## Discrepancy

THE RT MLG GREEN LIGHT DID NOT ILLUMINATE WHEN GEAR WAS EXTENDED FOR LANDING ON APPROACH.  A MANUAL GEAR EXTENSION WAS PERFORMED, BUT THE LIGHT DID NOT COME ON. A TOWER FLY-BY WAS CONDUCTED AND THE GEAR WAS CONFIRMED DOWN AND LOCKED.  THE AIRCRAFT LANDED WITHOUT INCIDENT.  MAINTENANCE FOUND PIN 5 AT PLUG ON RT MLG DOWNLOCK SWITCH BROKEN.  THE PLUG AND SWITCH WERE REPLACED AND OPERATIONAL CHECK WAS GOOD.
