After an engine fire, Boeing calls on all airlines to withdraw the affected model 777 with certain propulsion nozzles for the time being. At the weekend, a United Airlines type 777-200 had to land unplanned at Denver Airport because the right engine caught fire and failed and debris fell on the ground.
The US supervision has been more consistent since two crashes of the younger Boeing model 737 MAX with many deaths.
The 26-year-old Boeing 777-200 with 231 passengers and ten crew members was on its way to Honolulu when an engine went up in flames. Nobody was hurt. United is the only American airline that uses the aircraft type. According to the US authorities, other operators are in Japan and South Korea. Boeing announced that 69 such machines were in use. Another 59 are already on the ground due to the corona crisis.
A first check of the engine failure shows “that the inspection intervals for the hollow fan blades should be increased, which are unique to this engine model and are only installed on the 777,” explained FAA boss Steve Dickson. Two fan blades were broken and panels had come loose.
The Japanese Ministry of Transport ordered the companies Japan Airlines (JAL) and the Lufthansa partner airline ANA to decommission their 13 and 19 aircraft, respectively. At the beginning of December, according to the ministry, a 777 from JAL had to turn back due to problems with the left engine. In this case, too, the fan blades were broken.
The supervisory authority in South Korea was waiting for a recommendation from the FAA. However, Korean Air Lines said its six planes currently in use remained on the ground, and ten more have already been temporarily shut down. Asiana Airlines has nine planes and has stated that it will still discuss the consequences with Boeing and the authorities.
