              ISS ENDORSES WYNNEFIELD NOMINEE AND CUMULATIVE VOTING
                              FOR FAVS SHAREHOLDERS

  -- INDEPENDENT PROXY VOTING AND CORPORATE GOVERNANCE ADVISORY FIRM RECOMMENDS
                    VOTE FOR WYNNEFIELD'S GREEN PROXY CARD --

NEW  YORK,  NY,  June 8,  2004 - THE  WYNNEFIELD  GROUP,  THE  LARGEST  MINORITY
SHAREHOLDER IN FIRST AVIATION SERVICES INC. (NASDAQ: FAVS), ANNOUNCED TODAY THAT
INSTITUTIONAL  SHAREHOLDER  SERVICES INC.  (ISS) - THE  INFLUENTIAL  INDEPENDENT
PROXY VOTING AND CORPORATE  GOVERNANCE  ADVISORY  FIRM -  RECOMMENDED  THAT FAVS
SHAREHOLDERS  VOTE FOR THE ELECTION OF NELSON  OBUS,  WYNNEFIELD'S  NOMINEE,  AS
DIRECTOR AND FOR THE IMPLEMENTATION OF CUMULATIVE VOTING FOR DIRECTORS.

"We are  gratified  that  ISS - a  leading  independent  proxy  advisory  firm -
recognized that FAvS' minority  shareholders deserve a voice on the board," said
Nelson Obus, the Wynnefield Group nominee to the FAvS board.  "ISS'  conclusions
confirm our findings, as long-time  shareholders of FAvS, that the company needs
a  business  plan to  deliver  profitability  and  shareholder  value - and that
minority shareholders should be given a voice on the FAvS board.

"THIS ANALYSIS  CONFIRMS THAT OVER THE PAST SIX YEARS FAVS HAS FAILED TO DEVELOP
A PROFITABLE BUSINESS STRATEGY,  EXHIBITED UNSATISFACTORY FINANCIAL PERFORMANCE,
HAS MAJOR  DEFICIENCIES IN ITS CORPORATE  GOVERNANCE AND THAT ITS MANAGEMENT AND
INCUMBENT  BOARD HAVE FAILED TO DELIVER  SHAREHOLDER  VALUE.  FAVS CAN NO LONGER
HIDE THESE REAL ISSUES BEHIND PERSONAL ATTACKS ON ME," Mr. Obus concluded.

ISS  CONCLUDED  THAT MR. OBUS'  ELECTION TO THE BAORD IS IN THE BEST INTEREST OF
SHAREHOLDER  VALUE.  ISS SAID:  "WITH POOR  HISTORICAL  SHAREHOLDER  RETURNS,  A
CONTINUING  CONFLICT OF INTEREST DUE TO RELATED  PARTY  TRANSACTIONS  WITH FIRST
EQUITY GROUP,  AND THE MARKET VALUING THE COMPANY NEAR ITS  LIQUIDIATION  VALUE,
THE CIRCUMSTANCES  WARRANT SUPPORT OF THE DISSIDENT NOMINEE.  WE BELIEVE THAT AN
ALTERNATIVE VOICE ON THE BOARD WOULD INCREASE THE ODDS OF MAXIMIZING SHAREHOLDER
VALUE."

ISS' analysis  further  stated that:  "In meeting with Mr. Obus, we believe that
his requests are reasonable.  Asking the board to commit to a business plan with
a targeted  rate of return in order to  benchmark  the  company's  progress  and
performance is reasonable.  Further, the pursuit of strategic  alternatives in a
transaction  is a  reasonable  request if the company is not able to bolster its
performance operationally."

ISS ALSO  FOUND  THAT THE FEES FAVS PAYS TO THE  INVESTMENT  BANK  FIRST  EQUITY
(WHICH IS WHOLLY OWNED BY FAVS'  CHAIRMAN AND ITS CEO)  "REPRESENT A CONFLICT OF
INTEREST" AND THAT THEY ARE "MATERIAL" TO THE COMPANY'S FINANCIAL RESULTS.

Of Mr.  Obus'  qualifications  for  the  board,  ISS  noted  his  background  in
securities  analysis and  portfolio  management,  including his  experience  and
knowledge of the aviation  industry.  It also noted his service as a director on
two other  public  company  boards  and  stated  that,  "THE  SUBSTANTIAL  SHARE
OWNERSHIP  OF THE  WYNNEFIELD  GROUP  ENHANCES THE  CREDIBILITY  OF ITS DIRECTOR
NOMINEE."

                                                                         more...


ISS ENDORSES  WYNNEFIELD  NOMINEE,  CUMULATIVE  VOTING FOR FAVS  SHAREHOLDERS --
CONTINUED                                                                      2

Of the  Wynnefield  Group's  proposal  to  provide  for  CUMULATIVE  VOTING  FOR
DIRECTORS, ISS' report concluded that cumulative voting "is an important tool in
the  protection of  shareholders'  rights" and that,  "IN THIS CASE, THE COMPANY
FAILS TO MEET ALL OF THE  AFOREMENTIONED  CORPORATE  GOVERNANCE AND  PERFORMANCE
CRITERIA. The company's board is classified.  ACCORDINGLY, THE PROPOSAL WARRANTS
SHAREHOLDER SUPPORT."

ISS urged FAvS  shareholders to vote FOR the election of Nelson Obus as director
and FOR the  provision of  cumulative  voting for  directors  on the  Wynnefield
Group's  GREEN proxy card and AGAINST FAvS'  nominees.  The full text of the ISS
analysis is available to ISS members at its website: www.issproxy.com.

The Annual  Meeting of FAvS  shareholders  will be held on June 15, 2004 at 9:30
a.m. local time at the offices of Aerospace Products  International,  Inc., 3778
Distriplex Drive North, Memphis, TN 38118.

The WYNNEFIELD GROUP URGES SHAREHOLDERS TO SIGN, DATE AND RETURN THE GREEN PROXY
CARD VOTING FOR the election of Nelson Obus as director and FOR the provision of
cumulative  voting for directors.  For more  information,  shareholders can call
