## Discrepancy

THE RT MLG RED UNSAFE LIGHT REMAINED ILLUMINATED WHEN LANDING GEAR WAS EXTENDED ON APPROACH.  THE GEAR WAS CYCLED AND THE RED LIGHT EXTINGUISHED.  THE AIRCRAFT LANDED WITHOUT INCIDENT.  MAINTENANCE REMOVED AND REPLACED THE LANDING GEAR ACCESSORY UNIT AND OPERATIONAL CHECKS WERE GOOD.
