A June 13 statement by the JSF Project Office confirmed all the aircraft would be inspected and likely returned to flight on June 14, and that similar faults had been found on three F-35Bs at Yuma, but on no other aircraft.
A report in the Wall Street Journal said the oil warning was traced to the oil flow management unit which provides oil to the engine bearing compartment on the P&W F135 engine.
