Boeing 777s With PW 4000-112 Engines Grounded After Fan Blade Damage Causes Engine Failure

Following the United Airlines flight 328 engine failure involving Pratt & Whitney 4000-112 engine, Boeing Inc. has recommended suspending all 777s powered by the similar PW engines. The grounding of the 777s in operation, including 69 in-service and 59 in-storage, will continue until the U.S. Federal Aviation Administration or FAA identifies the appropriate inspection protocol.
