## Discrepancy

SMOKE IN THE CABIN AT ROTATION. AN EMERGENCY WAS DECLARED WITH THE TOWER AND THE AIRCRAFT RETURNED TO KOMA. THE AIRCRAFT LANDED WITH NO ISSUES AND WAS GREETED BY THE FIRE DEPARTMENT ON THEIR RETURN. THE FIRE DEPARTMENT INSPECTED THE AIRCRAFT AND FOUND NO SIGNS OF ANY HOT SPOTS. POSSIBLE CAUSE IS THAT DE-ICING FLUID GOT INTO THE SYSTEM FROM THE ENGINE INLET.
