Sale pending. All other offers still welcomed. This amazing CE-425 was just donated to our Missionary organization in Iowa. Last five years was operated part 91 flying 20 hours a month flying employees between Iowa and Mississippi plants for a local manufacturing company. Prior to that it spent a decade as a part 135 aircraft for Lyddon Aero in Kansas. Engines on 8000 hour TBO with MORE program inspections. Recent vibe analysis by Prime Turbines. All phases current included spar cap modification and complete nose to tail deep inspection, tanks resealed, nothing overlooked by Yingling in Wichita ($300,000). Beautiful panel with 600txi, GI-275 backup, 530/430, 330 txp with adsb out. Flightstream 210. GDL69a SXM weather receiver, Active traffic system. STEC 3100 with all servos overhauled at install. This is an exceptional aircraft for the age and an excellent first turboprop for someone stepping up or a corporation needing air-conditioned, pressurized comfort while cruising with PT-6's in the flight levels at 255 knots.

About the Cessna Conquest I
The Cessna Conquest I (model 425) is the smaller of Cessna's two pressurised twin-turboprops — a cabin-class aircraft powered by two Pratt & Whitney Canada PT6A turbines, offering turbine reliability, a comfortable pressurised cabin and high-altitude capability. It bridges the gap between piston twins and larger business turboprops, cruising around 270 knots. See the live price range and median above for the Cessna Conquest I and 425 listings currently on the market.
Produced 1980–1985.
