Scrutiny of Boeing Co.’s manufacturing quality expanded after federal regulators told airlines to check the door plugs on a second 737 model, where operators have also found issues with fasteners.
The US Federal Aviation Administration recommended that airlines inspect 737-900ER models that use mid-aft plugs of the same type that failed on an Alaska Airlines flight this month. The 737-900ER is an earlier model than the Max 9 used on Flight 1282 on Jan. 5.
