FAA investigating loose seats on American Airlines flights

The Federal Aviation Administration is investigating reports of seats on a pair of American Airlines flights containing passengers becoming loose in the middle of a flight.

American Airlines Flights 685 and 443 from Boston and New York's John F. Kennedy International Airport to Miami both made emergency landings over at JFK over the weekend. The FAA said Monday that "preliminary information" indicated that a row of seats on the airplane became loose in the middle of the flight, prompting the emergency landing.

"The airline's initial inspection of each aircraft found other rows of seats that were not properly secured," the FAA said in a statement. "Preliminary information indicates that both aircraft had recently undergone maintenance during which the seats had been removed and re-installed. Including these two airplanes, the airline has taken eight aircraft with similar seat assemblies out of service until they can be inspected."

The FAA said it has increased its surveillance of American Airlines since the company entered bankruptcy proceedings last year.
