## Summary

This document proposes to adopt a new airworthiness directive (AD) that would apply to all S.N. CENTRAIR (CENTRAIR) 101 series gliders that have modification 101-24 (major cockpit configuration equipped on all gliders manufactured since 1990) incorporated, and do not have modification 101-21 (minor modifications to this cockpit configuration) incorporated. The proposed AD would require securing an attachment lug to the battery discharge warning device on the glider bracket. The proposed AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for France. The actions specified by the proposed AD are intended to prevent elevator flight control interference caused by an unsecured battery discharge warning device, which could result in reduced or loss of glider control.
