Full official abstract

This amendment adopts a new airworthiness directive (AD) that applies to Alexander Schleicher Segelflugzeugbau (Alexander Schleicher) Model ASK-21 sailplanes that do not have a certain automatic elevator connection installed. This AD requires drilling a drainage hole in the elevator pushrod, inspecting the elevator pushrod for corrosion damage, and replacing any elevator pushrod if a certain amount of corrosion damage is found. 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 elevator pushrod caused by corrosion damage, which could result in loss of control of the sailplane.
