SECURITY AND ISSUER This statement relates to the Common Stock ("Common Stock") of International Airline Support Group, Inc. ("IASG"), a Delaware corporation. IASG's principal executive offices are located at 1954 Airport Road, Suite 200, Atlanta, Georgia 30341. ITEM 2. IDENTITY AND BACKGROUND (a), (b) and (c) This statement is being filed by Ameristock Corporation ("Ameristock"). The principal business address of Ameristock is 1320 Harbor Bay Parkway, Suite 145, Alameda, CA 94502. Ameristock is a California corporation the principal business of which is serving as investment adviser to investment companies registered under the Investment Company Act of 1940 and their series. The directors of Ameristock are Nicholas D. Gerber, Andrew Ngim and Howard Mah, each with the business address of 1320 Harbor Bay Parkway, Suite 145, Alameda, CA 94502. Mr. Gerber's principal occupation is as President, director and controlling shareholder of Ameristock. Mr. Ngim's principal occupation is Managing Director of Ameristock, and Mr. Mah's principal occupation is as a portfolio manager for Ameristock. Ameristock has no executive officers other than Mr. Gerber. (d) and (e) During the last five years, no person identified in this Item 2 has been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors), or has been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, Federal or State securities laws or finding any violation with respect to such laws. (f) Each of the natural persons identified in this Item 2 is a United States citizen. ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION The Common Stock was acquired with funds of approximately $643,520.20. All such funds were provided from the assets of the Ameristock Focused Value Fund (the "Fund"), an investment company series for which Ameristock serves as investment adviser. ITEM 4. PURPOSE OF TRANSACTION The Common Stock had been acquired by Ameristock's advisory client, the Fund, for the purpose of investment. Ameristock sold the Common Stock on behalf of the Fund because it no longer believed that the Common Stock would help the Fund meet its investment objective. Ameristock does not have any plan or proposal to acquire any securities of IASG on behalf of the Fund or otherwise, or to take any other action that would involve one or more of the types of transactions or have one or more of the results described in Item 4, although it reserves the right to do so in the future. CUSIP NO. 458865201 Page 5 of 5 Pages Schedule 13G ITEM 5. INTEREST IN SECURITIES OF THE ISSUER (a-b) The Fund is no longer the owner of any shares of the Common Stock. A Management Agreement with the Fund grants to Ameristock sole voting and investment discretion over the securities owned by the Fund. Therefore, Ameristock may be deemed to be, for purposes of Rule 13d-3 under the 1934 Act, the beneficial owner of any Common Stock that was or in the future is owned by the Fund. (c) On April 23, 2003, Ameristock sold the Fund's entire interest in IASG, amounting to 502,088 shares of Common Stock, in a transaction in the over-the-counter market. The Fund received $.0006 per share of common stock in connection with such sale. (d) No person other than the Fund had the right to receive or the power to direct the receipt of dividends from, or proceeds of the sale of the securities being reported herein. (e) April 23, 2003.
