## Discrepancy

SEA - FLIGHT 9999 - WITH THE GEAR RETRACTED AND IN LEVEL FLIGHT, THE LT MAIN GEAR DOOR CYCLED. ALSO, THE LT MAIN GEAR INDICATED UNSAFE. MAINTENANCE INSPECTED THE AIRCRAFT AND FOUND THE LT GEAR DOOR CLOSED PROXIMITY GAP SENSOR TOO FAR.  MAINTENANCE RE-RIGGED THE PROX SENSORS AND PERFORMED OPERATIONAL CHECKS. THE CHECKS WERE GOOD AND THE AIRCRAFT WAS RETURNED TO SERVICE.
