Airworthiness Directives; Boeing Airplanes

What this AD requires

The FAA is adopting a new airworthiness directive (AD) for all Boeing Model B-17E, B-17F, and B-17G airplanes. This AD was prompted by a report indicating that the left front spar lower fitting had completely separated at the wing-to-fuselage joint, and the equivalent joint on the right side of the airplane was cracked. This AD requires inspections of the wing terminal-to-spar chord joints, and repair if necessary. The FAA is issuing this AD to address the unsafe condition on these products.

Which aircraft AD 2023-10-04 applies to

MakesBoeing
ModelsB-17E, B-17F, B-17G, B-17

All airplanes, all serial numbers, certificated in any category.

Whether AD 2023-10-04 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 2023-10-04 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.
