The US Federal Aviation âAdministration said on Monday that seats on hundreds of Boeing 737 âMAX jets registered in the US may require inspections in case they were incorrectly installed and needed to be fixed.

If not, the seats could injure passengers and crew members during âan emergency landing or block the aisle and slow an evacuation, the âagency said.

The FAA's proposed airworthiness directive issued on Monday would apply â to 453 jets registered in the US. The agency only has jurisdiction over âUS airlines, but foreign regulators typically follow FAA directives if applicable.

The proposed directive âcomes as Boeing works to improve its production quality and boost output under CEO Kelly Ortberg. Production quality problems were revealed in early 2024 when a door plug panel blew out of âa nearly new Alaska Air 737 MAX in flight.

The FAA said in âthe airworthiness directive proposal that it received a report that some passenger seat assemblies were not âcorrectly â installed in the seat tracks.

That meant the assemblies could disengage from the seat tracks if there was an increased load, turbulence or an emergency landing, the FAA said.

"This condition, if not addressed, could result in injury to passengers and crew âduring an emergency âlanding or could â block the aisle, which could slow evacuation," it added.

There could be up to 69 track-mounted passenger seat assemblies on each â737 MAX plane and the issue would take an estimated âone work â hour to fix each assembly and requires no parts to do so, the FAA said.

It did not say how quickly airlines would need to correct the issue.

A â Boeing spokesperson âsaid the planemaker issued guidance to operators about âthe issue in December 2025.

"We support the FAA making that guidance mandatory," the spokesperson said in âan email.
