## Discrepancy

ON THE TAKEOFF ROLL, LT ENGINE TORQUE INDICATION WAS NOT AT THE MINIMUM LEVEL FOR TAKEOFF.  CREW ABORTED THE TAKEOFF AND RETURNED TO THE TAXIWAY.  CONDUCTED A POWER ASSURANCE RUN TO CHECK ENGINE PARAMETERS.  ALL CHECKED NORMAL, CREW CONTINUED WITH TAKEOFF.  PROBLEM OCCURRED IN-FLIGHT, CREW CONTINUED WITH THE FLIGHT AND LANDED AT THE ORIGINAL DESTINATION WITHOUT FURTHER INCIDENT.  CAK MX REPLACED LT ENGINE TORQUE SENSOR I.A.W. M.M. 77-11-00.
