## Discrepancy

CAPTAIN REPORTED THAT RT RED MAIN LANDING GEAR LIGHT TURNED ON. THE PROXIMITY SWITCH UNIT WAS TESTED, LIGHT PANEL WAS CHECKED AND SENSORS WERE VERIFIED BUT FAILURE CONTINUED. THE PROXIMITY SWITCH UNIT WAS REPLACED AND FAILURE CODE 310 WAS SHOWN AND RED LIGHTS TURNED ON. THE PROXIMITY SWITCH CARD WAS REPLACED IAW MM 32-60-00, TESTED CORRECT.
