Airworthiness Directives; Burkhart Grob, Luft-und Raumfahrt, GmbH. Model G102 Astir CS Sailplanes

This amendment adopts a new airworthiness directive (AD) that applies to Burkhart Grob, Luft-und Raumfahrt, GmbH. (Grob) Model G102 Astir CS sailplanes. This action requires replacing the elevator control lever with an improved elevator control lever. The discovery of cracks in the elevator control lever during a routine inspection of a Grob Model G102 Astir CS sailplane prompted this action. 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 control lever, which could result in loss of control of the sailplane.
