On February 20, in the United States, a Boeing 777 jet caught fire and its debris fell on residential buildings. Following the incident, the US Federal Aviation Administration and the US National Transportation Safety Board began scrutiny.
In the US, all Boeing 777s powered by Pratt & Whitney 4000-112 engines will be checked after one of them recently caught fire shortly after departure and the plane began to fall apart in the air. About it it says in a statement from the U.S. Federal Aviation Administration on Twitter.
“We reviewed all the available safety data from yesterday’s incident. Based on initial information, we have concluded that the inspection time for hollow fan blades, which are unique to this engine model, used exclusively on Boeing 777 aircraft, should be increased,” said the head Aviation Administration Steve Dixon.
The statement also states the need to decommission a number of Boeing 777 aircraft powered by the Pratt & Whitney 4000-112 engine.
The US National Transportation Safety Board has already taken up the investigation. A preliminary inspection of the stricken aircraft’s engine showed that two fan blades were broken and the rest damaged, CNN reported. Sources of journalists noted that, probably, one blade came off, hitting another.
Boeing supported the decision to temporarily decommission this series of aircraft.
“While the investigation by the National Transportation Safety Council continues, we have recommended that 69 in service and 59 in storage Boeing 777s with Pratt & Whitney 4000-112 engines be suspended until the FAO determines the appropriate inspection protocol,” the report says. company message.
The incident, due to which the aircraft checks began, happened on February 20. A United Airlines plane took off from Denver for Honolulu, but soon after takeoff, its engine caught fire. The plane returned to the airport, none of the passengers was injured, but engine wreckage fell on residential buildings.
