## Discrepancy

ON TAKEOFF (NON-PROFILE, AUTOTHROTTLES OFF PER MEL)  THROTTLES SPLIT ONE KNOB LENGTH AFTER GEAR RETRACTION. TAKE OFF POWER WAS SET AT 101.5 N1 ON BOTH ENGINES.   HOWEVER, SOMETIME AFTER ROTATION, THE NUMBER 2 ENGINE INCREASED TO 108.5 N1 DESPITE AUTOTHROTTLES AND   ATS LEVER DEACTIVATED. THIS RESULTED IN RIGHT THROTTLE BEING ONE KNOB SPLIT FORWARD OF LEFT THROTTLE LEVER.   CORRECTED MISMATCH AFTER GEAR RETRACTION AND CONTINUED FLIGHT WITHOUT FURTHER INCIDENT. C/W FADEC GROUND TEST PER M.M. 73-21-30 NO FAULTS NOTED REPLACED THRUST   CONTROL COMPUTER IAW A300-600 AMM 22-36-34-04-01. REPLACED FAC/ATS PANEL IAW AMM  22-25-12-4.
