Full official abstract

This amendment adopts a new airworthiness directive (AD) that applies to all Alexander Schleicher Segelflugzeugbau (Alexander Schleicher) Model ASK 21 sailplanes that have certain modifications installed. This AD requires changing the sailplane flight manual's weight and balance information. 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 operator from using inaccurate weight and balance information provided in the sailplane flight manual (SFM), which could lead to hazardous flight conditions.
