## Discrepancy

DURING ANNUAL INSPECTION, PILOT SIDE CONTROL HAD EXCESS LOOSE MOTION.  THE U-JOINT THAT CONNECTS THE CONTROL WHEEL SHAFT TO THE YOKE WAS WORN ENOUGH, THAT IT WAS SOON TO BE HAZARDOUS TO FLIGHT SAFETY.  SUMITTER STATED THIS IS THE FOURTH ONE SEEN IN THIS SHAPE.  THIS NEEDS TO BE CHECKED AT EACH INSPECTION.
