Airworthiness Directives; The Boeing Company Airplanes

What this AD requires

The FAA is superseding Airworthiness Directive (AD) 2020-24- 04, which applied to all The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. AD 2020-24-04 required revising the existing airplane flight manual (AFM) to incorporate procedures for an approach with a localizer-based navigation aid, monitoring localizer raw data, calling out any significant deviations, and performing an immediate go around under certain conditions. This AD was prompted by the development of a modification to address the previously identified unsafe condition, and the identification of a separate unsafe condition where misleading vertical flight director (FD) guidance can be presented to the flightcrew under certain conditions. This AD continues to require the actions specified in AD 2020-24-04 and requires installing applicable software updates to the flight control module (FCM). Using updated software terminates the retained AFM requirement in this AD. The FAA is issuing this AD to address the unsafe condition on these products.

Whether AD 2023-19-09 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 2023-19-09 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.
