The Federal Aviation Administration (FAA) finalized three safety directives for some grounded Boeing Co (NYSE:BA) 777 planes with Raytheon Technologies Corp's (NYSE:RTX) Pratt & Whitney 4000 engines that will allow the planes to return to service, reported Reuters.
The FAA stated that the new directives, proposed in December after three reported in-flight fan blade failures, require enhanced inspections and modifications that will allow Boeing 777-200 and -300 airplanes equipped with those Pratt & Whitney engines to resume flights after being grounded for more than a year.
