The U.S. Federal Aviation Administration ‌said on Monday (July 27, 2026) that seats ​on hundreds of ⁠Boeing 737 MAX jets registered in the U.S. were incorrectly installed and ‌need to be fixed.

If not, the seats could ‌injure passengers during ‌an emergency ⁠landing.

The FAA’s proposed airworthiness ⁠directive issued on Monday (July 27, 2026) would apply to 453 jets registered in the ​U.S. It ‌did not say whether international operators would also be affected, though they typically follow FAA directives ‌if applicable.

The agency said ​in the airworthiness directive proposal that it received “a ⁠report that certain passenger seat assemblies were not correctly installed ‌in the seat tracks.”

There could be up to 69 track-mounted passenger seat assemblies on each 737 MAX plane and the issue would ‌take an estimated one work-hour to ​fix each assembly, the FAA said.

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

Boeing did not immediately respond ‌to a request for comment.
