About the Cessna 425 Conquest I
Type certificated 1980
Overview
The Cessna 425 Conquest I, sold as the Corsair from its 1980 introduction until a 1983 rename, is Cessna’s entry cabin-class turboprop twin. It pairs the wide-oval 400-series Cessna cabin with two Pratt & Whitney Canada PT6A-112 engines flat-rated to 450 shaft horsepower, a 5.0 psi pressurisation differential, and the docile handling that made it a popular first turbine for owner-pilots. Despite a strong family resemblance to the piston Cessna 421 Golden Eagle, the 425 is a distinct airframe built around the PT6.
For a buyer, the 425 is the natural step up for an owner-pilot moving beyond a pressurised piston twin into turbine ownership, without the workload or running cost of a faster turboprop. It cruises near 260 knots and seats up to eight on a useful load over 3,200 lb, at a direct operating cost the catalogue models near $1,045 per hour, the lower rung of cabin-class turbine economics. It rewards an owner who wants PT6 reliability and cabin-class comfort and will take on the fixed-cost step, insurance, recurrent training, and the structural SID inspections, that turbine ownership brings.
Key Features for GA Buyers
- Approachable first turbine. The 425 is known for honest, predictable handling without the high-workload quirks of faster turboprops, which is much of why it became a common piston-to-turbine step-up.
- Cabin-class comfort. It shares the wide-oval fuselage with the 400-series twins, with club seating and a 5.0 psi differential that holds a sea-level cabin to roughly 11,000 feet.
- PT6 durability. The PT6A-112 carries a 3,500-hour TBO and the deep parts and overhaul network of the widely-fielded PT6 family.
- Blackhawk upgrades. The -135A engine conversion is a popular path to higher cruise speeds and improved climb for owners who want more performance from the airframe.
Trade-offs
- Confused with the Conquest II. The Cessna Conquest II (Model 441) is a different and faster airplane on Garrett TPE331 engines, with higher speed and meaningfully higher maintenance cost; the shared name regularly misleads buyers.
- SIDs exposure. Like other vintage Cessnas, the 425 is subject to Supplemental Inspection Documents, mandatory structural inspections that can be expensive and that belong in any pre-buy budget.
- Turbine step in fixed costs. Insurance, recurrent training, and shop rates all rise moving from a piston twin to a turboprop, even though the PT6’s reliability offsets part of that through the engine reserve.
