Lessons Learned: FAA Issues Emergency AD, 737-9


Boeing 737-9 planes are required by the FAA to undergo immediate, emergency inspection.

On January 6, 2024, the FAA issued emergency Airworthiness Directive (AD) 2024-02-51 to be sent to all owners of Boeing 737-9 airplanes.

This FAA statement reads,

“This emergency AD was prompted by a report of an in-flight departure of a mid cabin door plug, which resulted in a rapid decompression of the airplane. The FAA is issuing this AD to address the potential in-flight loss of a mid cabin door plug, which could result in injury to passengers and crew, the door impacting the airplane, and/or loss of control of the airplane.”

And the determination of the FAA states: “The FAA is issuing this AD because the agency has determined the unsafe condition described previously is likely to exist or develop in other products of the same type design.”

The requirements of the FAA AD are: “This AD prohibits further flight of affected airplanes, until the airplane is inspected and all applicable corrective actions have been performed using a method approved by the Manager,AIR-520, Continued Operational Safety Branch, FAA.”
