## Discrepancy

DURING OPERATIONAL CHECK FLIGHT OF AIRCRAFT, PILOT ADVANCED POWER LEVERS FORWARD AND NOTED LT ENG (N) REACHED MAX OF 117 PERCENT N2, REACHED MAXIMUM OF 100 PERCENT.  IT IS DETERMINED THAT PROBABLE CAUSE OF OVERSPEED WAS ACHIEVED BY WORN THROTTLE LEVER LINK NOT PROVIDING ACCURATE RANGE OF MOTION TO CORRECTLY ACTUATE THROTTLE STOP.  ENGINE LEVERS WERE ENABLE TO ADVANCE FURTHER THAN NORMAL, CAUSING OVERSPEED CONDITION.  IT IS RECOMMENDED THAT LINK AND ASSOCIATED HARDWARE BE REPLACED.  (K)
