Full official abstract
This amendment adopts a new airworthiness directive (AD) that applies to certain Schempp-Hirth (SCHEMPP-HIRTH) Flugzeugbau GmbH Model Duo-Discus gliders. This AD requires you to accomplish a one-time inspection of the bonding of the spar cap and spar web, and repair any defective bonding of the spar cap and spar web. 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 detect and correct failure of the bonding of the spar cap and spar web, which if not detected and corrected, could result in an in-flight failure of the wing.
