The Alaska Airlines plane that had a door panel fall off midair in January had been scheduled to undergo maintenance later that night, the airline confirmed Tuesday. The incident on Flight 1282, which took off from Portland, Oregon, at 5:07 p.m. Jan. 5, resulted in no serious injuries but sparked an investigation that revealed no bolts were installed on the door plug of the Boeing 737 Max 9 aircraft.
The plane returned to Portland. Oxygen masks deployed as the plane made an emergency return. Boeing has been under scrutiny following the failure of the door plug, which is a panel that seals where a door would be and makes it part of the fuselage. Some Boeing 737 Max 9 planes were temporarily grounded, and Boeing ousted the executive in charge of the 737 Max program. The door plug was later found in the backyard of a Portland-area home. The plane was delivered to Alaska Airlines on Oct.
