Federal Aviation Administration (FAA), DOT.
Final rule; request for comments.
The FAA is adopting a new airworthiness directive (AD) for all DG Aviation GmbH (Type Certificate Previously Held by DG Flugzeugbau GmbH) Model DG-1000M gliders. This AD was prompted by reports of engine mount cracking near the propeller head. This AD requires updating the maintenance manual, inspecting the engine mount for cracks, and taking corrective actions if cracks are found. This AD also requires performing a powerplant belt tension inspection and, depending on the results of the inspection, adjusting the belt tension. This AD also requires balancing the propeller assembly and installing a carbon fiber reinforced plastic (CFRP) bracket. This AD also prohibits accomplishing certain maintenance actions in the maintenance manual. The FAA is issuing this AD to address the unsafe condition on these products.
This AD is effective April 20, 2026.
The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of April 20, 2026.
The FAA must receive comments on this AD by May 18, 2026.
