While the Beech Model 35 Bonanza was a great success, some customers disliked the unusual two-piece V-tail so Beech built the Model 33 Debonair which was first marketed in 1966 with a conventional tail unit. It had a 225 hp Continental engine but the alternative E33A was available later with a 285hp engine. From 1968 it was renamed the Bonanza 33.
