US aircraft maker Boeing said it supported decisions by airline regulators in Japan and the United States to suspend operations of 128 of its 777 aircraft powered by Pratt & Whitney 4000-112 engines. A 777 plane had to make an emergency landing in Denver, Colorado, on Saturday after an engine malfunction caused it to dump debris over one of the city’s suburban areas. Federal Aviation Administration Director Steve Dickson said Sunday that “immediate or intensified inspections” of the plane are now required. Boeing BA, + 4.31% said that 69 Boeing 777s powered by the incriminated engine were currently in use and 59 were in storage, due to the reduction in air traffic caused by the COVID-19 pandemic. United Airlines UAL, + 6.83% said hours before Boeing’s press release that it would voluntarily and temporarily recall its own 24 affected aircraft. The forecast: The suspension of the 777s will have a reduced impact on air travel due to the continuing pandemic. But it hits Boeing just as the company was recovering from the 18-month grounding of its 737 jet after two of those planes crashed in October 2019 and March 2019, killing 346 passengers and crew.
