On 20 February 2021, a PW4077-powered Boeing 777-200 was climbing through 12,500 feet after takeoff from Denver when there was a sudden uncontained failure of the right engine. The associated fire did not fully extinguish in response to the prescribed non-normal procedure and on completion of a return to land, it was fully extinguished before the aircraft could be towed in for passenger disembarkation. The Investigation has already established that the failure originated in a single fan blade within which internal fatigue cracking had been initiated. All operators of 777s powered by PW4000 series engines have grounded their fleets indefinitely.
