## Discrepancy

DURING TAKEOFF ROLL, TWO ENGINE COMPRESSOR STALLS WERE HEARD BY THE FLIGHT CREW.  IT WAS NOT DETERMINED WHICH ENGINE OR BOTH EXPERIENCED THE COMPRESSOR STALLS.  THE TAKEOFF WAS ABORTED AT 120 KNOTS WITHOUT INCIDENT.  MAINTENANCE REPLACED THE FUEL CONTROL UNITS LOCATED ON THE LEFT AND RIGHT ENGINES.  OPERATIONAL CHECK NORMAL.
