## Discrepancy

SMOKE IN CABIN REPORTED BY PASSENGERS.  PASSENGERS BELIEVE THE SOURCE MAY HAVE BEEN THE FLOOR VENTS.  PILOTS COULD NOT CONFIRM SMOKE, BUT RETURNED TO FAIRBANKS IMMEDIATELY AFTER DEPARTURE.  CONFIRMED AFT VENT MOTOR AS CAUSE OF SMOKE.  REMOVED BAD MOTOR INSTALLED OVERHAULED MOTOR.  GROUND OPERATIONAL CHECKS IN LOW AND HIGH SATISFACTORY.
