                    SUPPORT OUR CAMPAIGN TO MOVE FAvS FORWARD

               IT'S TIME FOR FIRST AVIATION TO STOP MAKING EXCUSES

When First Aviation Services Inc. (FAvS) went public in 1997, its IPO prospectus
described A STRATEGY FOR GROWTH that included complementary acquisitions.

After selling its National Airmotive Corporation  subsidiary for $44 million net
in 1999, the company has completed  only one small ($4.6  million)  acquisition.
Then in 2003 the company paid a $7.251 million  dividend,  most of which went to
the  investment  firm First Equity Group Inc.,  which  beneficially  owns 51% of
FAvS' stock.  FAvS also paid First Equity over $1.4  million for  financial  and
investment  advice  during the last four  fiscal  years.  First  Equity is owned
entirely by FAvS' CEO and Chairman.

FAvS  management  CONTINUES  TO  BLAME  INDUSTRY  CONDITIONS  FOR THE  COMPANY'S
PERFORMANCE AND FAILURE TO GROW.

FAvS has reported  AVERAGE ANNUAL LOSSES FROM  CONTINUING  OPERATIONS OF ($0.12)
PER SHARE over the past four fiscal  years and its stock TRADED BELOW BOOK VALUE
FOR MORE THAN THREE FISCAL YEARS.

Meanwhile, FAvS' primary competitor,  AVIALL, INC., has evolved its business and
CONTINUES ITS STRONG RECOVERY SINCE 2001, AS SHOWN BY THE GRAPH ABOVE.

The  Wynnefield  Group owns 29.7% of FAvS stock,  and thinks it's time for FAvS'
management  and majority  shareholder  to STOP MAKING  EXCUSES.  We want them to
START THINKING ABOUT THEIR  RESPONSIBILITY  TO MINORITY  SHAREHOLDERS  to either
make  discernible  progress towards  implementing a profitable  business plan or
begin exploring a transaction that would release value to all shareholders.

Wynnefield is nominating  Nelson Obus for election to the FAvS board as a matter
of principle on behalf of ALL shareholders.

NELSON OBUS WOULD BRING NEW IDEAS TO A COMPANY THAT'S STANDING STILL.
