## Discrepancy

DURING INSPECTION FOR HYDRAULIC SEEP AT BOTTOM OF RUDDER, FOUND ELEVATOR SERVO PRESSURE LINE CHAFFED THROUGH RUDDER PUSH-PULL TUBE.  SUSPECTED LINE WAS TIGHTENED WITH A PRELOAD THAT TWISTED THE LINE TO CHAFE ON THE RUDDER PUSH-PULL TUBE.  THE LINE WAS LOOSENED AND REPOSITIONED ITSELF SO AS TO EXTEND AND RETRACT WITH CONTROL MOVEMENT WITHOUT INTERFERENCE WITH THE RUDDER PUSH-PULL TUBE.  PUSH-PULL TUBE HAD A HOLE CHAFED THROUGH AND REQUIRED REPLACEMENT.  THIS AREA IS ONLY INSPECTED DURING A 3B (3600 HOURS) OR C (6 YEARS) IAW THE MFG MM, CHAPTER 5-10-00.
