Airworthiness Directives; DG Aviation GmbH (Type Certificate Previously Held by DG Flugzeugbau GmbH) Gliders
Transportation Department, Federal Aviation Administration | Proposed Rule | 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.
