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.

- tec123Does that are trying to sink Russian airplanes and work sector.11:11, 23/02/2013In my post yesterday I said the West don't make dangerous statements on their aircraft no matter what faults the plane has.
But with Russian airplanes the Russian media is quick to add insult to injury.
It is the stark difference between Russian and the West reporting on protecting their interest and work sector, Areoflot and some corrupt people inside Russia should learn.
