stock option granted by JetFleet Holding Corp. ("JHC") for 20,000 shares of ACY

investment funds (except in the case of the gifts noted below), acquired
beginning in 1998 through February 20, 2003, beneficial ownership of 12,900

Stock were distributed to CMA Capital Group, Inc. ("Group"), the general partner
of JetFleet I and JetFleet II pursuant to the Merger Agreement, and distributed
to Group's parent, CMA Capital Corporation ("Cap Corp."), and then by Cap Corp.

capital. On March 28, 2002, S-Corp. purchased, using working capital, 51,219
shares of Common Stock from CMA and CMACM, but this did not represent a change
in beneficial ownership of the shares.









ITEM 4.   PURPOSE OF TRANSACTION


         The shares beneficially owned by Mr. Crispin and Ms. Perazzo were
acquired for purposes of investment and not for the purpose of changing the
control of ACY.

         Neither Mr. Crispin nor Ms. Perazzo has any plans which relate to or
would result in:

         (a) the acquisition by any person of additional securities of the
issuer, or the disposition of securities of the issuer; provided, however, that
they reserve the right to acquire additional securities of the issuer or dispose
of securities of the issuer from time to time;

         (b) an extraordinary corporate transaction, such as a merger,
reorganization or liquidation, involving the issuer or any of its subsidiaries;

         (c) a sale or transfer of a material amount of assets of the issuer or
any of its subsidiaries;

         (d) any change in the present board of directors or management of the
issuer, including any plans or proposals to change the number or term of
directors or to fill any existing vacancies on the board;

         (e) any material change in the present capitalization or dividend
policy of the issuer;

         (f) any other material change in the issuer's business or corporate
structure;

         (g) changes in the issuer's charter, bylaws or instruments
corresponding thereto or other actions which may impede the acquisition of
control of the issuer by any person;

         (h) causing a class of securities of the issuer to be delisted from a
national securities exchange or to cease to be authorized to be quoted in an
inter-dealer quotation system of a registered national securities association;

         (i) a class of equity securities of the issuer becoming eligible for
termination of registration pursuant to Section 12(g)(4) of the Act; or

         (j) any action similar to any of those enumerated above.

ITEM 5.   INTEREST IN THE SECURITIES OF THE ISSUER

         (a) Mr. Crispin and Ms. Perazzo together are the beneficial owners of
an aggregate of 315,286 shares of Common Stock of ACY, representing
approximately 20% of the outstanding shares of Common Stock of ACY.

         (b) The shares of Common Stock owned directly by Mr. Crispin and Ms.
Perazzo, are registered jointly in their names, and, as such, they share jointly
the power to vote or to direct the vote of and to dispose or to direct the
disposition of the shares.

Because Mr. Crispin and Ms. Perazzo are each a director, officer, and principal
shareholders and indirect beneficial owner of approximately 60.2% of the Common
Stock of JHC, Mr. Crispin and Ms. Perazzo share jointly, along with other
shareholders, the power to vote or to direct the vote of and to dispose or to
direct the disposition of the shares held by JHC.

Because Mr. Crispin is a director and officer of S-Corp., Mr. Crispin has the
power to vote or to direct the vote of and to dispose or to direct the
disposition of the 82,219 shares of Common Stock held by S-Corp.

         (c) Beneficial ownership of 91 shares was acquired by Mr. Crispin and
Ms. Perazzo pursuant to the Merger Agreement identified in Item 3 of this
Schedule 13D. Beneficial ownership of 84 shares of Common Stock was acquired by
Mr. Crispin and Ms. Perazzo as creditors of CMA Capital Corporation, as
described in Item 3 of this Schedule 13D.

Beneficial ownership of 199,992 shares if ACY Common Stock held by JHC Mr.
Crispin and Ms. Perazzo arises out of their "controlling person" status of
JetFleet Holding Corp, which owns directly 111,692 shares and indirectly 88,300
shares, as identified in Item 3 of this Schedule 13D.

Beneficial ownership of 82,219 shares held by S-Corp. by Mr. Crispin arises out
of his "controlling person" status of S-Corp., as identified in Item 3 of this
Schedule 13D, which owns 82,219 shares of Common Stock.

         (d) To the knowledge and belief of Mr. Crispin and Ms. Perazzo, no
other person is known to have the right to receive or the power to direct the
receipt of dividends from, or the proceeds from the sale of, the 315,286 shares
of Common Stock.

         (e) Not applicable.
