Inspection to Rudder Control Linkage Required Within 200 Hours for Diamond Twin Operators

Diamond has issued a revised Airworthiness Directive for the DA42, DA42 NG, and DA42 M-NG aircraft that replaces a rudder axle, superseding a previous publication regarding the same part. The Directive orders the inspection of a self-locking nut used in the rudder T-yoke's bolt, and its installation should the nut be missing to begin with. Should the assembly not be correctly installed, operators run the risk of developing increasing play in the vertical movement of the bolt, diminishing effective rudder control in flight.
