissions, fees or discounts, if any. We
will indemnify the selling shareholder against some civil liabilities, including
some liabilities which may arise under the Securities Act.

                                  LEGAL MATTERS

         The validity of the issuance of the shares of Class A Common Stock
offered hereby will be passed upon by Greenberg Traurig, P.A., Miami, Florida.

Item 15. Indemnification of Directors and Officers.

         The Registrant has authority under Section 607.0850 of the Florida
Business Corporation Act to indemnify its directors and officers to the extent
provided in such statute. The Registrant's Articles of Incorporation provide
that the Registrant may indemnify its executive officers and directors to the
fullest extent permitted by law whether now or hereafter. The Registrant has
entered or will enter into an agreement with each of its directors and certain
of its officers wherein it has agreed to indemnify each of them to the fullest
extent permitted by law.

         The provisions of the Florida Business Corporation Act that authorize
indemnification do not eliminate the duty of care of a director, and in
appropriate circumstances equitable remedies such as injunctive or other forms
of nonmonetary relief will remain available under Florida law. In addition, each
director will continue to be subject to liability for (a) violations of the
criminal law, unless the director had reasonable cause to believe his conduct
was lawful or had no reasonable cause to believe his conduct was unlawful; (b)
deriving an improper personal benefit from a transaction; (c) voting for or
assenting to an unlawful distribution; and (d) willful misconduct or a conscious
disregard for the best interests of the Registrant in a proceeding by or in the
right of the Registrant to procure a judgment in its favor or in a proceeding by
or in the right of a shareholder. The statute does not affect a director's
responsibilities under any other law, such as the federal securities laws or
state or federal environmental laws.

Item 17. Undertakings.

         (a) The undersigned Registrant hereby undertakes: (1) to file, during
any period in which offers or sales are being made, a post-effective amendment
to this Registration Statement: (i) to include any prospectus required by
Section 10(a)(3) of the Securities Act of 1933; (ii) to reflect in the
prospectus any facts or events arising after the effective date of the
Registration Statement (or the most recent post-effective amendment thereof)
which, individually or in the aggregate, represent a fundamental change in the
information set forth in the Registration Statement; and (iii) to include any
material information with respect to the plan of distribution not previously
disclosed in the Registration Statement or any material change to such
information in the Registration Statement; (2) that, for the purpose of
determining any liability under the Securities Act of 1933, each such
post-effective amendment shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at the time shall be deemed to be the initial bona fide offering thereof, and
(3) to remove from registration by means of a post-effective amendment any of
the securities being registered which remain unsold at the termination of the
offering.

         (b) The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act of 1934 (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Exchange Act) that is
incorporated by reference in the Registration Statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

         (c) Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the Registrant pursuant to the foregoing provisions, or otherwise,
the Registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been, settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.
