## Discrepancy

DURING APPROACH, LANDING GEAR WAS SELECTED DOWN AND PILOTS OBSERVED THREE RED LIGHTS ON THE LANDING GEAR SELECTOR PANEL AND ILLUMINATION OF THE NR 2 HYDRAULIC ISOLATION VALVE CAUTION LIGHT.  HYDRAULIC QUANTITIES AND PRESSURES REMAINED STEADY.  PILOTS DECLARED AN EMERGENCY AND PERFORMED A GO-AROUND THEN PERFORMED AN ALTERNATE GEAR EXTENSION.  AIRCRAFT LANDED NORMALLY AND TAXIED TO THE GATE WITH EMERGENCY VEHICLES FOLLOWING.  PILOTS REPORTED LOSS OF NOSE WHEEL STEERING AND OUTBOARD SPOILERS.  MAINTENANCE FOUND FLUID LEVELS TO BE ADEQUATELY SERVICED.  THE NR 2 RESERVOIR VALVE CONNECTOR WAS CLEANED AND SYSTEM CHECKED IAW PIEDMONT WORK CARD.  OPS CHECKS WERE NORMAL.  NEW INFORMATION ADDED.
