## Discrepancy

ON APPROACH INTO MKE THE CREW REPORTED AN E1 FIRE DETECT FAIL MESSAGE.  THE QRH WAS FOLLOWED, E1 WAS STILL RUNNING WITH ALL PARAMETERS AT NORMAL LEVELS AND THE AIRCRAFT LANDED WITHOUT INCIDENT.  THE CREW DID NOT DECLARE AN EMERGENCY.  THE AIRCRAFT WAS INSPECTED BY FIRE CREWS ON THE GROUND AND NO INDICATIONS OF FIRE WITH NONE FOUND.  THE CREW SHUT DOWN E1 AND TAXIED TO THE GATE WITHOUT INCIDENT.  MAINTENANCE TROUBLESHOT THE FAULT TO A SHORTED WIRE W407-0012-20 IN THE W407 HARNESS.  THE HARNESS WAS REPLACED WITH NO FURTHER DEFECTS NOTED.
