United expects Boeing 777s to return to sky in Q1 of 202

United said Wednesday its Boeing 777-200 planes equipped with Pratt & Whitney engines are expected to return to service as early as in Q1 2022. The carrier had to ground the wide-body jets after a United flight to Honolulu suffered an engine failure and made an emergency landing in February in Denver. The US FAA ordered immediate inspections of Boeing 777 planes fitted with Pratt & Whitney PW4000 engines after the incident. On Wednesday, the regulator said it is still evaluating the manufacturers' proposed fixes and will not approve them until it is satisfied that they address its safety concerns. "Any work performed on the airplanes prior to that time is subject to being affected by any new Airworthiness Directives," the FAA said. Greg Hart, United's executive vice president, strategy and planning, said the company has not heard from the FAA, but it expects the aircraft to return to service in Q1 next year. "We have been working tirelessly with Boeing, Pratt & Whitney and the FAA over the past six months," he said.<br/>
