## Discrepancy

LOSS OF GREEN HYD SYSTEM ACCOMPLISH CHECK OF GREEN ENGINE DRIVEN PUMP FOR A POSSIBLE CAVITATION CONDITION.  SEE TSM TASK 29-11-00-810-803-A FOR FURTHER TROUBLESHOOTING INFO.  ACP CHECK OF EDP AND ALL SYSTEM DP'S ON FILTERS ALL GOOD.  CREW COMMENTED WHEN THEY SAW THEY WERE LOSING FLUID, SHUT OFF PUMP.  FOUND GREEN RES WITH 25 PERCENT QTY OK.  PUMP NEVER CAVITATED.  REMOVED HYD PRESSURE LINE.  NO FLUID IN GREEN HYD SYSTEM.  10 MINUTES INTO CRUISE, ECAM DISPLAYED AND ZERO FLUID IN GREEN SYSTEM.  REPLACED HYD PRESSURE FEED LINE IN NR 1 PYLON, SVC HYD QTY'S.
