Buying a Used Cessna Conquest I
Buying a Cessna Conquest I centres on its turbine engine(s) — time to overhaul, hot-section history and any engine maintenance program — alongside airframe hours and cycles.
What to check before buying
- Turbine engine status — hot-section and overhaul time, trend monitoring and whether the engine is on a maintenance program.
- Airframe hours & cycles — high-utilisation turboprops accumulate cycles quickly; cycles can matter more than hours.
- Equipment — cargo pod, floats/amphibian gear, de-ice and avionics all affect value.
- Corrosion & logbooks — continuous records and a corrosion inspection, especially on float or marine-operated aircraft.
- Pre-buy inspection — commission an independent pre-buy by a type-experienced shop.
