## Discrepancy

THE NR 1 ENGINE SURGED AND ROLLED BACK TO APPROXIMATELY 1.6 EPR AND 85 PERCENT ON TAKEOFF AT ROTATION.  THE ENGINE WOULD NOT RESPOND TO THROTTLE MOVEMENTS.  THE AIRCRAFT WAS RETURNED TO EWR WHERE IT LANDED WITHOUT INCIDENT.  MAINTENANCE REMOVED AND REPLACED THE NR 1 ENGINE FUEL CONTROL UNIT, FUEL PUMP AND FUEL HEATER AND LEAK CHECKS WERE GOOD.  AN ENGINE POWER ASSURANCE RUN WAS PERFORMED IAW MM 71-09-226, PAGE 209 AND ENGINE OPERATION CHECKED GOOD.
