The U.S. National Transportation Safety Board will hold a hearing on Tuesday to determine the probable cause of a mid-air cabin panel blowout of a new Boeing 737 MAX 9 flight in January 2024 that spun the planemaker into a major crisis.

Aircraft manufacturer Boeing Co. (NYSE:BA) is set to be probed for its role in last year's Alaska Air Group Inc. (NYSE:ALK) Flight 1282 incident involving a sudden loss of pressure in the aircraft's fuselage.

The nation's top safety investigators concluded that a lack of basic safety processes at Boeing, coupled with an inexperienced workforce, contributed to the door plug blowout in January 2024.
