## Discrepancy

DURING DISASSEMBLY FOR REBUILD ALL 4 RUDDER PEDALS WERE FOUND TO BE DAMAGED DUE TO THE RETURN SPRING (40941-00) CUTTING THROUGH LOWER HINGE SHAFT WALL.  ALL 4 HAD BEEN WELD REPAIRED BUT WERE AGAIN WORN THROUGH.  ALL REPLACED NEW AND APPEAR TO HAVE SAME WALL THICKNESS.  AS THE WEAR PROGRESSES THE POTENTIAL FOR BINDING EXISTS.
