Alaska Airlines 1282: the door plug that came off in flight

A panel covering an unused exit separated from a nearly new Boeing 737-9 shortly after takeoff from Portland. Everyone survived, and the investigation traced it to four bolts that were never put back at the factory.

What happened

About six minutes after leaving Portland International Airport for Ontario, California, Alaska Airlines flight 1282 was climbing through about 14,830 feet when a mid-exit door plug — a panel that fills an extra emergency-exit opening that this airline's seating layout doesn't need — separated from the left side of the cabin. The cabin depressurized rapidly.1

The pilots and flight attendants ran their emergency procedures, and the airplane returned to Portland and landed safely. Seven passengers and one flight attendant had minor injuries; everyone else on board was uninjured.1

What the investigation found

  • The plug was found in a Portland neighborhood two days later. Damage marks showed that the four bolts meant to stop it moving were missing before the flight — and the unsecured plug had crept upward a little on earlier flights until it came free.3
  • The airplane had been delivered just three months earlier. At Boeing's factory in Renton, Washington, the plug had been opened on Sept. 18, 2023 for rivet repair work and closed the next day without the required paperwork — so no quality inspection of the closure took place.3
  • The NTSB's probable cause: Boeing's failure to provide adequate training, guidance and oversight so factory workers could reliably follow its parts-removal process. Contributing: the FAA's ineffective oversight, which didn't ensure Boeing fixed repeated problems with that process.1

How rare is this?

The NTSB traced this event to a breakdown in a factory process and in oversight of that process — the kind of systemic finding that leads to fixes across a whole production line. For context on just how uncommon serious airline accidents are overall, see the box on this page.

What changed

  • The day after, the FAA grounded Boeing 737-9s fitted with this type of door plug and required detailed inspections before they could fly again.4
  • On Jan. 24, 2024 the FAA barred Boeing from expanding 737 MAX production until it was satisfied with Boeing's quality control.5
  • The NTSB's final report also recommended better hands-on oxygen-mask training for crews, longer (25-hour) cockpit voice recorders, and reiterated that the safest place for children under 2 is their own seat in an approved child restraint.2

The reassuring part: a serious structural event happened at altitude, and the airplane, crew and procedures worked as designed to bring everyone home. Seat belts matter here too — passengers in their seats with belts fastened were kept safe.
