                       WYNNEFIELD URGES FAVS SHAREHOLDERS
                       TO VOTE FOR OBUS, CUMULATIVE VOTING

NEW  YORK,  NY,  June 7,  2004 - The  Wynnefield  Group,  the  largest  minority
shareholder  in First  Aviation  Services Inc.  (NASDAQ:  FAVS),  today mailed a
letter to the  company's  shareholders  urging  their votes for the  election of
Nelson Obus to the FAvS Board,  and for the adoption of cumulative  voting.  The
company's  Annual Meeting of  Shareholders  is scheduled for June 15, 2004. Full
text of the letter follows:


Dear Fellow Shareholder:

My name is Nelson  Obus.  I am  writing  to you on behalf of the  members of the
Wynnefield  Group  ("Wynnefield"),  a long-time  investor and owner of 2,168,444
(29.7%) of the  outstanding  shares of First  Aviation  Services Inc.  ("FAvS").
After  owning  shares  for over six  years,  we are  dismayed  at the  company's
inability to create shareholder value and are running a proxy campaign to ensure
that management hears the voice of minority shareholders.

Even though you and other minority  shareholders  own nearly one-half (48.2%) of
FAvS' common  stock,  OUR VOICES AS  SHAREHOLDERS  ARE BEING IGNORED IN FAVOR OF
FAVS' MAJORITY SHAREHOLDER, AN INVESTMENT COMPANY (FIRST EQUITY) WHOLLY OWNED BY
FAVS' CHAIRMAN AND CEO. FIRST EQUITY BENEFITS FROM BOARD-APPROVED  ADVISORY FEES
($1.4 MILLION IN FOUR YEARS) AND LEASE AND EXPENSE-SHARING PAYMENTS ($140,000 IN
FISCAL 2004) PAID BY FAVS.  Rather then  reinvesting  its cash reserves into the
company, or completing its long stated strategy of growth through  acquisitions,
in 2003 FAvS paid a $7.251  million  special  one-time  dividend,  MOST OF WHICH
BENEFITED FIRST EQUITY AND NOT THE MINORITY SHAREHOLDERS.

To help  protect the rights of minority  shareholders,  and make a statement  to
management  that  minority  shareholders  cannot be  ignored,  WE'RE  SOLICITING
PROXIES FOR MY ELECTION TO THE BOARD OF  DIRECTORS,  AND FOR STEPS TO  IMPLEMENT
CUMULATIVE  VOTING at FAvS' Annual Meeting of shareholders  scheduled to be held
on June 15, 2004.

                  VOTE "FOR" NELSON OBUS AND CUMULATIVE VOTING.
                  SIGN AND RETURN THE ENCLOSED GREEN PROXY CARD
                  AND DISREGARD MANAGEMENT'S WHITE PROXY CARD.

Wynnefield Letter Urges FAvS' Shareholders Vote For Obus, Cumulative Voting -- 2
continued

HERE'S WHAT MANAGEMENT HASN'T TOLD YOU:

  o   FAVS STOCK ACTUALLY UNDERPERFORMED THE RUSSELL 2000 STOCK INDEX AND TWO OF
      THE  THREE  COMPANIES  INCLUDED  IN THE  FAVS'  PEER  GROUP  IN ITS  PROXY
      STATEMENT OVER THE 12-MONTH PERIOD ENDED April 29, 2004. Management boasts
      that FAvS' stock price  increased  36% over that  period.  During the same
      period,  the Russell 2000 Stock Index increased 42%, Aviall,  Inc.'s stock
      price  increased  102%, and AAR Corp.'s stock price  increased  177%. EVEN
      AFTER THE 36%  INCREASE,  FAVS STOCK  ONLY  TRADED  NEAR NET/ NET  WORKING
      CAPITAL  (LIQUIDATION  VALUE) AND BELOW BOOK VALUE.  IS THIS  SOMETHING TO
      BRAG ABOUT?

