## Discrepancy

IAH - FLIGHT 2308, THE CREW REPORTED A LOSS OF N1, ITT DATA, A DAU FAIL MESSAGE, AND A FUEL IMBALANCE ON CLIMB.  THE AIRCRAFT RETURNED TO IAH WHERE IT LANDED WITHOUT INCIDENT.  MAINTENANCE REMOVED AND REPLACED THE NUMBER ON DAU, OPERATIONALLY TESTED WITH NO DEFECTS, AND THE AIRCRAFT WAS APPROVED FOR RETURN TO SERVICE.
