Boeing has recommended that airlines ground all 777s with the type of engine that blew apart after takeoff from Denver this weekend, and most carriers that fly those planes said they would temporarily pull them from service.
The U.S. Federal Aviation Administration ordered United Airlines to step up inspections of the aircraft after one of its flights made an emergency landing at Denver International Airport Saturday as pieces of the casing of the engine, a Pratt & Whitney PW4000, rained down on suburban neighbourhoods. None of the 231 passengers or 10 crew were hurt, and the flight landed safely, authorities said. United is among the carriers that has grounded the planes.
