## Discrepancy

FLT 4862 - DURING DESCENT INTO ATL FROM TYS, A TORQUE FLUCTUATION WAS NOTICED ON THE RIGHT ENGINE.  THE CREW REDUCED THE TORQUE TO APPROXIMATELY FIFTY PERCENT AND THE RIGHT ENGINE CONTINUED TO FLUCTUATE BETWEEN 0 TO 102 PERCENT.  THE CREW THEN REDUCED THE TORQUE TO FLIGHT IDLE AND IT REMAINED CONSTANT.  THE TOWER DECLARED AN EMERGENCY AND ROLLED THE EMERGENCY VEHICLES AS A PRECAUTION.  THE AIRCRAFT LANDED SAFELY IN ATL.  MAINTENANCE REMOVED AND REPLACED THE RIGHT TORQUE PICK-UP PROBE.  OPERATIONAL CHECKS GOOD.  AIRCRAFT OK FOR SERVICE.  (M)
