Exam finds multiple cracks in part of United jet's engine
- chmaynard 6y ago"The broken blade on the Pratt & Whitney engine had been used on 2,979 flights since its last inspection in 2016, the NTSB said. At the time, similar blades were required to be inspected every 6,500 flights. The NTSB believes the failed blade then sheared off part of an adjacent fan blade. After the Feb. 20 incident, Pratt & Whitney called for inspections every 1,000 flights." Gosh, I guess everyone underestimated how often we need to inspect the fan blades. I wonder why that happened?
- mannykannot 6y agoA Washington Post report[1] says early signs of cracking, of the blade that failed in the 2018 incident, were dismissed as paint defects. One might wonder if there was a certain amount of wishful thinking involved.
