## Discrepancy

AFTER TAKEOFF FROM DEN, THE FLIGHT CREW NOTICED A DROP IN THE HYDRAULIC SYSTEM QUANTITY.  THE FLIGHT CREW RETURNED TO DEN FOR AN UNEVENTFUL LANDING.  MAINTENANCE INSPECTED THE AIRCRAFT WHICH REVEALED A LEAK AROUND THE LEFT AILERON PACK.  MAINTENANCE REPLACED THE LEFT HAND AILERON POWER CYLINDER PER THE AIRCRAFT MAINTENANCE MANUAL AND RETURNED AIRCRAFT TO SERVICE.
