Airworthiness Directives; DG Aviation GmbH (Type Certificate Previously Held by DG Flugzeugbau GmbH) Gliders
By Transportation Department, Federal Aviation Administration · Oct 4, 2026, 11:00 PM CDT
The FAA proposes to supersede Airworthiness Directive (AD) 2025-13-08, which applies to all DG Aviation GmbH Model DG-1000T gliders. AD 2025-13-08 requires revising the glider flight manual and installing "Motor INOP" placards to prohibit operation with the powerplant. Since issuance of AD 2025-13-08, a design improvement to the propeller adapter ring has been developed that is considered terminat

AI analysisMissing context
The excerpt does not provide background on why AD 2025-13-08 was originally issued, any incident history involving the DG‑1000T propeller adapter ring, or details about the specific design improvement that qualifies as a terminating action. It also lacks information on the timeline for compliance, the impact on operators, and any cost or certification considerations.
Important context
Airworthiness Directives are regulatory actions issued by the FAA to correct unsafe conditions in aircraft. A superseding AD replaces an earlier directive, often incorporating new technical solutions or clarifying requirements. The "Motor INOP" placard is a safety measure that prevents operation of a glider with a non‑functional engine, and its removal would indicate that the identified unsafe condition has been resolved.
