## Discrepancy

(CAN) DURING C CHECK INSPECTION, ELEVATOR PUSH/PULL CONTROL ROD WAS FOUND WITH A WEAR MARK OF 1.37 LONG, .34  WIDE AND .0125 DEEP.  THE WEAR MARK WAS CAUSED BY INTERFERENCE WITH A GEAR TYPE CLAMP ON AN ECS DUCT UNDER THE AFT CABIN VANITY.  THE GEAR/SCREW PORTION OF THE CLAMP WAS POSITIONED AGAINST THE TUBE.  LOOSENING THE CLAMP AND ROTATING IT SO SCREW/GEAR PORTION WAS AT 12 O`CLOCK POSITION RECTIFIED THE INTERFERENCE PROBLEM. CONTROL ROD WAS REPLACED WITH NEW UNIT.
