Final rule; request for comments.
Summary
The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 737-8, 737-9, and 737-8200 (737 MAX) airplanes; and certain Model 737-800 and 737-900ER series airplanes. This AD was prompted by the determination that the aft cargo compartment fire suppression capability is reduced if the airplane is dispatched or released with failed electronic flow control of air conditioning packs, as is currently allowed by these airplane models' master minimum equipment lists (MMELs). This AD prohibits the carriage of cargo in the aft cargo compartment when the airplane is dispatched or released with failed electronic flow control of air conditioning packs. The FAA is issuing this AD to address the unsafe condition on these products.
