Operators of Boeing passenger airplanes should inspect the seats on certain models, which might have been improperly installed and could prove dangerous in case of an emergency landing, the U.S. aviation authority said.

In a proposed airworthiness directive published Monday, the Federal Aviation Administration said it had received a report that seats on some of the aircraft maker's models were not correctly installed in their seat tracks. The proposed directive would require a "detailed inspection" of the seat installation, the FAA said.

"A track-mounted passenger seat assembly that is installed incorrectly can disengage from the seat tracks if there is an increased load, turbulence, or emergency landing," the FAA said. "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."

Boeing didn't immediately respond to a request for comment.

The proposal concerns three models in the popular 737 family of passenger jets used by major U.S. airlines as well as international customers like Ireland's Ryanair and International Consolidated Airlines, owner of British Airways and Spain's Iberia. In the U.S., the proposed inspection would affect 453 airplanes, incurring a total cost on American operators of around $2.7 million before any re-installation costs, the FAA said.
