## Discrepancy

DURING TAKEOFF ROLL AT 80 KNOTS, THE RIGHT ENGINE N1 AND EPR INDICATIONS ROSE ABOVE PRESET LIMITS.  TAKEOFF WAS ABORTED AND DURING TAXI, THE RIGHT ENGINE WOULD NOT RESPOND TO THROTTLE MOVEMENTS.  THE RIGHT ENGINE WAS SHUT DOWN AND AIRCRAFT RETURNED TO THE GATE.  MAINTENANCE REPLACED THE RIGHT ENGINE N1 TACH GENERATOR AND FUEL CONTROL UNIT.  LEAK AND OPERATIONAL CHECK OK.
