AD 2026-14-11 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
This paragraph restates the requirements of paragraph (g) of AD 2026-13-05, with no changes. Within 30 days after February 24, 2026 (the effective date of AD 2026-04-05, Amendment 39-23265 (91 FR 8708, February 24, 2026)), 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. Accomplishing the revision of the existing AFM required by paragraph (h)(1) of this AD terminates the requirement of this paragraph to include the information specified in appendix 1 of this AD in the existing 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 and a determination that there is a formatting error in appendix 5 of AD 2026-13-05 that must be addressed. The FAA is issuing this AD to address a tripped BAT BUS SECT 2 or environmental control systems (ECS) 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
This AD replaces AD 2026-13-05, Amendment 39-23387 (91 FR 39854, July 1, 2026) (AD 2026-13-05).
