The move by Japan Airlines comes a year ahead of schedule and the start of the incident on some flights.
Japan Airlines Co Ltd (fake) says it retired a year earlier than planned from its fleet of 13 Boeing Co7 777 engines with Prot & Whitney engines, the operation was suspended in February after an engine wreck on a United Airlines plane.
The Japanese airline said in a statement on its website on Monday, “The Fake has decided to accelerate the retirement of all P&W-equipped Boeing 7777s by March 2021.
JAL said the new Airbus SE 5050 will be used on the domestic route at Osaka Itami Airport, and that the aircraft will help maintain the frequency of flights that other domestic destinations typically use for domestic routes.
COVID-19 Due to the epidemic, aviation demand is currently lower than normal.
The Japanese carrier had an incident of its own with PW 400 engines in December when a faulty 777 Nahuahn-bound Tokyo-bound aircraft was forced to return to the airport.
The engines are operated by JAL, United Airlines Holdings Inc., ANA Holdings Inc., Korean Airlines Lines Co. Ltd., Asiana Airlines Inc. and Jin Air Co. Ltd.
The U.S. Federal Aviation Administration (FAA) instructed the National Transportation Safety Board in February to immediately inspect 77,777 aircraft, including PW 4,000 engines, before further flight after a cracked fan blade matched a metal exhaust on a United flight.
When metallic fatigue occurs, the crack may gradually grow longer each time the engine is pressed as it starts. Such cracks can linger for years before leading to failure.
The move was prompted by the violent failure of a fan blade on one of the two engines of a United Airlines Boeing Co 777-200. After the 40.5-inch (103-centimeter) blade fell off, it tore off another blade and the structure in front of the engine and threw a suburban rock with metal and other debris.
No one was hit on the ground and the plane landed safely.
In February, a spokesman for Pratt, owned by Raytheon Technologies Corps, said fan blades needed to be sent to repairs in East Hartford, Connecticut, for inspections from Japanese and South Korean airlines.
Analysts said the need for additional checks could speed up the airline’s retirement.
In March 2019, the FAA issued a directive on the same engines after a similar failure of a United jet flying from San Francisco to Hawaii on February 13, 2018.
The fan blades needed to be inspected before reaching a total of seven thousand flights. After these were completed the operators had to repeat the inspection within the next 1000 flights as per the previous instructions.
