Cessna 425
1978 utility aircraft
The Cessna 425, known as the Corsair and later as the Conquest I, is an eight-seat American pressurized turboprop twin-engined light aircraft. Now out of production, it was built by Cessna Aircraft of Wichita, Kansas, between 1980 and 1986.
Design and development
The 425 was introduced as a competitor to the Beechcraft King Air. 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. In comparison to the King Air C90, "the result was an $875,000 pressurized twin-turboprop that could fly 15 knots to 20 knots faster than the C90, cruise 250 miles farther with four passengers aboard and burn 15-percent less fuel ... it also costs $200,000 less to buy."
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.
The original Corsair was developed into the Conquest I by customer demand for more cabin space and a higher maximum takeoff weight. Cessna worked on upgrades that would allow more cabin space and passengers. Essentially, the upgrades increased maximum takeoff weight. The Cessna 441 had previously been called the Conquest but was renamed the Conquest II. Earlier model Corsairs can be upgraded to the Conquest I standard with factory-provided modification kits.
This brief starts where responsible research should: with the source description of “Cessna 425” as 1978 utility aircraft. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as 1978 utility aircraft. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jul 18, 2026. The linked authority identifier is Q1057259. The first chronological checks are 1980 and 1986.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
