## Discrepancy

DURING DISASSEMBLY FOR REBUILD ALL AND RUDDER PEDALS WERE FOUND TO BE DAMAGED DUE TO THE RETURN SPRING(40494100) CUTTING THROUGH LOWER HINGE SHAFT, WALL.  ALL 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.
