Airworthiness Directive 2026-06534
one-timeAirworthiness 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 all DG Aviation GmbH (Type Certificate Previously Held by DG Flugzeugbau GmbH) Model DG-1000M gliders. This AD was prompted by reports of engine mount cracking near the propeller head. This AD requires updating the maintenance manual, inspecting the engine mount for cracks, and taking corrective actions if cracks are found. This AD also requires performing a powerplant belt tension inspection and, depending on the results of the inspection, adjusting the belt tension. This AD also requires balancing the propeller assembly and installing a carbon fiber reinforced plastic (CFRP) bracket. This AD also prohibits accomplishing certain maintenance actions in the maintenance manual. The FAA is issuing this AD to address the unsafe condition on these products.
Which aircraft AD 2026-06534 applies to
Type certificate previously held by DG Flugzeugbau GmbH. Applies to all serial numbers of Model DG-1000M gliders, certificated in any category.
Whether AD 2026-06534 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:
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.
