## Discrepancy

ON DESCENT CAPT NOTICED LOSS OF HYDRAULIC PRESSURE ON THE RT SYSTEM AND DECLARED AN EMERGENCY. THE CREW USED THE ALTERNATE GEAR EXTENSION. THE FLIGHT LANDED UNEVENTFULLY, BUT REQUIRED TO BE TOWED OFF THE RUNWAY AND TO THE GATE. MAINTENANCE FOUND A BROKEN WIRE AT CONNECTOR P1-811. INSTALLED NEW CONNECTOR PINS PER SWPM 20-31-15. CHECKS NORMAL. THE AIRCRAFT WAS GROUNDED.
