Cessna 425 Conquest airplane model. The Cessna 425 was introduced to the Cessna model lineup from 1980. Based on the Model 421 Golden Eagle, it differs from its donor aircraft in having turboprop engines (in this case PT6As). Design work on the Corsair began in 1977, first flight was on September 12 1978 and first production deliveries took place in November 1980.
From 1983 Cessna renamed the Corsair the Conquest I, while the Conquest became the Conquest II. Production of both ceased in 1986.
