Dear Fellow Shareholder,

            The  Wynnefield  Group,  a  long-time  investor  and owner of a 29.7
percent  stake in First  Aviation  Services  Inc.  (FAvS),  is  sending  you the
enclosed  proxy  statement  and GREEN proxy card for the 2004 annual  meeting of
FAvS  shareholders.  As a significant  minority  shareholder whose interests are
aligned with those of other minority shareholders,  we are soliciting proxies in
OPPOSITION TO MANAGEMENT'S DIRECTOR SLATE.

            We have been  dismayed at FAvS'  performance,  performance  that has
resulted in a stock price BELOW BOOK VALUE FOR MORE THAN THREE YEARS. On several
occasions,  we have urged that  management  take  steps that we  believed  would
benefit the company and all its shareholders.  After being repeatedly  rebuffed,
we now have no other choice but to engage in a proxy contest.

            FAvS' CEO and Chairman  (through their investment firm, First Equity
Group Inc.) own over 50 percent of FAvS stock and therefore have complete voting
control in director elections. We believe THE VOICE OF MINORITY SHAREHOLDERS HAS
BEEN IGNORED BY FAVS MANAGEMENT FOR TOO LONG. We believe it is important for ALL
minority shareholders to have a voice in FAvS corporate governance.

            The enclosed proxy  materials and proxy card are our attempt to give
ALL  minority  shareholders  that  voice.  We are  seeking  ONE  board  seat and
proposing  cumulative  voting.  We  urge  you to  read  the  enclosed  materials
carefully,  then VOTE IN FAVOR OF NELSON OBUS FOR  DIRECTOR  and IN FAVOR OF our
shareholder  proposal for  CUMULATIVE  VOTING.  We believe that Nelson Obus 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.

            With management  controlling over 50 percent of FAvS stock, minority
shareholders  cannot win without management  support.  It is therefore important
that as many  shareholders  as  possible  send a message  to the board by voting
"FOR" Nelson Obus and "FOR" our  cumulative  voting  proposal.  We hope that the
board will hear the message and adopt  measures  to give  minority  shareholders
board representation.

            We urge you to return the  enclosed  GREEN proxy card  promptly.  If
your broker or another  nominee  holds your shares,  instruct  them to vote your
shares "FOR" Nelson Obus and "FOR" cumulative voting.

            If you have any  questions or need  assistance in voting your proxy,
please call  Lawrence E. Dennedy or Daniel M.  Sullivan at  MacKenzie  Partners,
Inc., our proxy solicitor, at (800) 322-2885.

                                Very truly yours,

                                /s/ Nelson Obus
