Inadequate inspections by Pratt & Whitney were partly responsible for a midflight breakdown of a jet engine that showered a Colorado town with metal 2½ years ago, aviation-safety authorities concluded Friday.
The engine failure on the Honolulu-bound United Airlines Boeing 777 on Feb. 20, 2021, was caused by a fan blade that broke about five minutes after the plane took off, damaging the engine covering and causing it to rip away. The plane’s engine caught fire, but the flight returned to Denver and landed safely.
A 2016 inspection misdiagnosed early signs of metal fatigue forming that should have prompted a second inspection or further review, the National Transportation Safety Board wrote in a report released Friday.
