## Discrepancy

THE FLIGHT CREW REPORTED THAT AFTER TAKEOFF AND GEAR RETRACTION THAT THE RIGHT MAIN GEAR DOOR INDICATOR SHOWED UNSAFE. THE CREW JAM THE CHECKLIST AND OPTED TO CONTINUE THE FLIGHT WITH RESTRICTIONS.  THE FLIGHT COMPLETED THE FLIGHT AND LANDED WITHOUT INCIDENT. THE MAINTENANCE TEAM TROUBLESHOT AND DETERMINED A DEFECTIVE GEAR DOOR UNLATCH SWITCH. THE DEFECTIVE SWITCH WAS REMOVED AND A NEW SWITCH WAS INSTALLED AND RIGGED. (P/N 1EN1-8) FUNCTIONAL CHECKS WERE SATISFACTORY AND THE AIRCRAFT WAS RETURNED TO SERVICE.
