Three all-new composite, four-seat, IFR singles are available on the U.S. market: The Diamond DA40 Star, the Cirrus SR-20 and the Lancair Columbia 300.

AVweb’s Dave Higdon managed to put the three through their paces – all in the same week. In this second pilot report of a four-part series, he tackles the Lancair Columbia 300.
