Almost exactly on the one year anniversary of the F-35B probation being rescinded, the aircraft was grounded by the DoD test program office. It faces
a potentially major problem this time. On 16 January, an F-35B at Eglin Air Force Base aborted a test flight on take off, while performing a
conventional take off.
The aircraft in question suffered a failure of a propulsion fueldraulic line, which controls the movement of the actuators for the STOVL exhaust
system. P&W and Rolls-Royce are investigating. Until the investigation is complete all F-35B models at Eglin, Yuma, and the Fort Worth production
facility will remain grounded.
Almost one year ago today (on Jan. 20, 2012), citing the progress the F-35B STOVL (Short take off vertical landing) variant made in 2011,
Secretary of Defense Leon Panetta rescinded probation for the F-35B, about one year ahead of schedule.
The STOVL had come close to be scrapped after technical issues along with massive cost over runs had put the monumentally complex version at risk.
However, when it looked like it had solved all those problems that had jeopardized its survival, the STOVL (Short Take Off Vertical Landing) version
of the F-35 Lightning II 5th generation fighter plane, found another possibly major issue to face.
