The Cessna 620 was the project of a four-engined business aircraft of the U.S. manufacturer Cessna, Wichita, Kansas.
Construction and history
In the Cessna 620 it was a self-supporting all-metal low-wing monoplane with retractable tricycle landing gear and a conventional tail. As drive four Continental GSO -526 were used with reduction gear and charging. An auxiliary turbine in the rear powered pressurized cabin and air conditioning. There were eight to ten passengers. The equipment was designed for unrestricted instrument flight.
Development work began in September 1953, the first flight took place on 11 August 1956. The launch should take place in 1958, the calculated unit price ranged 300000-400000 U.S. dollars. However, for this price you could also already a brand new larger Convair CV 240 or Martin 4-0-4 acquire what the sales prospects could fall sharply. In October 1957, therefore, the project was discontinued. The only prototype with the registration N620E was sold after only 50 hours of flight time and later scrapped.
