U.S. officials have recovered a panel that blew off an Alaska Airlines airliner triggering a partial grounding of Boeing’s 737 MAX 9 and sending shares in the planemaker tumbling on Monday.
A door plug tore off on Friday following takeoff from Portland, Oregon, en route to Ontario, California, depressurizing the plane and forcing pilots to turn back.
The plane, with 171 passengers and six crew on board, landed safely.
The U.S. Federal Aviation Administration (FAA) on Saturday ordered the temporary grounding of 171 Boeing MAX 9 jets installed with the same panel, which weighs about 60 pounds (27 kg) and covers an optional exit door.
