March 26, 2004
Burlingame, California






                                 PROXY STATEMENT
                                       FOR
                       2004 ANNUAL MEETING OF STOCKHOLDERS
                                       OF
                                AEROCENTURY CORP.
                          TO BE HELD ON APRIL 29, 2004

This Proxy Statement is furnished in connection with the solicitation by the
Board of Directors of AEROCENTURY CORP. (the "Company") of proxies to be voted
at the 2004 Annual Meeting of Stockholders (the "2004 Annual Meeting" or the
"Annual Meeting"), which will be held at 5:30 p.m. on April 29, 2004, at the
Hiller Aviation Museum, 601 Skyway Road, San Carlos, California, or at any
adjournments or postponements thereof, for the purposes set forth in the
accompanying Notice of 2004 Annual Meeting of Stockholders. This Proxy Statement
and the proxy card were first mailed to stockholders on or about March 27, 2004.
The Company's 2003 Annual Report is being mailed to stockholders concurrently
with this Proxy Statement. The 2003 Annual Report is not to be regarded as proxy
soliciting material or as a communication by means of which any solicitation of
proxies is to be made.

                         VOTING RIGHTS AND SOLICITATION

The close of business on March 1, 2004, was the record date for stockholders
entitled to notice of and to vote at the 2004 Annual Meeting. As of that date,
the Company had 1,543,257 shares of Common Stock, $0.001 par value (the "Common
Stock"), issued and outstanding. The presence at the Annual Meeting of a
majority of the issued and outstanding Common Stock, or 771,629 shares, either
present in person or represented by proxy, will constitute a quorum for the
transaction of business at the Annual Meeting. All of the shares of the
Company's Common Stock outstanding on the record date are entitled to vote at
the 2004 Annual Meeting, and stockholders of record entitled to vote at the
Annual Meeting will have one vote for each share of Common Stock so held with
regard to each matter to be voted upon.

If your shares are registered directly in your name with the Company's transfer
agent, Continental Stock Transfer & Trust Co., you are considered, with respect
to those shares, the "stockholder of record" and these proxy materials are being
sent directly to you by the Company. As the stockholder of record, you have the
right to grant your voting proxy directly to the Company or to vote in person at
the Annual Meeting. The Company has enclosed a proxy card for your use, which
should be returned to the Company.

If your shares are held in a stock brokerage account or by a bank or other
nominee, you are considered the "beneficial owner" of shares held "in street
name" and these proxy materials are being forwarded to you by your broker or
nominee who is considered, with respect to those shares, the stockholder of
record. As the beneficial owner, you have the right to direct your broker on how
to vote and are also invited to attend the Annual Meeting. However, since you
are not the stockholder of record, you may not vote those shares in person at
the Annual Meeting. Your broker or nominee has enclosed a voting instruction
card for your use, which must be returned to your broker or nominee.




Shares of the Company's Common Stock represented by proxies in the accompanying
form that are properly executed and returned to the Company will be voted at the
2004 Annual Meeting in accordance with the instructions of the stockholder of
record contained therein. In the absence of contrary instructions, shares
represented by such proxies will be voted FOR the election of each of the
directors as described herein under "Proposal 1: Election of Directors" and FOR
ratification of the selection of accountants as described herein under "Proposal
2: Ratification of Selection of Independent Auditors." Management does not know
of any matters to be presented at the Annual Meeting other than those set forth
in this Proxy Statement and in the Notice accompanying this Proxy Statement. If
other matters should properly come before the Annual Meeting, the proxy holders
will vote on such matters in accordance with their best judgment. Any
stockholder of record has the right to revoke his or her proxy at any time
before it is voted at the Annual Meeting. Election of directors by stockholders
shall be determined by a plurality of the votes cast by the stockholders of
record entitled to vote at the election present in person or represented by
proxy. Ratification of the selection of accountants shall be determined by a
majority of the votes cast by the stockholders of record entitled to vote at the
Annual Meeting.

Abstentions and broker non-votes are each included in the determination of the
number of shares present for quorum purposes. Abstentions are counted in
tabulations of the votes cast on proposals presented to stockholders and have
the same effect as a negative vote. Broker non-votes are not counted for
purposes of determining whether a proposal has been approved and therefore, do
not have the same effect as votes in opposition to a specific proposal.

The entire cost of soliciting proxies will be borne by the Company. Proxies will
be solicited principally through the use of the mails, but, if deemed desirable,
may be solicited personally or by telephone, telegraph or special letter by
officers and regular Company employees for no additional compensation.
Arrangements may be made with brokerage houses and other custodians, nominees
and fiduciaries to send proxies and proxy material to the beneficial owners of
the Company's Common Stock, and such persons may be reimbursed for their
expenses.

                    HOUSEHOLDING OF ANNUAL MEETING MATERIALS

         Some brokers and other nominee record holders may be participating in
the practice of "householding" proxy statements and annual reports. This means
that only one copy of the proxy statement and annual report may have been sent
to multiple stockholders in a stockholder's household. The Company will promptly
deliver a separate copy of either document to any stockholder who contacts the
Company's Investor Relations Department at (650) 340-1888 requesting such
copies. If a stockholder is receiving multiple copies of the proxy statement and
annual report at the stockholder's household and would like to receive a single
copy of the proxy statement and annual report for a stockholder's household in
the future, stockholders should contact their broker, other nominee record
holder, or the Company's investor relations department to request mailing of a
single copy of the proxy statement and annual report.

Committee meets with the Company's financial management and its independent
auditors to review internal financial information, audit plans and results, and

Executive  Committee  currently  consists of three  directors,  Neal D. Crispin,
Chairman,  Toni M.  Perazzo and Marc J.  Anderson.

