## Discrepancy

DURING TAKEOFF ROLL BELOW 60 KTS (TPE), THE NR 4 ENGINE HAD SLOW EPR RISE AND THE TAKEOFF WAS ABORTED.  AN EPR CHECK BY THE CREW ON THE TAXIWAY CHECKED OK AND A NORMAL TAKEOFF WAS THEN MADE.  THE ENGINE WAS INSPECTED.  ALL SENSE LINES AND ELECTRICAL CONNECTORS WERE CHECKED AND FOUND TO BE OK.
