GLIDER CONTROL SURFACE MOVEMENT CHECKS - GLASFLUGEL 201B LIBELLE, BUT GENERALLY APPLICABLE TO ALL TYPES
During a recent GFA Form 2 inspection of a Libelle 201B, the aileron actuating mechanisms were dismantled and on reassembly the right and left actuators were interchanged inadvertently. The CoA Inspector checked the that the ailerons moved when the control column moved and the Daily Inspector and pilot for the evaluation flight also checked that the ailerons moved when the control column moved but all failed to observe that the ailerons moved in the correct sense; in fact the action was reversed. As a result on take off this control surface reversal resulted in a pilot amplified wing drop which led to a serious ground loop and damage to the glider.
