## Discrepancy

PIT - FLT 864, AFTER TAKEOFF FROM TPA, ENROUTE TO PIT, THE RT MLG RED LIGHT REMAINED ON WITH GEAR HANDLE IN THE UP POSITION.  LANDING GEAR APPEARED TO BE LOCKED UP.  AFTER APPROXIMATELY 20 MINUTES, THE RED LIGHT EXTINGUISHED.  FLIGHT CONTINUED ON TO PIT AND LANDED WITHOUT FURTHER INCIDENT.  LANDING GEAR OPERATED NORMALLY DURING APPROACH AND LANDING.  MX REMOVED AND REPLACED THE RT MLG UPLOCK ACTUATOR PER MM 32-32-41-404-006.  RETRACTION/EXTENSION CHECKS GOOD PER MM32-3200/501.  LEAK CHECK AND INDICATIONS GOOD.