  o   THIS PROXY CONTEST IS BASED ON THE FAILURE OF THE COMPANY'S MANAGEMENT AND
      BOARD TO CREATE  SHAREHOLDER  VALUE.  Management  accuses  us of running a
      "negative campaign" and "disparagement of incumbent  directors."  However,
      in addition to the stock  performance  cited above,  the company  reported
      AVERAGE ANNUAL LOSSES FROM CONTINUING OPERATIONS OF ($0.12) PER SHARE OVER
      THE LAST FOUR FISCAL YEARS. The current  directors want to keep the status
      quo  intact,  but we think it's time for a  realistic  perspective  on the
      company's LACK OF PERFORMANCE AND SOME MUCH-NEEDED FRESH THINKING.

  o   WE  HAVE  CONSISTENTLY  URGED  MANAGEMENT  TO  COMMIT  TO  DEVELOPING  AND
      IMPLEMENTING  A  BENCHMARKED   BUSINESS  PLAN  THAT  DELIVERS   CONSISTENT
      PROFITABILITY  AND SHAREHOLDER  VALUE WITHIN A SPECIFIED PERIOD OF TIME --
      AND BEEN REBUFFED. If this fails, we would ask the board and management to
      commit  to  explore   transactions   that  would   release  value  to  ALL
      shareholders.

      Management accuses us of pursuing a board seat in an effort to "effectuate
      an exit from FAvS * * * even if the exit  vehicle may be in a  transaction
      or at a  time  that  is not in the  best  interest  of all  shareholders."
      Wynnefield   would  only  seek  a  transaction   that  would  benefit  ALL
      SHAREHOLDERS EQUALLY. With the stock near liquidation value and below book
      value,  IT IS HARD TO IMAGINE A CHANGE THAT WOULD NOT BENEFIT ALL MINORITY
      SHAREHOLDERS.

  o   IF CUMULATIVE VOTING WERE IMPLEMENTED,  MINORITY  SHAREHOLDERS COULD ELECT
      ONLY ONE DIRECTOR A YEAR. WHAT IS MANAGEMENT  AFRAID OF? Management claims
      that our support of cumulative voting reflects a  "self-interested"  focus
      because  we could  elect a director  with the help of  "little  additional
      shareholder support."

      Under cumulative voting, 33.4% of FAvS stock could elect a single director
      at future annual  meetings (when two board seats are up for election).  WE
      THINK IT IS ONLY FAIR THAT MINORITY SHAREHOLDERS SHOULD BE ABLE TO HAVE AT
      LEAST A SINGLE BOARD SEAT.

I WILL BRING TO THE BOARD  NEEDED  FRESH  THINKING  AND A VOICE FOR ALL MINORITY
SHAREHOLDERS.  Cumulative voting will make it possible for minority shareholders
to elect a director.  FAVS'  MANAGEMENT HAS LONG OPPOSED YOUR ABILITY TO ELECT A
SINGLE DIRECTOR OF YOUR CHOOSING.


             PROTECT YOUR INTERESTS AS A FAvS MINORITY SHAREHOLDER.

                  VOTE "FOR" NELSON OBUS AND CUMULATIVE VOTING.
                 SIGN AND RETURN THE ENCLOSED GREEN PROXY CARD.




                                                                        more...




Wynnefield Letter Urges FAvS' Shareholders Vote For Obus, Cumulative Voting -- 3
continued

While  management is spending your money to serve their financial  interests and
maintain  their control of the board,  WE ARE SPENDING OUR OWN MONEY in order to
help  move  FAvS  forward  and  provide   representation  to  ALL  shareholders.
Management  has  repeatedly  stated  that  they will not  permit  us to win.  WE
CONTINUE  TO HOLD OUT  HOPE  THAT,  IF WE  RECEIVE  YOUR  VOTE AND THAT OF OTHER
MINORITY  SHAREHOLDERS,  MANAGEMENT  WILL DO THE  RIGHT  THING AND  SUPPORT  THE
ELECTION OF ONE BOARD MEMBER OF MINORITY SHAREHOLDERS' CHOOSING.
