## Discrepancy

NR 2 ENGINE EPR INDICATION FAILED TO REACH TARGET ON TAKEOFF.  THE TAKEOFF WAS ABORTED AND THE AIRCRAFT RETURNED TO THE GATE.  MAINTENANCE REPLACED THE EPR TRANSMITTER, INDICATOR AND A CRACKED FITTING IN THE PT7 SYSTEM.  IN ADDITION, THE ENGINE WAS FIELD TRIMMED PER PWA'S JT8D MAINTENANCE MANUAL.