The  Company  does not have a formal  Nominating  Committee.  The full  Board of
Directors  reviews  potential  candidates for the Board of Directors.  While the
Board of  Directors  does not have a specific  policy for  considering  nominees
recommended by Stockholders,  this does mean that a recommendation  would not be
considered  if received  from a  Stockholder.  The Board has not yet  considered
adopting  a policy for  considering  nominees  recommended  by  Stockholders  in
addition to those  procedures  already  contained  in the Bylaws of the Company.


Communication   between  Stockholders  and  Directors

The Company's  Board of Directors  currently  does not have a formal process for
Stockholders  to send  communications  to the  Board of  Directors  and does not
believe such  procedures  are  necessary  at this time because it believes  that
informal  communications are sufficient to communicate  questions,  comments and
observations  that could be useful to the Board.

Director  Attendance at Annual Meeting

It is the policy of the Company and Board of Directors that all directors attend
the Annual  Meeting of  Stockholders  and be available  for  questions  from the
Stockholders. Two sitting directors nominated for election were in attendance at
the 2003 Annual Meeting of  Stockholders.  It is anticipated that both directors
nominated for election at the 2004 Annual  Meeting also will be in attendance at
that meeting.

Board Independence

If all of the  nominees  to the Board of  Directors  are  elected,  "independent
directors",  as that term is used in the American Stock Exchange  Company Guide,
will  constitute  50% of the entire Board of Directors of the Company.

Director Compensation

Non-employee members of the Board are each paid an annual fee of $14,000 and are
reimbursed for all reasonable out-of-pocket costs incurred in connection with
their attendance at such meetings. Non-employee members also receive $1,000
annually for each committee membership. Board members who are officers of the
Company do not receive any compensation for Board or committee membership.

Footnotes to Security Ownership:

(1) Except as indicated in the footnotes to this table, the  stockholders  named
in the table are known to the Company to have sole voting and  investment  power
with respect to all shares of Common Stock shown as beneficially  owned by them,
subject  to  community  property  laws  where  applicable.  The number of shares
beneficially  owned includes Common Stock of which such individual has the right
to acquire  beneficial  ownership either currently or within 60 days after March
1, 2004, including, but not limited to, upon the exercise of an option.

(2) For purposes of calculating  percentages,  total outstanding shares consists
of 1,543,257 shares of outstanding  Common Stock,  which excludes shares held by
the Company as treasury stock.

(3) The mailing address is c/o AeroCentury  Corp., 1440 Chapin Avenue Suite 310,
Burlingame, California 94010.

(4) Includes  291,848  shares owned by  corporations  of which Mr. Crispin is an
officer, director and/or principal shareholder.

(5)  Consists  of  shares  owned by  corporations,  of which Ms.  Perazzo  is an
officer,  director  and/or  principal  shareholder,   plus  other  shares  owned
beneficially by Mr. Crispin, spouse of Ms. Perazzo.

(6) Includes 10,200 shares issuable upon exercise of stock bonus plan rights to
receive AeroCentury Common Stock owned by JetFleet Holding Corp ("JHC").

(7)  Consists of 111,692  shares  owned  directly  and 88,300  shares owned by a
wholly-owned subsidiary.

(8)  Consists  of shares  beneficially  owned by  officers  and  directors,  but
excludes  10,200 stock bonus plan shares  described in footnote  (6),  since the
shares  issuable  under this JHC plan are already  counted in the 199,992 shares
beneficially  owned by Mr. Crispin and Ms. Perazzo  indirectly  through JHC, and
therefore  included in the shares counted as beneficially  owned by officers and
directors.








                           RELATED PARTY TRANSACTIONS

Management Agreement. JMC acts as the management company for the Company under
the Management Agreement, dated December 31, 1997, as amended on February 3,
1998, between JMC and the Company. The officers of the Company are also officers
of JMC and two members of JMC's Board of Directors are on the Board of Directors
of the Company.

Under the Management Agreement, the Company pays a monthly management fee to JMC
equal to 0.25% of the net book value of the Company's assets as of the end of
the month for which the fee is due. In addition, JMC may receive an acquisition
fee for locating assets for the Company, provided that the aggregate purchase
price including chargeable acquisition costs and any acquisition fee does not
exceed the fair market value of the asset based on appraisal, and a remarketing
fee in connection with the sale or re-lease of the Company's assets. The
management fees, acquisition fees and remarketing fees may not exceed the
customary and usual fees that would be paid to an unaffiliated party for such
services. During 2003 and 2002, the Company recognized as expense $1,909,850 and
$1,725,330, respectively, of management fees payable to JMC. In connection with
aircraft purchases during 2003 and 2002, the Company paid JMC a total of $0 and
$325,500, respectively, in acquisition fees, which are included in the
capitalized cost of the aircraft. No remarketing fees were accrued to JMC during
2003 or 2002.

Office Space. The Company maintains its principal office at the offices of JMC
at 1440 Chapin Avenue, Suite 310, Burlingame, California, without reimbursement
to JMC.

                      COMPLIANCE WITH SECTION 16(A) OF THE
                         SECURITIES EXCHANGE ACT OF 1934

Section 16(a) of the Securities Exchange Act of 1934, as amended, requires the
Company's directors and executive officers and persons who own more than ten
percent of a registered class of the Company's equity securities, to file with
the Securities and Exchange Commission initial reports of ownership and reports
of changes in ownership of Common Stock and other equity securities of the
Company. Officers, directors and greater than ten percent stockholders are
required by Securities and Exchange Commission regulation to furnish the Company
with copies of all Section 16(a) reports they file.

Based solely upon review of the copies of such reports furnished to the Company
and written representations that no other reports were required, the Company
believes that there was compliance for the fiscal year ended December 31, 2003
with all Section 16(a) filing requirements applicable to the Company's officers,
directors and greater than ten percent beneficial owners.
