## Discrepancy

DURING TAKEOFF ROLL AT 80 KNOTS, THE RIGHT ENGINE EPR INDICATION BEGAN DECREASING.  CREW ABORTED TAKEOFF AND RETURNED TO THE GATE.  MAINTENANCE REPLACED THE RIGHT ENGINE P AND D VALVE, FUEL CONTROL, AND INSPECTED THE ENGINE INLET AND EXHAUST.  LEAK AND OPERATIONAL CHECK OK.  FINAL ANALYSIS REVEALS P AND D VALVE TO BE ROOT CAUSE.
