## Discrepancy

THE APU FIRE LIGHT ILLUMINATED ON SHORT FINAL INTO CLE DURING APU START.  THE AIRCRAFT LANDED AT CLE WITHOUT INCIDENT. MAINTENANCE FOUND THAT THE APU HAD TORCHED ON START RESULTING IN BURN THROUGH OF HARNESS FOR TAILPIPE FIRE DETECTOR.  THE APU COMBUSTOR AND THE FIRE DETECTOR HARNESS WERE REMOVED AND REPLACED.  THE APU STARTED AND RAN NORMALLY.  ALSO,THE FIRE DETECTION SYSTEM TESTED NORMALLY.
