## Discrepancy

ON TAKEOFF AT 5000 MSL, EXPERIENCED AN UNCOMMANDED TORQUE INCREASE WITH AN EEC FAILURE LIGHT ON THE LEFT ENGINE.  TORQUE VALUE WENT TO 130 PERCENT FOR APPROXIMATELY 5 SECONDS BEFORE WE COULD GET AIRCRAFT POWER LEVER RETRACTED AND THE EEC SWITCH OFF.  RETURNED TO SLC.  REPLACED LEFT HMU AND EEC.
