What was found
ON DECENT WHEN GEAR WAS SELECTED DOWN ONLY THE NOSE AND LEFT GEAR DOWN LIGHTS ILLUMINATED, THE PRESS TO TEST WAS CHECKED AND THE BULB WAS NOT BURNT OUT SO ATC WAS ADVISED AND THE APPROACH WAS BROKEN OFF TO RUN THE APPROPRIATE CHECKLIST. EMERGENCY EXTENSION AS PRESCRIBED IN THE CHECKLIST WAS INEFFECTIVE IN ILLUMINATING THE RIGHT GEAR DOWN LIGHT SO CHIEF PILOT WAS CONTACTED TO ADVISE, THE DECISION WAS MADE TO DECLARE AN EMERGENCY AND LAND RUNWAY 17 AND HAVE ALPINE GROWN PERSONAL WAITING TO GET THE GEAR PINS IN ASAP. A SOFT LANDING WAS MADE WHILE PUMPING THE EMERGENCY GEAR HANDLE AS INSTRUCTED IN THE CHECKLIST. THANKFULLY THE GEAR NEVER COLLAPSED AND THE AIRCRAFT WAS BROUGHT TO A SAFE STOP. MX CLEANED DOWN LOCK SWITCH CONNECTOR AND ADJSUTED LOWN LOCK SWITH IAW BEECH KING AIR 200 MM 32-60-01. OPS CHECK GOOD.
