## Discrepancy

MSO - FLIGHT 2382 - THE MAIN LANDING GEAR DOORS OPENED BRIEFLY DURING FLIGHT.  THE LEFT DOOR AND RIGHT DOOR AMBER LIGHTS ILLUMINATED WITH ASSOCIATED AIR NOISE.  THE DOORS WERE OPEN FOR 2 SECONDS.  MAINTENANCE INSPECTED THE AIRCRAFT AND INTERROGATED THE PSEU.  MAINTENANCE FOUND THE RIGGING NEAR GAP TOO FAR.  THE PROXIMITY SENSOR WAS RE-RIGGED AND THE OPERATIONAL CHECKS WERE GOOD.  THE AIRCRAFT WAS RETURNED TO SERVICE.
