United to reactivate PW4000-powered B777s

United does not plan to follow JAL and ANA in retiring its Pratt & Whitney-powered B777-200s and B777-200(ER)s, although it is unable to provide any timeline for the reactivation of the aircraft grounded for the last two months, it said during the quarterly earnings call. "It's just too premature for us to outline what that schedule looks like. We've had really productive collaboration [with Pratt & Whitney, Boeing, and the Federal Aviation Administration] and there's progress. And, we're really looking forward to getting the aircraft back in the air safely," Executive VP and COO Jon Roitman said. United grounded all nineteen B777-200s and thirty-three B777-200(ER)s powered by PW4000 Family engines after the February 20, 2021, incident, when N772UA, operating as flight UA328, suffered an uncontained engine failure and fire on take-off from Denver Int'l, en route to Honolulu. Shortly thereafter, the FAA grounded all B777s powered by these engines for urgent checks.<br/>
