## Discrepancy

PHX - AIR TURNBACK - 1/31/01 - AFTER DEPARTURE FROM PHX THE AIRCRAFT LOST A-SYSTEM HYDRAULIC QUANTITY AND THE AIRCRAFT RETURNED TO PHX AND MADE AN UNEVENTFUL LANDING.  MAINTENANCE FOUND A UNION ON THE NR 5 INBOARD GROUND SPOILER ACTUATOR LEAKING, CRACKED.  THE UNION AND O-RING WERE REPLACED.  THE NR 1 ENGINE DRIVEN HYDRAULIC PUMP SHOWED SIGNS OF LEAKAGE AND WAS CHANGED AS WELL BUT THE CAUSE OF THE QUANTITY LOSS WAS THE SPOILER ACTUATOR UNION.
