## Discrepancy

DURING APPROACH AT 7,000 FEET, CREW NOTED A BURNING SMELL IN COCKPIT FOLLOWED FIVE MINUTES LATER BY A VENT EXTRACT FAULT.  FOLLOWED COCKPIT OPERATING MANUAL PROCEDURES, DECLARED AN EMERGENCY AND LANDED WITHOUT INCIDENT.  MAINTENANCE FOUND THE AVIONICS COOLING EXTRACT FAN SEIZED.  REPLACED SAME, OPERATIONAL CHECK OK.
