## Discrepancy

AIRCRAFT START SEQUENCE PER CHECKLIST WAS NORMAL AS WELL AS TAXI TO RUNWAY. UPON RECEIVING TAKEOFF CLEARANCE, AIRCRAFT WAS POSITIONED ON RUNWAY 20R AND THROTTLES WERE SLOWLY ADVANCED. THE RIGHT THROTTLE WOULD NOT ADVANCE PAST APPROXIMATELY 25%. AIRCRAFT WAS SLOWED AND A REQUEST FOR CANCELLATION OF TAKEOFF WAS MADE WITH KSNA TOWER. AIRCRAFT WAS TAXIED BACK TO ACI NORTH TO AWAIT FURTHER INSTRUCTIONS FROM MAINTENANCE. RIGHT THRUST REVERSER SYSTEM WAS INSPECTED AND FOUND THE RIGHT THRUST REVERSER FEEDBACK CABLE CLEVIS ATTACHMENT AT REVERSER WAS BENT AND SEPARATED AT THREADED AREA. FURTHER INSPECTION REVEALED THE FEEDBACK CABLE CLEVIS BEARING WAS SEIZED WHICH CAUSED THE FAILURE DURING THE PREVIOUS THRUST REVERSER USAGE.
