PENTAGON GROUNDS F-35 FIGHTERS OVER ENGINE PROBLEM
02:40 23/02/2013
WASHINGTON, February 22 (RIA Novosti) - All flight operations of the
Lockheed Martin F-35 Lightning II fighter planes have been suspended
over an engine problem discovered on one of the aircraft, the US
Department of Defense (DoD) said on Friday.
According to the DoD, a routine engine inspection on Tuesday revealed
a crack on an engine blade of the Pratt & Whitney F135 engine installed
in F-35A aircraft operating at Edwards Air Force Base in California.
"As a precautionary measure, all F-35 flight operations have been
suspended until the investigation is complete," the DoD said in a
statement on its website.
The suspension involves 17 aircraft undergoing testing and 34 in use
for training in Florida and Arizona, and marks another setback for
the Pentagon's most troubled and expensive weapons program.
In January, the Pentagon grounded 25 F-35B planes, the Marine Corps
variant with vertical take-off and landing (VTOL) capability, due to
a manufacturing defect on one of the aircraft.
F-35s have been grounded before over electrical system problems.
The F-35 is currently still being tested, but low-rate initial
production is already underway, with full-rate production due to begin
around 2016. The Pentagon wants to procure a total of 2,443 F-35s.
According to the latest Government Accountability Office report,
the F-35's per unit cost has almost doubled since the inception of
the Joint Strike Fighter program in 2001
