In a calculated move to increase sales, Beech introduced a radical re-design of the Bonanza on September 14, 1959. The aircraft's trademark V-tail was replaced with a conventional straight tail, resulting in a new variant initially dubbed the “Debonair.” The current straight-tail model, the Bonanza 36, was first built in 1968 and is still in production today.
