The US company United Airlines, the victim of the accident, the two major Japanese companies, JAL and ANA, as well as South Korean Airlines Asiana Airlines, on Sunday and Monday, announced the shutdown of their devices.
The Federal Aviation Regulatory Authority (FAA) has ordered additional inspections of some Boeing 777s.
The US National Transportation and Safety Board is also investigating the accident in which no one was injured.
“During the investigation, we recommended that we suspend operations of 69 777s in service and 59 aircraft in inventory with Pratt & Whitney 4000-112 engines,” Boeing said in a statement on Sunday.
United said it voluntarily withdrew 24 Boeing 777s from service and expected that “only a few customers will be disturbed.”
Japan Airlines (JAL) and All Nippon Airlines (ANA) also base 13 and 19 aircraft respectively with PW4000 engines, while avoiding flight cancellations thanks to the use of other devices.
Japan’s Transportation Ministry said it ordered stricter engine checks after a JAL 777 taking off from Tokyo Haneda Airport in Naha, Okinawa Island, encountered problems with an “same-family engine” in December.
South Korea’s Ministry of Transport said on Monday that it has no plans to stop the planes yet, but is monitoring the situation.
But Asiana Airlines, South Korea’s second largest carrier, has already made a decision not to use its seven Boeing 777s.
As for Korean Airlines, the nation’s flagship company, which initially told AFP it had installed six 777s equipped with PW4000 engines, it said it was awaiting official guidance from regulators in South Korea.
In a statement posted on Twitter, the Chairman of the US Federal Aviation Regulatory Authority, Steve Dickson, said he has asked his team of aviation safety experts to issue an emergency airworthiness directive that requires immediate or in-depth inspections of Boeing 777 equipped aircraft. With some Pratt & Whitney PW4000 engines.
United Airlines Boeing 777-220, which took off Saturday from Denver (Colorado) to Honolulu (Hawaii) with 231 passengers and 10 crew members on board, had to turn around urgently after a fire broke out in its right-hand reactor.
The plane managed to land safely at the Denver airport, and none of its occupants was injured.
When the Boeing aircraft returned to the airport, bursts of debris, some large, landed in a residential area of Broomfield, a suburb of Denver. Local authorities said that no one was injured on the ground.
The US aircraft manufacturer has run into serious trouble in recent years with its other model, the 737 Max. The plane was prevented from flying in March 2019 after two accidents that killed 346 people, namely the Lion Air accident in Indonesia in October 2018 (189 deaths) and the Ethiopian Airlines accident in March 2019 in Ethiopia (157 people).
After more than 20 months of interdiction, revision of the flight control program, and implementation of new pilot training protocols, the aircraft was again allowed to fly.
The COVID-19 pandemic and its disastrous consequences for international air transport have canceled orders for hundreds of aircraft.
