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.
Boeing said Tuesday it would review the NTSB's findings "expeditiously" in a statement following the release of the report.
"Whatever final conclusions are reached, Boeing is accountable for what happened. An event like this must not happen on an airplane that leaves our factory," Boeing president and CEO Dave Calhoun said in a statement Tuesday. "We simply must do better for our customers and their passengers."
Boeing said it is taking "immediate action to strengthen quality," including implementing a plan to ensure all mid-exit door plugs on 737-9 s are installed properly and adding inspections further into the supply chain.
Spirit AeroSystems said in a statement Tuesday that it is reviewing the NTSB's report and "remain focused on working closely with Boeing and our regulators on continuous improvement in our processes and meeting the highest standards of safety, quality and reliability."
