## Discrepancy

DURING DESCENT, PILOT REPORTED NR 2 ENG N1, N2, EGT AND FUEL FLOW WERE FLUCTUATING DRASTICALLY, HIGH POWER TO LOW PWR WITH NO APPARENT YAW OF THE PLANE.  PILOT STATES THAT IT SEEMED LIKE THE NR 2 ENG WAS OPERATING NORMALLY, BUT IGNITION DID TURN ON AUTOMATICALLY WHEN SITUATION OCCURRED AND THEY NOTICED AUTO THRUST OF THE NR 2 ENG LAGGED SLIGHTLY BEHIND THE NR 1 ENG.  MX PERFORMED TROUBLESHOOTING AND INSP IAW TSM 70-00-00-810-866 AND TSM 73-20-00-810-920. MX REMOVED AND REPLACED THE NR 2 ENGINE T-12 SENSOR IAW AMM 73-21-40 PB401.  ACFT WAS DETERMINED OK FOR CONTINUED SERVICE.
