## Discrepancy

SHIP 9533 - THE FLIGHT CREW DECLARED AN EMERGENCY DUE TO THE "RT GEAR UNSAFE" INDICATION ILLUMINATING SHORTLY AFTER TAKEOFF. ON APPROACH, THE GEAR WAS SELECTED DOWN AND THREE GREEN "DOWN & LOCKED" INDICATIONS ILLUMINATED. CORRECTIVE ACTION: THE AIRCRAFT WAS FERRIED TO ATL WHERE MAINTENANCE FOUND ONE OF THE RT MLG UP-LOCK SPRINGS MISSING. THE SPRING WAS REPLACED, THE PROX SENSOR WAS ADJUSTED, AND GEAR SWINGS WERE PERFORMED WITHOUT ANY FURTHER FAULTS. (LP #8421858)
