Airworthiness Directives; The Boeing Company Airplanes

What this AD requires

The FAA is superseding Airworthiness Directive (AD) 2026-13- 05, which applied to all The Boeing Company Model 737-8, 737-9, and 737-8200 airplanes. AD 2026-13-05 required 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 or certain environmental control system (ECS) circuit breakers downstream of the SPCU trip. Since the FAA issued AD 2026-13-05, a formatting error that omitted part of a certain appendix from AD 2026-13-05 was discovered. This AD retains the certain requirements of AD 2026-13-05 and requires revising the existing AFM to include the corrected appendix. The FAA is issuing this AD to address the unsafe condition on these products.

Whether AD 2026-14-11 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.

How AD compliance is recorded

A valid compliance record (14 CFR 43.9) states:

Method of compliance — The specific action taken (inspected, replaced, modified) and to what revision.
Date — When the work was done.
Aircraft time — Total time in service / tach at compliance — how recurring next-due is computed.
Signature & certificate — The A&P/IA who returned it to service, with certificate number.
Is AD 2026-14-11 complied with on your aircraft?

Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.

Applicability is derived from the FAA directive corpus and is advisory, not a legal airworthiness determination. Compliance is established only from an aircraft’s actual records.
