## Discrepancy

DURING DESCENT, AN ELECTRICAL BURNING ODOR WAS NOTICED IN THE COCKPIT FOLLOWED BY VENT BLOWER FAULT MESSAGE.  COMPLIED WITH COM PROCEDURES, DECLARED AN EMERGENCY, AND LANDED WITHOUT INCIDENT.  MAINTENANCE REPLACED THE AVIONICS VENTILATION INLET BLOWER FAN AND SYSTEM FILTER.  OPERATIONAL CHECK OK.
