## Discrepancy

THE RT MLG RED UNSAFE LIGHT ILLUMINATED STEADILY AT FIRST, AND THEN FLASHED ON AND OFF INTERMITTENTLY WHEN GEAR WAS EXTENDED ON APPROACH TO IAH.  THE AIRCRAFT LANDED WITHOUT INCIDENT.  THE TARGETS, SENSORS, AND WIRING WERE VISUALLY INSPECTED AND CHECKED GOOD.  TROUBLESHOOTING THE WIRING IAW MM 32-64-01 AND 32-64-02 FOUND THE D4656P WIRING CONNECTOR AT FAULT. THE D4656P CONNECTOR WAS REPLACED.  OPERATIONAL CHECKS WERE GOOD.
