## Discrepancy

THE A-HYDRAULIC SYSTEM QUANTITY WAS LOST WHILE ON APPROACH.  THE A-SYSTEM HYDRAULIC QUANTITY LOSS CHECKLIST WAS COMPLIED WITH AND THE AIRCRAFT LANDED WITHOUT INCIDENT.  MAINTENANCE FOUND THE NR 2 SLAT  ACTUATOR HYDRAULIC PRESSURE LINE CRACKED AT B-BUT.  THE LINE WAS REMOVED AND REPLACED.  THE A-HYDRAULIC SYSTEM WAS SERVICED TO FULL.  IN ADDITION, THE NR 1 ENGINE DRIVEN HYDRAULIC PUMP WAS REMOVED AND REPLACED FOR NO OUTPUT.  THE ENGINES WERE RUN AND LEAK AND OPERATIONAL CHECKS WERE GOOD.
