The US Federal Aviation Regulatory Authority (FAA) ordered additional inspections on some Boeing 777-type commercial aircraft on Sunday.
“After consulting my team of aviation safety experts about yesterday’s engine failure [samedi] aboard a Boeing 777 aircraft in Denver, Colorado, I asked them to issue an Emergency Airworthiness Directive that would require immediate or thorough inspections of Boeing 777 aircraft equipped with certain Pratt & Whitney PW4000 engines, ”wrote FAA official Steve Dickson in a statement posted to Twitter. “This will likely mean that some planes will be taken out of service.”
A United Airlines Boeing 777-220, which had taken off Saturday from Denver (Colorado) for Honolulu (Hawaii) with 231 passengers and 10 crew members, had to turn around urgently after the fire in his right reactor. The aircraft was able to land safely at Denver Airport and none of its occupants were injured.
A video taken by a passenger on flight UA328 shows the right engine of the plane in flames and shows that the damaged engine fairing is completely missing. As the Boeing returned to the airport, a shower of debris, some large, fell in a residential area in Broomfield, a suburb of Denver. No one was injured on the ground, according to local authorities.
“The interval between inspections should be shortened”
Steve Dickson said a preliminary review of safety data revealed the need for additional fan blade checks for the affected reactor type.
“Based on the initial information, we concluded that the interval between inspections should be shortened for the hollow fan blades, which exist only on this type of engine, used only on Boeing 777s,” said the official. of the FAA.
Steve Dickson added that FAA officials were meeting with representatives from Pratt & Withney and Boeing on Sunday evening.
The 737 MAX crisis in mind
The American aircraft manufacturer has had a serious problem in recent years with another of its models, the 737 MAX. The plane was banned from flying in March 2019 after two accidents that killed 346, that of Lion Air in Indonesia in October 2018 (189 dead) and that of Ethiopian Airlines in March 2019 in Ethiopia (157 dead).
During the two accidents, it was after receiving erroneous information from one of the two AOA angle of attack sensors, indicating that the aircraft was stalled, that the flight control software, the MCAS, had run away despite the pilots’ efforts to disable it and had the aircraft pitched down, causing it to fall. As a result, Boeing had to modify the flight control software and put in place new pilot training protocols before the aircraft was allowed to fly again, after more than 20 months of ban.

The resumption of commercial flights of the Boeing 737 MAX took place from December 2020, first in Brazil, then in the United States and Canada. The first commercial flight in Europe, under the colors of the Belgian company TUI fly, took place on Wednesday February 17 between Brussels and Alicante then Malaga, in Spain.
