Airworthiness Directives; DG Aviation GmbH (Type Certificate Previously Held by DG Flugzeugbau GmbH) Gliders

What this AD requires

The FAA is adopting a new airworthiness directive (AD) for certain DG Aviation GmbH (type certificate previously held by DG Flugzeugbau GmbH) Model DG-400 gliders and all Model DG-500 Elan Orion, DG-500 Elan Trainer, DG-500/20 Elan, DG-500/22 Elan, DG-500M, DG-500MB, DG-800A, DG-800B, DG-808C, DG-1000M, DG-1000S, and DG-1000T gliders. This AD was prompted by a report of a broken rod end at the upper end of the elevator pushrod in the fin (vertical tail) of a DG Aviation GmbH Model DG-300 glider. Depending on the glider model, this AD requires revising your existing glider maintenance manual to incorporate new procedures for elevator control circuit free play adjustment, performing an operational check of the free play adjustment of the automatic elevator hook-up, accomplishing corrective actions as required, and replacing the elevator pushrod end with a new part. The FAA is issuing this AD to address the unsafe condition on these products.

Whether AD 2024-22321 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 2024-22321 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.
