## Discrepancy

AT FL430 WE RECEIVED HYD PRESS LOW R CAS MESSAGE. ON HYDRAULIC SYSTEMS PAGE WE COULD SEE THE VOLUME OF FLUID SLOWLY DECREASING. EVENTUALLY CAS MESSAGE HYD VOLUME LOW ILLUMINATED. FOLLOWED QRH & UNLOADED BOTH HYDRAULIC PUMPS. PULLED BLOWDOWN BOTTLE FOR GEAR & LANDED WITH EMERGENCY BRAKES. UPON WALK AROUND NOTICED RT ENGINE WAS STILL LEAKING HYD FLUID FROM THE DRAIN MAST.  FOUND THE RH HYDRAULIC PUMP TO BE LEAKING STATICALLY. INSTALLED A REPAIRED UNIT IAW AMM TASK 29-10-05. SERVICED THE HYDRAULIC RESERVOIR IAW AMM TASK 12-10-30. PERFORMED OPS AND LEAK CHECK OF THE SYSTEM WITH NO DEFECTS NOTED.
