Abstract

The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 737-8, 737-9, and 737-8200 airplanes. This AD was prompted by reports of in-flight events of excessive cabin and flight deck temperatures that could not be controlled by the flightcrew using existing procedures. This AD requires revising the existing airplane flight manual (AFM) to provide the flightcrew with operating procedures (non-normal checklists) if a certain circuit breaker in the standby power control unit (SPCU) trips. The FAA is issuing this AD to address the unsafe condition on these products.
