## Discrepancy

THE NR 2 HYDRAULIC SYSTEM WAS OBSERVED TO BE AT ONE GALLON DURING DESCENT.  THE EMERGENCY CHECKLIST WAS ACCOMPLISHED AND THE AIRCRAFT LANDED WITHOUT INCIDENT.  MAINTENANCE FOUND THE NR 2 HYDRAULIC SYSTEM BALANCE VALVE LEAKING.  THE BALANCE VALVE WAS REMOVED AND REPLACED, THE NR 2 HYDRAULIC SYSTEM WAS SERVICED, LEAK AND OPERATIONAL CHECKS WERE GOOD.
