US plane manufacturer Boeing has recommended grounding all of the 777-model aircraft which have the same type of engine that suffered failure and shed debris over Denver on Saturday.
The US Federal Aviation Administration on Sunday ordered inspections of Boeing 777 planes with Pratt & Whitney PW4000-112 turbines after an uncontained engine failure resulted in an emergency landing of a United flight on Saturday.
Flight 328, carrying 231 passengers, was forced to make an emergency landing at Denver airport. No-one was injured.
The plane manufacturer said that 69 of the 777 jets that are in service are powered by the engine, while 59 such aircraft are in storage.United Airlines (UAL), Korean Air, Asiana Airlines, All Nippon Airways and Japan Airlines (japsy) all use Boeing 777s that feature Pratt & Whitney 4000 engines.
United said Sunday that it would immediately pull 24 planes from flying “out of an abundance of caution. South Korea’s Asiana Airlines, which owns nine of the planes, said it would stop using them, too. The jets are also used by Korean Air. That airline said Monday that it would hold off on making any decision until the country’s transport ministry issued guidance.
