## Discrepancy

MDW - ON FLAP EXTENSION, DID NOT GET A BLUE LIGHT AT FIVE DEGREES FLAP.  THE LEADING EDGE FLAP PANEL INDICATED THE NR 4 FLAP DID NOT EXTEND.  VISUAL INSPECTION IN FLIGHT INDICATED THE FLAP TO BE DOWN.  AIRCRAFT DIVERTED TO ORD DUE TO A LONGER RUNWAY AND AIRCRAFT LANDED WITHOUT INCIDENT.  REPLACED THE NR 4 LEADING EDGE FLAP POSITION SWITCH AND OPERATIONAL CHECK NORMAL.
