## Discrepancy

DURING DESCENT, EICAS MESSAGES "MAU 1B FAIL" AND "SPOILER FAIL" APPEARED.  ALSO LOST PITCH TRIM INDICATION AND GPS 1.  RAN QRH, DECLARED AN EMERGENCY AND DIVERTED TO IND.  LANDED WITHOUT INCIDENT.  MAINTENANCE RESET THE MAU AND WAS UNABLE TO DUPLICATE FAULT AT THAT TIME.  RECOMMENDATION FROM EMBRAER WAS TO MONITOR.
