## Discrepancy

FUEL LEAKING FROM TCC VALVE ACTUATOR ON LT ENGINE.  CONFIRMED FUEL LEAKAGE OUT OF PRESSURE WEEP HOLE.  REPLACED ACTUATOR WITH A PART THAT WAS TAGGED SERVICEABLE BUT LOOKED OLD AND DIRTY.  NEW VALVE IS LEAKING OUT OF SAME WEEP HOLE AT RATE OF 2 DPM.  NEEDS NEW VALVE.  REPLACED TCC ACTUATOR ON ENG NR1.  RAN ENGINE AND LEAK CHECKED NO LEAKS WERE NOTED.
