Airport spokesman Doug Myers tells local media that maintenance crews believe the smoke was de-icing fluid vapor and the condition cleared quickly after the pilots turned off the windshield heater.
The twin-engine Q400 turboprop carrying 78 passengers had been de-iced before taking off at about 8:30 a.m. Monday.
The pilots reported the situation under control before they landed. Mechanics were checking out the plane. The flight is operated for Continental by Colgan Air.
