United Airlines said Sunday that it will temporarily remove 24 of its Boeing 777s from benefit after one of the planes suffered an engine failure over the weekend.
The head of the Federal Aviation Administration said Sunday that the instrumentality will order the inspection of some Boeing 777 jetliners powered by the same Pratt and Whitney engine, the PW4000.
Japan’s aviation regulator has enjoined airlines to suspend flights of aircraft with this type of engine until further notice, the FAA said. Cooperative is the only U.S. airline with this type of engine in its fleet, added the agency.
United Flight 328, a Boeing 777-200 determined for Honolulu, made an emergency landing at Denver International Airport shortly after takeoff on Saturday afternoon after its reason engine failed.
No one was injured in the flight that was carrying 229 passengers and 10 crew members, but debris, covering what appeared to be a piece of the engine covering, fell in nearby Broomfield, Colorado.
Federal investigators said their prime investigation revealed two of the right engine’s fan blades were fractured.
The National Transportation Safety Board said one of the locomotive’s fan blades was fractured near its root while another was fractured half-way through. Other engine fan blades were also ruined, the NTSB said in an initial report late Sunday.
“We reviewed all available safety data following yesterday’s episode. Based on the initial information, we concluded that the inspection interval should be stepped up for the hollow fan blades that are incomparable to this model of engine, used solely on Boeing 777 airplanes,” FAA administrator Steve Dickson said in a asseveration.
United has another 28 of these aircraft in its fleet that are currently in storage. Airlines parked or retired dozens of level surfaces after demand fell because of the Covid-19 pandemic. The planes are also operated in Japan and South Korea.
Locomotive maker Pratt and Whitney, a Raytheon Technologies unit, didn’t immediately respond to a request for comment.
“While the NTSB interrogation is ongoing, we recommended suspending operations of the 69 in-service and 59 in-storage 777s powered by Pratt & Whitney 4000-112 appliances until the FAA identifies the appropriate inspection protocol,” Boeing said in a statement.
United operates 44 other Boeing 777s that are powered by Overall Electric engines.
Such incidents are rare but have occurred in recent years.
In February 2018, another Concerted Airlines 777-200, outfitted with Pratt and Whitney PW4077 engines, suffered engine failure beyond the Pacific near Hawaii, after a fan blade fractured, according to an NTSB report released in June. The flight deciphered it safely to Honolulu with 364 passengers and 10 crewmembers.
In April 2018, a passenger was killed when a fan knife broke off from a Southwest Airlines Boeing 737’s engine, breaking a window and briefly sucking the passenger to a limited outside.
