Full official abstract

This amendment adopts a new airworthiness directive (AD) that applies to certain Alexander Schleicher Segelflugzeugbau (Alexander Schleicher) Model ASK 21 sailplanes. This AD requires removing certain pages from the sailplane flight manual and replacing these pages with new pages having different information regarding spin and stall recovery. This action 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 operators from using inaccurate stall and spin recovery information provided in the sailplane flight manual (SFM), which could result in the inability to recover from a spin or stall during flight.
