S10 FAA AD Propeller Forks

97-CE-128-AD | 98-15-24

This amendment adopts a new airworthiness directive (AD) that applies to certain Stemme
GmbH & Co. KG (Stemme) Model S10-V sailplanes. This AD requires replacing the propeller blade suspension forks with parts of improved design. 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 propeller suspension fork failure caused by design deficiency, which could result in loss of a propeller blade and loss of sailplane controllability
