What the agency says
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 terminating action for the operational prohibition of AD 2025-13-08. This proposed AD would retain the requirement to revise the flight manual, would provide an optional terminating action for the retained actions by incorporating a specified modification, would allow removal of the "Motor INOP" placards following accomplishment of that optional terminating action, and would require removal, inspection, and reinstallation of the propeller adapter disk, including installation of safety pins. This proposed AD would also prohibit the installation of affected propeller adapter rings. The FAA is proposing this AD to address the unsafe condition on these products.
