## Discrepancy

DCA - FLT 6529 - EN ROUTE BOS-DCA - A VIBRATING NOISE WAS HEARD FROM UNDER THE COCKPIT.  AN ELECTRICAL ODOR WAS THEN NOTICED, FOLLOWED BY A VENT "BLOWER FAULT".  THE VENTILATION BLOWER WAS PUT INTO OVER-RIDE, AND THE ELECTRICAL ODOR WENT AWAY.  FLIGHT LANDED IN DCA WITHOUT INCIDENT.  MAINTENANCE REPLACED THE AVIONICS FAN.  OPERATIONALLY CHECKS OK.  (M)
