The Cessna 441 Conquest II is a twin-turboprop built from 1977 to 1986. Registry data lists 8 to 11 seats; executive layouts typically seat six or seven. Library figures show a 7255 lb max takeoff weight and 3155 lb useful load. Buyers should focus on the tail-fix history, engine type and inspection status.
- 362 were built. An in-flight tail failure on the sixth airframe led to two groundings and a redesigned horizontal tailplane (AD 79-19-13).
- Most of the fleet has the Dash 10 (Honeywell TPE331-10) conversion: 5,000 hour TBO, about $175,000 per engine overhaul.
- A 2008 review put good examples at $1.2 million to $1.7 million, with variable operating cost of $1,111.31 per hour.
- Library figures: stall 76 kts clean and 60 kts landing; takeoff over 50 ft takes 2332 ft.

Safety notes
- CASA AD/TPE 331/59: certain TPE331 electronic engine controls caused uncommanded power increases. Confirm the listed EEC part numbers were replaced.
- ATSB AO-2007-030: a TPE331-8 failed in flight at FL210 after a compressor bearing failure. Review oil analysis and chip detector history.
- Cessna's SID has no final FAA approval and no AD. Compliance is an owner's election, so ask what inspection status the aircraft has.
