Airworthiness Directives; Rolladen Schneider Flugzeugbau GmbH Models LS 3, LS 4, and LS 6c Sailplanes

This amendment adopts a new airworthiness directive (AD) that applies to all Rolladen Schneider Flugzeugbau GmbH (Rolladen Schneider) Models LS 3, LS 4, and LS 6c sailplanes. This AD requires you to inspect the airbrake levers in the wing for lower end corrosion and for play in flight direction when fully extended and retracting under load; replace the bearings if there is jamming under load or if corrosion is found; and adjust the lower lever member (only for the Model LS 3). This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. The actions specified by this AD are intended to detect and correct corrosion damage to the airbrake levers and bearings caused by collection of water in the airbrake boxes, not detected during postflight checks. This condition could result in the airbrakes locking in the extended position and a consequent off-field or short landing.
