The FAA has proposed replacing an existing safety directive for DG Aviation DG-1000T gliders. The current directive bars powerplant operation through flight-manual changes and cockpit placards. A redesigned propeller adapter ring could provide a route to ending those restrictions. The proposal also calls for inspections and safety pins. It was published October 5 as a proposed rule, rather than a final requirement.
5-Second Takeaway
The FAA has proposed replacing an existing safety directive for DG Aviation DG-1000T gliders.
Why This Matters
The current directive bars powerplant operation through flight-manual changes and cockpit placards. A redesigned propeller adapter ring could provide a route to ending those restrictions.
What Changed
- The proposal concerns DG Aviation GmbH Model DG-1000T gliders.
- It would replace Airworthiness Directive 2025-13-08.
- The existing directive requires flight-manual revisions and Motor INOP placards prohibiting powerplant use.
- The FAA describes an improved propeller adapter ring as an optional modification that could end that prohibition.
- After the specified optional modification, the proposal would allow removal of the Motor INOP placards.
- The proposed directive includes removal, inspection and reinstallation of the adapter disk with safety pins, and restrictions on affected adapter rings.
- The FAA published proposed-rule document 2026-20393 on October 5, 2026.
