## Discrepancy

ON TAKEOFF FROM CMH THE CREW RECEIVED A LANDING GEAR DISAGREE MSG.  THE FLIGHT RETURNED TO THE FIELD AND MADE A NORMAL LANDING.  UPON INSPECTION BY MAINTENANCE AND AFTER SEVERAL GEAR SWINGS, WAS ABLE TO DUPLICATE THE FAULT.  MAINTENANCE REPORTED THAT THE LT MLG UPLOCK BOX WAS AT FAULT.  THE UPLOCK BOX WAS REPLACED AND A TEST FLIGHT FOLLOWED.  THE TEST FLIGHT PROVED SATISFACTORY AND THE AIRCRAFT WAS RETURNED TO SERVICE.
