| Dozens of Boeing 777s are out of service |
Japanese and US airlines abandoned dozens of Boeing 777s after severe engine failure on United Airlines Flight 328 that occurred over Denver over the weekend.
The two propeller blades were smashed in the plane's second engine, according to an ongoing investigation by the National Transportation Safety Board.
The Federal Aviation Administration has issued an emergency airworthiness policy requiring an immediate or comprehensive inspection of Boeing 777s powered by Pratt & Whitney PW4000 specialist engines.
Management said this would likely lead to the plane's withdrawal.
According to the Wall Street Journal report, Boeing also urged airlines to halt flight of powered aircraft and recommended the landing of more than 120 aircraft worldwide.
"After the accident, we reviewed all available safety data and based on the initial information we decided to add the hollow propeller specified for this type of aircraft. A Boeing 777 engine should be added to the blade check interval," said Steve Dickson, Federal Aviation Administration agent.
United Airlines announced that it has intentionally discontinued 24 Boeing 777s powered by Pratt & Whitney PW4000 engines and expects a few customers to be uncomfortable.
The Japan Civil Aviation Authority has ordered Japan Airlines and All Nippon Airlines to stop using the same engine aircraft, while Japan Airlines has 14 such aircraft, and All Nippon Airways has a maximum of 19.
No one was injured on United's 328 flight to Honolulu, but an engine failure occurred shortly after takeoff and he returned safely to Denver.
A spokesman for the South Korean Transportation Ministry said before Boeing's statement: It is monitoring the situation but has not taken any action, noting that Korean Airlines has 12 aircraft, half of which are in storage and are being negotiated with the manufacturer. Regulatory authority.
Boeing said: Due to reduced demand due to the coronavirus outbreak, 69 aircraft were in service and 59 aircraft were in stock when airlines landed their aircraft.
The affected 777-200 and 777-300 aircraft are older than newer models and have lower fuel efficiency. Most of the operators take them out of the fleet.
