The Federal Aviation Administration (FAA) has announced that it will conduct additional inspections following the United Airlines Boeing 777 crash over Denver, Colorado.
Yesterday, a plane of this model, which took off from Denver to Honolulu, had to return to the airport due to damage to its right engine. The plane landed safely, but the engine crashed into the air and large parts of it fell near residential buildings. No one was injured.
What is the reason for the “breakdown” of the engine
Based on the initial information, we concluded that the inspection should focus on the fan blades, which are unique to this engine model – “Pratt & Whitney 4000-112 (Pratt & Whitney 4000-112, used only for aircraft.” The Boeing 777, the US Federal Aviation Administration said, the BBC reported.
The initial finding by the National Transportation Safety Board (NTSB) was that most of the damage occurred in the right engine, where two fan blades were broken and other blades were affected. The main part of the plane suffered only minor damage.
While the investigation continues, we recommend suspending the operation of 69 aircraft in operation and 59 in stock of the Model 777, powered by Pratt & Whitney 4000-112 engines, the aircraft company said in a statement.
Pratt & Whitney, in turn, said they had sent a team to work with investigators into the cause of the incident.
Airlines stop flights with this model
United Airlines and Japan’s two leading airlines, Japan Airlines (JAL) and All Nippon Airways (ANA), have announced they will stop using their 62 Boeing 777 aircraft.
Boeing said 128 planes with the same engine should be grounded. According to the US Federal Aviation Administration, United is the only airline in the country to fly this Boeing model, and the other aircraft are in Japan and South Korea.
Following the incident, United Airlines said it was voluntarily and temporarily suspending flights of its 24 Pratt and Whitney 4,000 engines.
Japan Airlines and All Nipon Airways grounded 13 and 19 aircraft with such engines, respectively, but avoided flight cancellations using other machines.
