Pentagon suspends all F-35 flights due to crack in engine blade
WASHINGTON (REUTERS) - The Pentagon on Friday suspended the flights of all F-35 fighter planes after a routine inspection revealed a crack on a turbine blade in the jet engine of an F-35 test aircraft in California.
It was the second grounding of the warplane in two months.
The F-35 program office said it was too early to know if this was a fleet-wide issue, but it was suspending all flights until an investigation was completed.
It said it was working closely with Pratt & Whitney, the United Technologies Corp unit that builds the engine, and Lockheed Martin Corp, the prime contractor for the radar-evading warplane, to ensure the integrity of the engine and return the F-35 fleet to flight as soon as possible.
