## Discrepancy

ON TAKEOFF ROLL, THE NR 1 HYDRAULIC SYSTEM QUANTITY INDICATOR DROPPED TO 2 GALLONS.  FLIGHT CREW FOLLOWED COM PROCEDURE AND RETURNED TO MSP.  FLIGHT LANDED WITHOUT INCIDENT.  ON TAXI IN, THE NR 1 QUANTITY WENT TO 6 GALLONS.  MAINTENANCE SERVICED AND LEAK CHECKED THE NR 1 SYSTEM.  NO LEAKS WERE FOUND.  FOUND NR 1 HYDRAULIC QUANTITY INDICATOR STICKING.  REPLACED NR 1 QUANTITY INDICATOR.  OPERATIONAL CHECK GOOD.
