## Discrepancy

GEG - FLIGHT 2323 - CRUISING AT 25,000 FT, THE LEFT AND RIGHT MAIN GEAR DOORS WERE CYCLING.  THE LEFT AND RIGHT YELLOW GEARS FLASHED ONE TIME.  ONLY THE LEFT RED LIGHT ILLUMINATED.  MAINTENANCE INSPECTED THE AIRCRAFT AND REPLACED THE RIGHT UPLOCK PROXIMITY SENSOR.  OPERATIONAL CHECKS WERE PERFORMED AND CHECKED GOOD.  THE AIRCRAFT WAS RETURNED TO SERVICE.
