Following Japan’s grounding of all Boeing 777s equipped with Pratt & Whitney PW4000-112  turbofans, the U.S. FAA late Sunday said it would issue an emergency airworthiness directive requiring immediate or “stepped up” inspections of the airplanes in reaction to a major engine failure aboard a United Airlines 777-200 on Saturday. The order came as United Airlines, the only U.S. operator of the airplanes in question, said it had grounded its fleet of 24 after consultations with Boeing and the FAA.
