Full official abstract

This amendment adopts a new airworthiness directive (AD) that applies to all Glaser-Dirks Flugzeugbau GmbH (Glaser-Dirks) Model DG- 500M gliders. This AD requires inspecting the center of gravity (C.G.) tow release cable pulley for correct positioning, and replacing the C.G. tow release cable pulley with one made of aluminum either immediately or eventually depending on the results of the inspection. 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 the C.G. tow release cable from coming off the pulley because of incorrect positioning, which could result in the pilot being unable to release from tow operations.
