1979 Beechcraft A-60 Duke used

The Beechcraft A-60 Duke is a twin-engine light aircraft manufactured by Beech Aircraft Corporation (now a part of Textron Aviation) from 1973 to 1982. The Duke was designed to replace the Beechcraft Baron, with a larger cabin and increased performance. Powered by a pair of Continental Motors TSIO-520-A engines, the Duke was capable of a cruising speed of up to 235 knots (270 mph).
The Duke featured a retractable landing gear and a pressurized cabin, and was designed to appeal to the business traveler. The aircraft was well-equipped with modern avionics and instrumentation, including a color weather radar and a digital autopilot. The Duke was popular among business travelers and charter operators, and was also used for air ambulance and law enforcement operations.
Despite its popularity, the Duke was eventually replaced by the Beechcraft King Air, which offered superior performance and range. The last Duke was produced in 1982, and most of the surviving aircraft are now operated by private pilots and charter operators.
