The US Federal Aviation Administration (FAA) says seats on hundreds of Boeing 737 MAX aircraft may have been incorrectly installed and require inspection to reduce safety risks. Multiple outlets report that the FAA’s proposed airworthiness directive would apply to 453 Boeing 737 MAX jets registered in the United States. The FAA says the seat assemblies could disengage during conditions such as turbulence or an emergency landing, which it notes could injure passengers and crew or potentially block evacuation routes.

The reporting also indicates that the FAA is making the inspections mandatory through its proposed directive as part of its routine aircraft safety oversight. While one outlet notes that no deadline is specified yet for the directive, overall coverage focuses on the need for corrective action if problems are found. Boeing is described as supporting the FAA’s decision to make the recommendations mandatory. The FAA’s action is framed as preventative, pending the results of inspections and any required repairs.
