What this AD requires

The FAA is adopting a new airworthiness directive (AD) for all Deutsche Aircraft GmbH Model 328-100 airplanes. This AD was prompted by a report of finding cracks in fuselage frames (FR) 24 and FR26. This AD requires a one-time detailed and eddy current inspection of fuselage FR24 and FR26 (left and right sides), performing corrective actions if necessary, and reporting the inspection results, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

Whether AD 2023-25504 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 2023-25504 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.
