## Discrepancy

SEVERAL TIMES DURING THE FLIGHT, THE LT AND RT GEAR DOOR MAIN UNSAFE AND GEAR HANDLE LIGHTS ILLUMINATED. A LOUD THUMP WAS HEARD FROM THE MAIN GEAR AREA, THEN THE LIGHTS WENT OUT. MAINTENANCE INSPECTED THE AIRCRAFT AND ADJUSTED THE LANDING GEAR UPLOCK PROXIMITY SENSOR. OPERATIONAL CHECKS WERE GOOD AND THE AIRCRAFT WAS RETURNED TO SERVICE.
