said in a statement Sunday that based on an initial review of safety data, inspectors "concluded that the inspection interval should be stepped up for the hollow fan blades that are unique to this model of engine, used solely on Boeing 777 airplanes."Dickson said that would likely mean some planes would be grounded — and Boeing said they should be until the FAA sets up an inspection regime.
Japan ordered the planes out of service, according to the financial newspaper Nikkei, while saying that an engine in the same family suffered trouble in December.Boeing said there were 69 777s with the Pratt & Whitney 4000-112 engines in service and another 59 in storage.RELATED: LISTEN: United pilot called 'mayday, mayday' amid engine failure after.
