THE CREW EXPERIENCED AN UNCOMMANDED YAW TO THE RIGHT WHILE IN CRUISE FLIGHT AT FL410 WITH THE AUTO PILOT ENGAGED. A NORMAL LANDING WAS MADE WITHOUT INCIDENT AT THE INTENDED DESTINATION. EXAMINATION OF THE AIRPLANE'S RUDDER CONTROL REVEALED THAT THE SHAFT PORTION OF THE RUDDER QUADRANT WAS FRACTURED. METALLURGICAL EVALUATION OF THE FRACTURED SURFACE REVEALED THAT THE SEPARATION OF THE SHAFT PORTION WAS THE RESULT OF STRESS CORROSION CRACKING THAT INITIATED FROM OPPOSITE SIDES OF THE SHAFT AND PROGRESSED INWARD UNTIL ABOUT 60% OF THE SHAFT CROSS SECTION CRACKED DUE TO POOR CHOICE OF MATERIAL, IMPROPER RADIUS, AND EXCESSIVE TORQUE ON THE SHAFT NUT.
