## Discrepancy

ON APPROACH INTO APA, AFTER EXTENDING THE LANDING GEAR THE CREW NOTED THAT A DOWN AND LOCKED RT MAIN GEAR WAS NOT ILLUMINATED.  ALL OTHER INDICATIONS WERE NORMAL AND FLY-BY TOWER REPORTED GEAR LOOKED DOWN.  CREW DECLARED AN EMERGENCY, FOLLOWED ABNORMAL CHECKLIST WHICH INCLUDES USING EMERGENCY BLOW DOWN BOTTLE.  AIRCRAFT THEN LANDED NORMAL, WITH NO PROBLEMS.  AIRCRAFT WAS TOWED TO FBO WHERE MAINTENANCE DISCOVERED A FAILED LIGHT BULB.  ALL REQUIRED GEAR SWINGS WERE PERFORMED AND THE EMERGENCY BLOWDOWN SYSTEM WAS RESET AND SERVICED; ALL WORK WAS PERFORMED IN ACCORDANCE WITH OEM PROCEDURES.
