The Cessna 425, known as the Corsair and later as the Conquest I, is an eight-seat American pressurized turboprop twin-engined light aircraft.

The 425 was introduced in 1980 and was a derivation of the Cessna 421, powered by two 450 hp (336 kW) Pratt & Whitney PT6 engines.

"[1][2][3] The 425 was very easy to fly and was noted by reviewers for its spacious cabin with large windows for good visibility and comfortable seats.

[1][2][3] The original Corsair was developed into the Conquest I by customer demand for more cabin space and a higher maximum takeoff weight.

Earlier model Corsairs can be upgraded to the Conquest I standard with factory-provided modification kits.
