Pratt & Whitney Canada's PW615F Engine Successfully
Achieves Takeoff Thrust

LONGUEUIL, QUEBEC--Pratt & Whitney Canada Corp. (P&WC) announces
that the first development PW615F turbine engine, selected by
Cessna Aircraft for its new Citation Mustang business jet, has
achieved a first successful run at its rated takeoff thrust of
1,350 pounds. The engine ran for a total of eight hours and has
also completed a number of performance and characterization
tests.

"This first run at full takeoff thrust marks an important
milestone in the PW615F development program," said Maurice
Weinberg, P&WC director, Engine Development Programs - Small
Turbofans. "It clears the way for the first test engine to be
provided to Cessna in early 2004. We are also on track for engine
certification by the end of 2005."

The PW615F is a member of P&WC's newest engine family, the PW600.
Spanning the 900 to 3,000 pound thrust range, the family is
designed to provide operators in the entry-level business jet and
general aviation markets with optimum value and performance with
significantly reduced ownership costs.

An engine demonstrator program involving the PW625F engine, of
which the PW615F is a smaller model, has helped to significantly
reduce development lead-time and risk by validating the concept
design and providing early full and thorough knowledge about the
engine's operational capabilities.

"The 2,500 pound thrust PW625F demonstrator, which completed its
initial flight trials in October 2002 on P&WC's flying test bed,
has provided invaluable lessons that are being applied to all
members of the PW600 family," continued Mr. Weinberg. "This
approach has already enabled us to achieve first run of the
PW615F in an unprecedented 10 months from first design, with
excellent results."

The PW610F engine, another member of the PW600 family that has
been selected by Eclipse Aviation Corp. to power its Eclipse 500
jet, is currently in the design phase. The 900 pound thrust
engine is scheduled to perform its first run in the second
quarter of 2004 leading up to certification in the first quarter
of 2006.

P&WC, based in Longueuil, Quebec, is a world leader in aviation
engines powering business, general aviation and regional
aircraft, and helicopters. The company also offers advanced
engines for industrial applications. P&WC's operations and
service network span the globe. P&WC is a subsidiary of United
