Airworthiness Directives; VALENTIN GmbH Model 17E Sailplanes

This amendment adopts a new airworthiness directive (AD) that applies to all VALENTIN GmbH (Valentin) Model 17E sailplanes. This AD requires you to inspect for, and correct, cracked or improperly installed central wing bolts; install a stronger central bolt if not already installed; and inspect for, and replace, problem telescopic rods. 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 correct improperly installed or cracked central bolts and damaged, deformed, or loose telescopic rods. This condition, if not corrected, could cause the wing to separate from the sailplane, which could cause result in control of the sailplane.
