AD 99-09-07 64 FR 20152

This amendment adopts a new airworthiness directive (AD) that applies 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. This AD requires installing an attachment lug to the supporting bracket in order to secure the battery discharge warning device. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for France. The actions specified by this 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.
