Boeing faces new safety alert over earlier generation of 737s

The US Federal Aviation Administration has urged airlines to inspect so-called door plugs on an earlier version of Boeing 737 airplanes, after one blew out of the side of the newer Max model during an Alaska Airlines flight earlier this month.

(CNN) — The US Federal Aviation Administration has urged airlines to inspect so-called door plugs on an earlier version of Boeing 737 airplanes, after one blew out of the side of the newer Max model during an Alaska Airlines flight earlier this month. The FAA on Sunday said airlines operating the Boeing 737-900ER model should “visually inspect mid-exit door plugs to ensure the door is properly secured,” referring to the panel that plugs the hole where a mid-plane exit would be. “The Boeing 737-900ER is not part of the newer Max fleet but has the same door plug design,” the US aviation regulator added in what is known as a safety alert for operators. Boeing’s shares fell almost 3% in premarket trade Monday. The safety alert on a plane that has been in service for almost two decades will deal a fresh blow to the company, which has faced repeated quality and safety issues with its aircraft in recent years, leading to the long-term grounding of some jets and delayed deliveries of others. The planemaker’s stock has declined about 14% since a door plug on one of its Max 9 airplanes shot out from the side of the fuselage only a few minutes into a flight from Portland, Oregon, to Ontario, California, forcing the pilot to make an emergency landing. In a statement shared with CNN, Boeing said it “fully” supports the FAA and its own customers in the regulator’s latest action.
