US federal regulators have temporarily grounded some Boeing 737 Max planes in American airspace after a section of an Alaska Airlines jet blew out in mid-air.
The emergency directive from the US Federal Aviation Administration affects about 171 jets worldwide. Carriers will need to inspect aircraft before further flight, a process that takes four to eight hours per plane, according to the directive.
“The FAA is requiring immediate inspections of certain Boeing 737 MAX 9 planes before they can return to flight,” FAA Administrator Mike Whitaker said. “Safety will continue to drive our decision-making as we assist the [National Transportation Safety Board’s] investigation into Alaska Airlines Flight 1282.”
