Full official abstract

This amendment adopts a new airworthiness directive (AD) that applies to all Glaser-Dirks Flugzeugbau GmbH (Glaser-Dirks) Model DG- 400 gliders. This AD requires replacing the upper rubber shock mounts with mounts made of stainless steel. This AD will also require inspecting the rear plate of the propeller mount for cracks and proper mounting, and replacing or modifying as necessary. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. The actions specified by this AD are intended to prevent failure of the propeller suspension system caused by cracks in the propeller mounts, which could result in loss of the propeller with consequent reduced glider controllability.
