DENVER, KOMPAS.com – Boeing issued no-fly recommendations for more than 120 of its Boeing 777s worldwide.
This policy was put in place following a terrible engine failure on a United Airlines plane in Denver, United States (US). The Boeing 777 aircraft scattered debris all over Denver before making an emergency landing.
Launch Guardian on Sunday night (21/2/2021), Boeing asked airlines with the same type of engine to suspend operations until inspections can be carried out.
Flight 328 United Airlines, flew from Denver International Airport to Honolulu with 231 passengers and 10 crew on Saturday (20/2/2021). Shortly after take-off, one engine died and sparked sparks in the air.
Police in Broomfield, Colorado posted photos of pieces of plane wreckage near homes and other buildings. There were no reports of injuries on the ground or among passengers.
United Airlines said it had temporarily suspended all 24 of its Boeing 777s from active duty.

Meanwhile, the Japanese aviation regulator immediately implemented the same policy. Japan Airlines (JAL) and All Nippon Airways (ANA) were ordered to stop flight 777, which uses Pratt & Whitney PW4000 engines.
Meanwhile, Japanese regulators are also considering whether to take additional action. According to the regulator “Negeri Sakura” ANA operates at least 19 of these types and JAL operates 13 of them.
The aircraft is also used by operators in South Korea.
A spokesman for South Korea’s transport ministry, spoke before Boeing’s statement. He said his party was monitoring the situation, but had not taken any action.
Korean Air Lines claims to have 12 of these types of aircraft, half of which are stored. Consultations with manufacturers and regulators are continuing, but for now this type of aircraft has stopped flying to Japan.
Boeing said a total of 69 of the aircraft were in service and 59 were in storage. Many airlines have parked most of their fleets at this time, due to falling demand related to the coronavirus pandemic.

Boeing’s policy was issued after the US Federal Aviation Administration (FAA) issued an emergency directive on Sunday night (21/2/2021). The FAA says it requires urgent or further inspection of aircraft similar to those involved in the Denver incident.
“We reviewed all available safety data after yesterday’s incident,” the FAA said in a statement from its administrator, Steve Dickson.
“Based on preliminary information, we concluded that the check interval should be increased for the fan blades unique to this engine model. This model is only used on Boeing 777 aircraft.
“This may mean that some planes will be removed from service.”
The 777-200s and 777-300s that were affected were older and more fuel efficient than the newer models. Most of the operators have gradually discontinued this model fleet.
The US National Transportation Safety Administration (NTSB) said a preliminary inspection of the Denver engine showed two fan blades had cracked. The cockpit voice and flight data recorders have been taken to a laboratory in Washington for analysis.

Monday morning (22/2/2021), the Japanese Ministry of Transportation reported that JAL flights from Naha to Tokyo had to return to the airport on December 4 last year. The aircraft suffered damage to the left engine.
The plane is the same age as the United Airlines plane involved in Saturday’s incident, which is 26.
The Guardian said Pratt & Whitney, which is owned by Raytheon Technologies, could not be reached for comment.
