Boeing said on Sunday that all 128 of its 777 jetliners powered by a particular Pratt & Whitney engine model should be grounded worldwide until the Federal Aviation Administration determines the best way to inspect the engines.
The aerospace giant issued its recommendation late Sunday, a day after a 777 operated by United Airlines suffered a dramatic engine failure over Colorado and hours after the head of the F.A.A. said he was requiring “immediate or stepped-up inspections” of planes equipped with the Pratt & Whitney PW4000 family of engines, which are used only on 777s. The vast majority of Boeing 777s are equipped with engines made by GE Aviation.
United, which is the only American carrier affected by the F.A.A. order, said it would temporarily ground the two dozen 777s powered by that Pratt & Whitney model that it had been flying. The National Transportation Safety Board is leading an investigation into the engine failure.
“While the N.T.S.B. investigation is ongoing, we recommended suspending operations of the 69 in-service and 59 in-storage 777s powered by Pratt & Whitney 4000-112 engines until the F.A.A. identifies the appropriate inspection protocol,” Boeing said in a statement.
