## Discrepancy

ON APPROACH TO MKE CREW SELECTED LANDING GEAR DOWN.  LEFT & RIGHT MAIN EXTENDED SLOWLY AND LOCKED.  NOSE GEAR REMAINED IN WELL.  PER CHECKLIST CREW PERFORMED EMERGENCY EXTENSION AND ALL THREE GEAR EXTENDED AND LOCKED.  LANDING WAS UNEVENTFUL.  TROUBLESHOOTING DETERMINED THE LANDING GEAR CONTROL SWITCH HAD FAILED.  REPLACED LANDING GEAR CONTROL SWITCH WITH NEW.  OPS CHECK GOOD.
