The Boeing Company recommended suspending the operation of the 777 airliners with Pratt & Whitney PW4000-112 engines after the incident in the American Denver when part of the skin fell off the plane.
The company noted that 69 such aircraft are in use, and another 59 are in storage. The recommendation is valid until the end of the investigation of the causes of the emergency.
On Saturday, due to an engine malfunction, the wreckage of the skin of a passenger Boeing 777 United Airlines fell in a residential area near the American city of Denver (Colorado), the plane returned safely to the airport shortly after departure. There is no information about injuries on board or as a result of falling debris.
In turn, the National Transportation Safety Board (NTSB) issued a release saying that none of the passengers on United Airlines Flight 328 were injured.
The “right engine failure” occurred shortly after departure from the Denver airport. In general, the plane received “minor damage,” according to preliminary data from experts. Experts found that “two fan blades” in the engine broke; the rest received various injuries. The agency will continue to study this engine, the aircraft itself, and the photos.
The Federal Aviation Administration of the United States has begun checking the 777 series of airliners; the American airline United Airlines has already temporarily stopped flying its 24 aircraft of this type. The Japanese Ministry of Transport, even before the recommendations of Boeing, instructed airlines to suspend the use of Boeing 777 airliners for flights due to the emergency in Colorado. This requirement will apply to Japan Airlines (JAL, 13 aircraft) and ANA (19).
