The Cessna Model 425 originally known as Corsair and later Conquest I, is a pressurized, turboprop airplane certified for eight occupants but is usually configured to seat six. Its engines are the Pratt & Whitney PT6A-112 manufactured by the Pratt & Whitney Canada. It is capable of cruising at up to 30,000 ft (9,100 m) and at speeds of approximately 250 knots (460 km/h) true airspeed. It is derived from the Cessna 421 twin-piston-engine airplane. Design work on the Corsair began in 1977, first flight was on September 12 1978, and first production deliveries took place in November 1980.^[1] Cessna produced 236 425s from 1981-1986. Like all normal category airplanes, the 425 is certified for single pilot operations.

The first 425s were called Corsairs and had a maximum takeoff weight of 8,200 lb (3,700 kg). The Conquest name originally belonged to its larger turboprop sibling, the Cessna 441, which was powered by the Garrett AiResearch TPE-331 engine. Cessna then issued an upgrade to the 425 Corsair's landing gear that increased the maximum takeoff weight to 8,600 lb (3,900 kg) and started calling the airplane the Conquest I. The original Model 441 Conquest became the Conquest II. It is believed all the Corsairs had their landing gear converted and so they all became Conquest Is, making the Corsair extinct in the US. The two Conquest models were as far as Cessna ever got to creating a family of turbopropeller airplanes such as the King Airs marketed by Cessna's competitor Beechcraft.
