## Discrepancy

THE RT MLG UNSAFE LIGHT REMAINED ILLUMINATED AFTER GEAR RETRACTION.  THE GEAR WAS CYCLED AND THE UNSAFE LIGHT EXTINGUISHED.  THE FLIGHT CONTINUED TO IAH WHERE IT LANDED WITHOUT FURTHER GEAR INDICATION PROBLEMS.  MAINTENANCE REPLACED THE RT MLG UPLOCK SWITCH, A SIMULATED TEST CHECKED GOOD.
