Boeing 737 MAX 9: Panel Detachment During Flight

As Alaska Airlines Flight 1282 reached 16,000 feet, a panel on the left side of the Boeing 737 MAX 9 tore off, creating a refrigerator-sized hole. The panel, a plug used in place of an additional emergency exit, is present on some MAX 9s, depending on seating configurations.

Purpose of the Panel

The Boeing 737 MAX 9, Boeing’s largest single-aisle plane, can accommodate up to 220 passengers. The optional extra door or panel allows for the approved number of evacuation paths when carriers opt for maximum seating capacity.

Panel Installation and Production

Kansas-based Spirit AeroSystems manufactures the fuselage for Boeing 737s, including the plug doors on the MAX 9. The installation process involves both Spirit’s plant in Kansas and Boeing’s factory in Washington. The fuselage is sent semi-rigged, and Boeing completes the installation, including pressurization tests to ensure safety.

FAA Grounding Order and Inspection Challenges

Following the incident, the Federal Aviation Administration (FAA) ordered the temporary grounding of 171 Boeing jets with the same panel. However, challenges in finalizing inspection criteria and coordination with Boeing have caused delays, affecting airlines such as Alaska and United.

Impact on Airlines and Passengers

Alaska Airlines and United Airlines have grounded their fleets of affected Boeing 737 MAX 9s, leading to flight cancellations and disruptions for thousands of passengers. The grounding will continue until the FAA is satisfied with the safety of these aircraft.

Search for Missing Panel and Investigation

The National Transportation Safety Board (NTSB) is investigating the incident, and efforts are underway to locate the missing panel, which likely landed in the western suburbs of Portland. Boeing CEO Dave Calhoun emphasized transparency in addressing the causes of the event.


The recent panel detachment incident adds another layer of scrutiny to Boeing’s 737 MAX series, raising questions about safety measures and inspection protocols. As the investigation unfolds, airlines await guidance from regulatory authorities, and passengers face disruptions amid the temporary grounding of affected aircraft. Boeing’s response and the outcomes of the investigation will have broader implications for the aviation industry’s commitment to passenger safety.
