## Discrepancy

WHILE ON CLIMB OUT, THE FLIGHT CREW NOTICED A LOSS OF THE A SYS HYD QTY, THE CREW DECLARED AN EMER & THEY RETURNED BACK.  FLIGHT CREW EXECUTED THE APPROPRIATE CHECKLISTS & BURNED OFF ENOUGH FUEL TO MEET THE LANDING WEIGHT.  WHEN THEY LANDED THE A SYS HYD QTY WAS INDICATING 5 PERCENT, & THE EMER BRAKES WERE UTILIZED.  FOUND A FAILED A SYS HYD RESERVOIR, PN 9914454-3.  THE RESERVOIR WAS REPLACED WITH AN OVERHAULED UNIT, BLEED, LEAK & OPERATIONAL CHECKS PERFORMED, WITH NO DEFECTS NOTED.  A SATISFACTORY CONFIDENCE FLIGHT WAS ACCOMPLISHED & THE ACFT WAS RETURNED TO SERVICE.
