## Discrepancy

ON TAKEOFF, THE NR 3 ENGINE EPR INDICATION WAS UNSTABLE AND EXCEEDED THE TARGET VALUE OF THE DAY.  THE TAKEOFF WAS ABORTED AND THE AIRCRAFT RETURNED TO GATE.  THE NR 3 EPR SYSTEM WAS PLACED ON MEL AND THE AIRCRAFT CONTINUED IN SERVICE.  MAINTENANCE SUBSEQUENTLY REPLACED THE EPR TRANSMITTER.  THE ENGINE WAS RUNUP AND CHECK OK.  AIRCRAFT RETURNED TO SERVICE.
