## Discrepancy

(CAN) THE FLIGHT CREW REPORTED SMOKE & A SULFURIC ODOR IN FLIGHT.  THE SMOKE & ODOR DISSIPATED QUICKLY AFTER RUNNING THE QR.  THE FLIGHT CONTINUED UNEVENTFULLY.  UPON ARRIVAL MX FOUND THE RECIRCULATION FAN HAD FAILED.  THEY WERE ABLE TO CONFIRM A BURNT SMELL COMING FROM THE FAN AT REMOVAL & ALSO FOUND THE RECIRCULATION FAN CB POPPED.  THE CREW REQUESTED REPLACEMENT OF THE FAN INSTEAD OF DEFERRAL BY MEL DUE TO THE INFLIGHT SMOKE EVENT.
