## Discrepancy

THE NR 1 GENERATOR FAILED WHILE EN ROUTE.  THE APU WAS STARTED AND THE FIRE WARNING BELL SOUNDED WITH THE RED APU FIRE HANDLE ILLUMINATED.  THE APU START SWITCH WAS PLACED TO OFF AND THE FIRE WARNING SYSTEM TESTED GOOD.  THE AIRCRAFT WAS DIVERTED TO CMH WHERE IT LANDED WITHOUT INCIDENT.  TROUBLESHOOTING BY MAINTENANCE FOUND THE APU TORCHING  ON START.  THE APU FUEL CONTROL AND COMBUSTOR WERE REPLACED.  THE APU TAILPIPE FIRELOOP HARNESS AND EGT WIRE HARNESS WERE FOUND BURNT. BOTH HARNESSES WERE REPLACED.  THE EGT THERMOCOUPLE WAS REPLACED AS A PRECAUTIONARY MEASURE, OPERATION OF THE APU CHECKED GOOD.  IN ADDITION, THE NR 1 GENERATOR WAS REPLACED.
