## Discrepancy

THE CREW REPORTED THE NR 1 HYDRAULIC QUANTITY WAS LOW DURING FLIGHT.  AFTER LANDING THE CREW RECEIVED A NR 1 HYDRAULIC FAIL MESSAGE.  MAINTENANCE INSPECTED AND FOUND THE GROUND SPOILER ACTUATOR CRACKED AND LEAKING.  MAINTENANCE REPLACED THE GROUND SPOILER ACTUATOR.  OPS CHECKED GOOD.
