## Discrepancy

ENGINE THROTTLE LEVER JAMMED UP AND WOULD NOT COME OUT OF REVERSE.  MAINTENANCE INSPECTED, CHECKED RIGGING, LUBRICATED, PERFORMED A PERFORMANCE RUN, BUT COULD NOT DUPLICATE THE PROBLEM.  2 FLIGHT LEGS LATER THE ENGINE WOULD NOT GO INTO FORWARD THRUST.  MAINTENANCE AGAIN LOOKED AT THE ENGINE AND DURING THE ENGINE RUN, THE THROTTLE LEVER, AFTER BEING RUN UP TO POWER, WOULD NOT RETARD BACK TO THE FLIGHT IDLE GATE.  THE INSPECTION FOUND OUT-OF-ROUND WEAR ON THE 2520569 BUSHING ATTACHED TO THE 3240570 LINKAGE CAUSING THE BUSHING TO HANG UP.  LINKAGE ALSO SHOWED WEAR BETWEEN BUSHING AND THREADED END OF LINKAGE.  REPLACEMENT OF BUSHING AND LINKAGE RESOLVED THE ISSUE.
