Full official abstract

The FAA adopts a new airworthiness directive (AD) for all Schempp-Hirth Flugzeugbau GmbH (Schempp-Hirth) Models Ventus-2a, Ventus-2b, Discus-2a, and Discus-2b sailplanes. This AD requires you to inspect and modify the elevator mass balance. For Models Discus-2a and Discus-2b sailplanes only, this AD also requires you to replace the elevator pushrod. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. We are issuing this AD to detect and correct problems within the sailplane elevator control system before they lead to flutter and sailplane instability. This could eventually result in loss of sailplane control.
