FAA proposes AD update for DG-1000T gliders, offers propeller fix as terminating action

The FAA proposes to supersede AD 2025-13-08 for DG Aviation Model DG-1000T gliders, retaining the flight manual revision and Motor INOP placards while introducing an optional propeller adapter ring improvement as terminating action for the operational prohibition. The change reflects a design fix that could restore powerplant operation, but the proposal is not yet final and the fix is optional. This matters for affected operators' compliance and aircraft availability.
