## Discrepancy

THE RT MLG RED LIGHT REMAINED ILLUMINATED WITH NO GREEN LIGHT WHEN GEAR WAS EXTENDED ON APPROACH TO IAH.  A MANUAL GEAR EXTENSION WAS PERFORMED SUCCESSFULLY AND THE AIRCRAFT LANDED WITHOUT INCIDENT.  MAINTENANCE FOUND THE RT MLG UPLOCK ACTUATOR AT FAULT.  THE UPLOCK ACTUATOR WAS REPLACED IAW MM 32-32-41.  LEAK AND OPERATIONAL CHECKS WERE GOOD.
