## Summary

This document proposes to adopt a new airworthiness directive (AD) that would apply to certain Rolladen Schneider Flugzeugbau GmbH (Rolladen Schneider) Models LS 4 and LS 4a sailplanes. The proposed AD would require you to inspect the airbrake system for damage and proper rigging, with correction, repair, or replacement, as necessary. The proposed AD would also require you to report any damage found to the Federal Aviation Administration (FAA). The proposed AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. The actions specified by the proposed AD are intended to detect and correct damage to the airbrake locking bracket caused by asymmetric loads. This condition could result in the pilot's inability to operate the airbrake controls, with consequent loss of sailplane control.
