Key Takeaways:

  • The NTSB is conducting a two-day hearing into the January 5 door plug detachment from an Alaska Airlines Boeing 737 Max 9, an incident that caused rapid decompression and injured eight of the 177 people aboard.
  • Preliminary NTSB findings indicate that four restraining bolts designed to secure the door plug were missing, an issue preceded by two reported pressurization warnings by flight crews.
  • Boeing, subpoenaed for the hearing, has initiated workplace safety changes, removed officials, announced a new CEO, and was previously sanctioned by the NTSB for releasing nonpublic investigative details.

Starting Tuesday, the National Transportation Safety Board (NTSB) will conduct a two-day hearing in Washington, D.C., to look into the events surrounding the January 5 loss of a door plug from a Boeing 737 Max 9.

The aircraft, operating as Alaska Airlines Flight 1282, had just taken off from Portland International Airport (KPDX) in Oregon, and as it passed through 16,000 feet, the door plug blew off, resulting in rapid decompression. All 177 people on board the aircraft survived, although eight were injured by the loss of pressure that resulted in loose objects and parts of the cabin interior being turned into projectiles.
