AD 2026-04-05 Airworthiness Directives; The Boeing Company Airplanes
Models named: 737-8, 737-9, 737-8200. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to all The Boeing Company Model 737-8, 737-9, and 737-8200 airplanes, certificated in any category.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
Within 30 days after the effective date of this AD, revise the Operating Procedures section of the existing AFM to include the information specified in appendices 1 through 3 of this AD. This may be done by inserting a copy of appendices 1 through 3 of this AD into the AFM.
Unsafe condition
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. The FAA is issuing this AD to address a tripped BAT BUS SECT 2 circuit breaker that could lead to an air conditioning system malfunction causing an uncontrollable, excessively high temperature in the cabin and flight deck. The unsafe condition, if not addressed, could lead to injury or incapacitation of flightcrew and passengers, which could result in the inability to maintain safe flight and landing.
Affected ADs
None.
