The unprecedented blow to air transport was not enough, due to a pandemic. Now, the American aeronautical company Boeing is requesting the anchoring of more than 120 of its 777 type aircraft, worldwide, after the recent air tragedy with the flight of United Airlines, on Saturday, in Denver, USA.
Okay let’s talk engine design: If the forward fan loses a blade, the brown casing that surrounds it is designed to catch any debris without a breach. If parts of the core fail, the casing isn’t designed for containment because of the incredible internal energy. https://t.co/cLx1Etza1q

To be precise, it requests inspections on all its aircraft powered by Raytheon Technologies Pratt & Whitney 4000 engines. The same type, that is, with those brought by the United Airlines plane, whose right engine exploded, shortly after the Boeing 777 had taken off from Denver airport, bound for Honolulu, with 241 passengers.
No miracles were reported, neither among the passengers, nor on the ground, as in the area στην it rained engine debris. Keeping his composure, the pilot of Flight 328 managed to land the aircraft safely back at Denver International Airport.
“It’s got a blown engine! Oh no!” Video shows a United Airlines jet leaving a trail of smoke after its right engine failed Saturday, dumping large pieces of debris on Denver-area neighborhoods. The pilot issued a mayday call and the plane landed safely. https://t.co/VAadvhvAFA

Two days after the incident and on the instructions of the US Federal Aviation Administration (FAA), United Airlines announced the temporary suspension of all 24 Boeing 777 aircraft in its fleet with this type of engine.
Similar measures have already been announced by airlines in Japan, following the recommendation of the competent authorities.
“Based on the initial information, we conclude that the interval between inspections should be accelerated with respect to the hollow blades in the turbines, which are unique to this engine model and are used exclusively on the Boeing 777,” an FAA spokesman said. “This probably means that some aircraft will be taken out of service.”
This is another blow to Boeing, the mediator of the pandemic, and while the resumption of flights of the controversial Boeing 737 MAX has not yet begun.
This type of aircraft has been redesigned in the last two years, in the “shadow” of two large-scale plane crashes and its stagnation for many months, due to serious deficiencies and malfunctions in the MCAS flight system. A case that hit the credibility of Boeing, but also of the FAA, for “gaps” in the surveillance mechanism of the American aeronautical giant.
