TLDR
- The FAA has proposed a new airworthiness directive targeting Boeing 737 MAX passenger seat installations.
- The directive would affect 453 U.S.-registered 737-8, 737-9, and 737-8200 aircraft.
- Some seat assemblies were found to be incorrectly installed in seat tracks, creating a potential safety risk.
- If seats disengage, they could injure passengers or block aisles during an emergency evacuation.
- Total inspection costs are estimated at up to $2.7 million, or $85 per seat assembly.
The FAA has proposed a new airworthiness directive requiring airlines to inspect passenger seat installations on hundreds of Boeing (BA) 737 MAX jets. BA stock was up 0.95% on Monday.
The directive targets 453 U.S.-registered aircraft across the 737-8, 737-9, and 737-8200 variants.
The agency received a report that certain seat assemblies were not correctly fitted into the seat tracks. Incorrectly installed seats could detach under increased load, turbulence, or during an emergency landing.
“This condition, if not addressed, could result in injury to passengers and crew during an emergency landing or could block the aisle, which could slow evacuation,” the FAA warned.
The U.S. FAA is proposing to adopt a new airworthiness directive for select Boeing 737 MAX 8, MAX 9 and high-density MAX 8-200s after learning that certain passenger seat assemblies were not correctly installed in the seat tracks, creating an unsafe condition.

The FAA has not reported any incidents or injuries linked to the issue.
What Airlines Would Be Required to Do
Under the proposed directive, carriers would need to carry out detailed inspections of seat track fittings for every left- and right-side track-mounted passenger seat assembly.
Where problems are found, corrective actions would also be required.
The FAA put the cost of each inspection at $85 per seat assembly, with total costs estimated at up to approximately $2.7 million across all affected aircraft.
Boeing issued guidance to operators on the seat installation issue back in December 2025.
“We support the FAA making that guidance mandatory,” a Boeing spokesperson said.
737 MAX Under the Microscope Again
The 737 MAX has been under close regulatory watch since two fatal crashes in 2018 and 2019 led to a nearly two-year global grounding of the aircraft.
This latest directive adds to a long list of regulatory actions involving the MAX family in the years since.
The FAA said the inspections are designed to confirm that seat assemblies are properly secured to the aircraft’s floor structure.
Passenger seats need to withstand high forces during turbulence and emergency landings, making correct installation in seat tracks a core safety requirement.
The proposed directive is open for public comment before any final ruling is made.
Boeing’s spokesperson confirmed the company is cooperating with the process and backs making the December 2025 guidance a formal requirement.
