WASHINGTON (Reuters) - A United Airlines Boeing 777 plane with a Pratt & Whitney engine that failed on Feb. 20 had flown fewer than half the flights allowed by U.S. regulators between fan blade inspections, the National Transportation Safety Board (NTSB) confirmed on Friday.

The Boeing Co 777 plane had flown 2,979 cycles before its last inspection in 2016. At the time of the incident, checks were required every 6,500 cycles mandated after a separate United engine failure in 2018. A cycle refers to one take-off and landing.
