## Discrepancy

FLEX PWR SET FOR 50 PERCENT, THROTTLES  ADVANCED SMOOTHLY WHEN AUTOFLT SELECTED TO THE APPROPRIATE REDUCED PWR CHEVRON INDICATED SETTINGS ON THEN 1 GUAGE.  THROTTLES CLAMPED NORMALLY PRIOR TO 80KTS.  AFTER 80 KTS THE NR 3 ENGINE BEGAN NOTICEABLY SURGING WITH NR3 N1, N2 AND EGT FLUCTUATING WITH THE NR 3 THROTTLE CLAMPED AND NOT  MOVING.  SOON THEREAFTER THE NR 2 AND NR 1 THROTTLES  BEGAN RETARDING TO COMPENSATE FOR THE N1 OVERSPEED ABOVE THE CHEVRON.  TAKEOFF ABORTED BETWEEN 100 TO 110KTS.  REPLACED NR 3 ENGINE FUEL PUMP PER M/M 73-12-01-2.  ALSO REPLACED MAIN ENGINE CONTROL PER MM 73-20-01-2, BOTH LEAK CHECK GOOD ON WET MOTOR AND IDLE ENGINE RUN, WILL REQUIRE POWER TEST.
