## Discrepancy

DURING TAXI TO POSITION FOR TAKEOFF, THE RIGHT RUDDER RETURN SPRING FAILED AT THE ATTACHMENT HOOK TO THE CABLE BELLCRACK.  THE PILOT HEARD A NOISE BUT DID NOT REALIZE THE SPRING HAD FAILED UNTIL LATE IN THE ROLLOUT.  THE FLIGHT CYCLE WAS COMPLETED WITHOUT EVENT.  ABOVE NORMAL RIGHT RUDDER PRESSURE WAS REQUIRED TO CORRECT YAW.  PART FAILURE APPEARS TO BE THE RESULT OF FATIGUE.
