## Discrepancy

BEFORE LANDING, WHEN GEAR WAS SELECTED DOWN, THE RT GREEN DOWN LIGHT FAILED TO ILLUMINATE.  THE GEAR UNSAFE LIGHT AND HORN DID NOT INDICATE AN UNLOCKED GEAR.  AFTER A FLYBY AND A VISUAL LOOK BY GROUND PERSONNEL, THE FAILED GEAR LIGHT CAME ON AND A LANDING WAS MADE WITH NORMAL INDICATORS.  THE DOWN LOCK SWITCH WAS TESTED AND FOUND INTERMITTENT.  THE SWITCH WAS REPLACED WITH A NEW PART AND FUNCTION TESTED FOR PROPER CONSISTENT FUNCTION.  (K)
