## Discrepancy

THE RT HYDRAULIC SYSTEM PRESSURE AND QUANTITY DROPPED TO ZERO IN-FLIGHT.  THE LOSS OF PRESSURE AND FLUID WAS ACCOMPANIED BY ILLUMINATION OF THE RT HYD PRESS LOW AND RUDDER CONTROL MANUAL ANNUNCIATOR LIGHTS.  THE AIRCRAFT LANDED WITHOUT INCIDENT.  MAINTENANCE FOUND A BROKEN HYDRAULIC PRESSURE LINE IN THE RT WHEELWELL.  A FLEX LINE WAS INSTALLED AND A DIP WAS ISSUED TO REPLACE THE FLEX LINE WITHIN 1200 HOURS OR 500 FLIGHTS.  THE HYDRAULIC SYSTEM WAS SERVICED AND LEAK CHECK WAS GOOD.
