The door plug fell off shortly after Alaska Flight 1282 took off on Jan. 5.
Four bolts designed to prevent the door plug from falling off the Boeing 737 Max 9 plane were missing before the plug blew off during an Alaska Airlines flight last month, the National Transportation Safety Board said in a preliminary report of the incident released on Tuesday.
Boeing records reviewed by the NTSB showed that damaged rivets on the edge frame forward of the plug were replaced by Spirit AeroSystems employees at Boeing's factory in Renton, Washington, on Sept. 19, 2023, according to the agency's report. Boeing had to open the plug by removing the two vertical movement arrestor bolts and two upper guide track bolts for the rivets to be replaced, but photo documentation obtained from Boeing showed evidence that the plug was closed with no bolts in three visible locations, according to the NTSB report.
