Weeks after a mid-cabin door plug fell off during the ascent of an Alaska Airlines Boeing 737 Max 9, the FAA is recommending flight operators check another model of Boeing airplanes.

On Sunday night, the FAA issued a statement recommending operators of the Boeing 737-900ER "visually inspect mid-exit door plugs to ensure the door is properly secured." In a statement late Sunday night, Boeing said it fully supports "the FAA and our customers in this action."

The 737-900ER has the same door plug design as the 737 Max 9.

According to the FAA’s safety alert, some operators that were conducting additional inspections on their 737-900ER mid-exit door plugs "noted findings with bolts during the maintenance inspections."
