YF-22 TEST POINTS


the decision at a Pentagon briefing,
stating that the F-22/F119 combination
offered ‘clearly better capability with
lower cost, thereby providing the Air
Force with a true best value.’
A formal EMD contract was awarded
that August. Two contracts totalling
$10.91 billion ($9.55 billion for the
airframe and $1.36 billion for engines)
were awarded to the F-22 and F119 teams
— then Lockheed, Boeing and General
Dynamics plus Pratt & Whitney.
The Pratt & Whitney-powered YF-
PAV-2 resumed test flying on October
30, 1991, to support additional handling
tests and some pre-Engineering,
Manufacturing and Demonstration (EMD)
work. It performed 39 flights during this
time before, on April 25, 1992, it crashed
after a control loss during a slow pass
at Edwards. The YF-22 experienced a
series of pilot-induced pitch oscillations

at roughly 40ft above the runway upon
returning to Edwards AFB after a test flight.
With the landing gear retracted, the aircraft
hit the runway and slid 8,000ft. Although
no longer flight worthy, the external
damage was later repaired and the YF-
was flown aboard a C-5 to Griffiss AFB, New
York, where it was used for antenna testing.
PAV-2 had been flown on 70 test flights for
a total of more than 100 hours.
It was a sad final event for the YF-22, but
attention was already turning to the next
phase — EMD. Initially, this was planned
as being for 11 Production Representative
Test Vehicles (PRTVs) including a pair of
F-22B two-seaters, plus one static test and
one fatigue test airframe. Like the YF-
fly-off, the timelines were ambitious,
with the first EMD aircraft expected to
fly in August 1995 and a push for Initial
Operating Capability with the USAF
in 2001.
