## Discrepancy

WHEN THE ACFT DEPARTED AND THE LANDING GEAR WAS RETRACTED AFTER TAKEOFF, THE LANDING GEAR TRANSITION LIGHT REMAINED ILLUMINATED.  FLIGHT CREW CYCLED THE LANDING GEAR SEVERAL TIMES WITH SUCCESSFUL EXTENSIONS AND RETRACTIONS ON EACH EVENT.  WITH EACH EVENT THE LIGHT DID STAY ILLUMINATED AND DID NOT EXTINGUISH, SO THE CREW ELECTED TO RETURN TO DEPARTURE FOR INVESTIGATION. THE NOSE GEAR UPLOCK POSITION SWITCH WAS FOUND JUST OUT OF ADJUSTMENT, THE SWITCH WAS ADJUSTED AS NECESSARY AND THE ACFT DEPARTED WITHOUT INCIDENT.
