FAA urges inspections to door plugs on another Boeing 737 jet

The Federal Aviation Administration is urging airlines to inspect door panels on another type of Boeing 737 jet, weeks after a door plug blew out mid-air on an Alaska Airlines flight.

In a statement issued Sunday, the FAA said it is recommending that airlines that operate Boeing 737-900ER jets "visually inspect mid-exit door plugs to ensure the door is properly secured." 

While the Boeing 737-900ER has been in use for nearly two decades, the FAA said it has the same door plug design as the Boeing 737 Max 9 jet involved in the Alaska Airlines' mid-air incident.
