## Discrepancy

DURING INITIAL APPROACH FOR LANDING THE RIGHT HYDRAULIC SYSTEM LOST THE ENGINE DRIVEN PUMP AND ALL THE FLUID.  COM PROCEDURES WERE COMPLIED WITH AND THE EMERGENCY GEAR EXTENSION WAS ACCOMPLISHED.  THE AIRCRAFT LANDED WITHOUT FURTHER INCIDENT, STOPPED ON THE RUNWAY, AND WAS TOWED TO THE GATE.  MAINTENANCE FOUND THE LOWER HYDRAULIC ACCUMULATOR LEAKING AND REPLACED IT.  THE RIGHT SYSTEM PUMPS AND FILTERS WERE CHANGED, RESERVICED, AND LEAK CHECKED.  THE AIRCRAFT HAS RETURNED TO SERVICE.
