The aircraft has retractable tricycle landing gear and a pressurized cabin. The two piston engines are turbocharged and the turbochargers also pressurize the cabin with bleed air. The development of the Beechcraft 60 began in early 1965, and it was designed to fill the gap between the Beechcraft Baron and the Beechcraft Queen Air. On December 29, 1966, the prototype made its first flight. On February 1, 1968, the FAA issued the type certificate. Distribution to customers began in July 1968. The passenger cabin is fitted with club seating and entry is by means of a port-side airstair entry door in the rear fuselage. The Beechcraft A60, which came onto the market in 1970, represented an advancement over the Baron, with an improved pressurized cabin utilizing advanced bonded honeycomb construction, lighter and more efficient turbochargers, and improved elevators. The last variant, the B60, was introduced in 1974. The interior arrangement was renewed and the engine efficiency again increased by improved turbochargers. The Beechcraft 60 was, despite its very good performance, only a moderate seller, principally because the complicated technology demanded a high expenditure on maintenance. Production was stopped in 1983. For more information, including the turbine powered model, click here. Piston Engined. Turbine Powered
