## Discrepancy

(CAN) DURING CRUISE ECAM INDICATION OF LOW PRESSURE ON THE #2 HYDRAULIC PUMP FROM THE GREEN SYSTEM. PUMP SELECTED OFF. SHORTLY AFTER CREW NOTICED THE GREEN SYSTEM QUANTITY DECREASING AND SUBSEQUENT ECAM WARNING. AFTER LANDING, INVESTIGATION REVEALED THAT THE #1 AND #2 PUMPS HAD FAILED. THE #2 RETURN FILTER AND H.P. FILTER WERE OKAY EXCEPT THE CASE DRAIN HAD A FEW PARTICLES OF BRASS. THE #1 PUMP HAD CRACKED AT THE AFT PLATE FACE CAUSING FLUID LOSS AND THE #2 PUMP FAILURE. BOTH PUMPS SENT TO AIR FRANCE FOR INVESTIGATION.
