March 13, 2024
Aug. 6 and 7 hearing will assist in obtaining information necessary to determine the facts, circumstances, and probable cause.

The National Transportation Safety Board will hold a hearing Aug. 6 and 7 on its investigation into how and why a door plug departed from a Boeing 737-9 MAX passenger jet during flight.

The NTSB conducts an investigative hearing​ to assist in obtaining information necessary to determine the facts, circumstances, and probable cause of the transportation accident or incident under investigation and to make recommendations to improve transportation safety. While the investigative hearing is open to the public, only NTSB board members, investigators, scheduled witnesses and parties to the hearing are allowed to participate. The hearing will also be livestreamed. The location and other details about the hearing will be announced in the coming weeks.

The accident occurred Jan. 5, when a left mid exit door plug departed the airplane, operated as Alaska Airlines Flight 1282, at an altitude of about 16,000 feet shortly after departing Portland, Oregon, on a flight destined for Ontario, California. Following the loss of the door plug, which led to a rapid decompression, the flight crew returned to Portland where the airplane landed safely. Of the 171 passengers and six crewmembers onboard, eight reported minor injuries.
