## Discrepancy

DURING CLIMBOUT, LEFT MAIN GEAR UNSAFE LIGHT REMAINED ON AFTER GEAR RETRACTION.  CREW RECYCLED GEAR WITH SAME RESULTS. FLIGHT CONTINUED TO DESTINATION AND LANDED WITHOUT INCIDENT.  NOTE:  GEAR INDICAITONS WERE NORMAL WHEN GEAR WAS EXTENDED FOR LANDING.  MAINTENANCE CYCLED GEAR NUMEROUS TIMES ON GROUND.  DISCREPANCY COULD NOT BE DUPLICATED.  REPLACED DOWNLOCK AND UPLOCK SENSORS AS A PRECAUTION, OPERATIONAL CHECK NORMAL.
