Cessna CE-425 Corsair I



In November 1977 Cessna initiated the design of a new pressurised aircraft and the prototype flew for the first time on 12 September 1978. The aircraft combined the airframe of the Model 421 Golden Eagle with two Pratt & Whitney of Canada PT6A turboprop engines. Other features included the dihedral tailplane of the Model 404.
The new aircraft was introduced in 1980 as the Cessna Model 425 Corsair. Like the Model 421, the Corsair offered six/eight seats in varying. The Corsair was certified in mid-1980 and first deliveries made in November the same year.

Late in 1982 the aircraft was retrospectively designated and marketed as the Corsair I and 226 had been delivered when production terminated in 1986. The Garrett-engined Corsair II was built as the Model 441.

A 400 lb gross weight increase is possible for the Corsair when owners fit the later standard stronger wheels and change tyres from 8 to 10 ply. On completing these changes they now have a Conquest I and the original big brother becomes Conquest II.
