Airworthiness Directives; Schempp-Hirth Flugzeugbau GmbH Gliders

The FAA is correcting an airworthiness directive (AD) that published in the Federal Register. That AD applies to certain Schempp- Hirth Flugzeugbau GmbH Models Duo Discus and Duo Discus T gliders. The Model Duo Discus gliders were incorrectly referenced as powered sailplanes in the Applicability section. This document corrects that error and refers to both models as just gliders as in previous ADs. In all other respects, the original document remains the same; however we are publishing the entire rule in the Federal Register.
