## Discrepancy

DURING A RETURN FLIGHT,  CREW DETECTED AN ELECTRICAL ODORL.  AT SAME TIME CABIN VENTILATION FAN STOPPED WORKING.  PILOT IMMEDIATELY NOTICED THAT THE FRONT FAN WAS WORKING, SHUT THE SYS OFF AND OPENED THE OUTSIDE AIR VENT.  ODOR DISSAPATED AS SOON AS THE VENT WAS OPENED.   LANDED AT BASE WITHOUT ANY ADDITIONAL ANOMOLIES OR DEFECTS.  REPLACED BLOWER
