1966 Beechcraft DuchessMulti-Engine Piston Aircraft • Sioux City, IA, USA
This 1966 Beechcraft Duchess, registered as N670WB, presents a compelling opportunity with a low total airframe time of 2,030 hours and a recent, comprehensive mechanical refresh. Both engines and propellers show only 27 hours since their major overhauls in 2025, and the aircraft has just completed its annual inspection in March 2025. It has no known damage history, with a 1,000-hour gear inspection completed in November 2021. The aircraft is equipped with "dial-in" turbochargers, which allow the engines to operate in either normally aspirated or turbocharged mode; both turbos were overhauled less than 300 hours ago.
