## Discrepancy

LEFT & RT HYD PRESS WARNING LIGHTS ILLUMINATED IN FLIGHT.  LOSS OF HYD PRESS WAS CONFIRMED BY A ZERO PSI INDICATION ON THE HYD PRESS INDICATOR.  THE CAPTAIN DECLARED AN EMERGENCY, PERFORMED AN EMERGENCY LANDING GEAR EXTENSION & MADE A SAFE LANDING. UPON INSPECTION, IT WAS DISCOVERED THAT A LG UP HYD LINE IN THE RT WW HAD FAILED & SUBSEQUENTLY ALLOWED ALL OF THE HYD FLUID TO JETTISON THE ACFT.  THE LINE WAS REPLACED WITH A SERVICEABLE PART, THE HYD FILTER WAS INSPECTED FOR DEBRIS WITH NONE FOUND, OPERATIONAL & LEAK CHECK WERE PERFORMED & THE ACFT WAS RETURNED TO SERVICE.
