## Discrepancy

DURING CRUISE THE RIGHT HYDRAULIC SYSTEM QUANTITY DECREASED TO ZERO AND SYSTEM PRESSURE LIGHT ILLUMINATED.  FLIGHT CONTINUED TO MSP AND LANDED WITHOUT INCIDENT.  MAINTENANCE FOUND A HYDRAULIC PRESSURE LINE AND THE ENGINE DRIVEN PUMP LEAKING.  REMOVED AND REPLACED HYDRAULIC PRESSURE LINE, ENGINE DRIVEN PUMP, AND FILTERS.  THE HYDRAULIC SYSTEM WAS FLUSHED, SERVICED, TESTED AND RETURNED TO SERVICE.
