## Discrepancy

THE CREW REPORTED APU FAIL ON GROUND AND AUTO SHUTDOWN IN FLIGHT WITH A FUEL ODOR PRESENT.  THE AIRCRAFT LANDED WITHOUT INCIDENT WHERE MAINTENANCE PLACED THE APU ON MEL 49-00-00 CONTROL NR 045133, AND THE AIRCRAFT WAS APPROVED FOR RETURN TO SERVICE.  ON 08/21/04 THE AIRCRAFT RETURNED WHERE MAINTENANCE REMOVED AND REPLACED THE APU HIGH OIL TEMP SWITCH, AND REMOVED THE APU FROM MEL. THE AIRCRAFT WAS THEN APPROVED FOR RETURN TO SERVICE.
