## Discrepancy

DURING CLIMB-OUT FROM KTOL, THE CREW NOTICED HYDRAULIC QUANTITY DECREASING.  THE CREW RETURNED TO KTOL AND LANDED WITHOUT INCIDENT.

MAINTENANCE PERFORMED OPERATIONAL AND LEAK CHECK.  OPERATIONAL CHECK WAS GOOD AND NO LEAKS DETECTED IAW MAINTENANCE MANUAL 27-24-2.  AIRCRAFT RETURNED TO SERVICE.
