The Beechcraft Model 40A was an experimental twin-engined aircraft based on the Beechcraft Bonanza. Only one prototype was built in 1948. It featured a unique over/under arrangement of two 180 hp Franklin aero engines mounted on top of each other and driving a single propeller. The plane had a different engine cowl than a standard Bonanza and the nose gear could not fully retract, but otherwise it greatly resembled the production Bonanzas of the time.
Certification rules demanded that a firewall be fitted between the two engines, however, thus stopping development.[1] The status of the prototype is unknown.
