Cessna 350 Aircraft (Corvalis)

The Cessna 350 (marketed as the Corvalis, originally the Columbia 350) is the naturally aspirated version of Cessna's composite high-performance single — the same airframe as the 400/TTx but with a Continental IO-550-N (310 hp) rather than the 400's turbocharged TSIO-550. The result is a fast, composite, fixed-gear single that gives up cruise speed to the 400 in exchange for naturally aspirated simplicity and lower operating cost.

Heritage: Designed and initially produced by Columbia Aircraft as the Columbia 350, acquired by Cessna and rebranded Corvalis, later discontinued. As a discontinued model, parts and avionics updates depend on the aftermarket rather than new Cessna supply.

Composite construction: The 350's carbon-composite airframe contributes to its high cruise speed relative to engine size. Composite maintenance requires inspectors trained in the material; any prior damage and repairs must be fully documented — undocumented composite repairs reduce resale value and may affect airworthiness.

Versus the Cessna 400 (TTx): The 350 is the same airframe without the turbocharger — simpler engine, lower fuel burn per hour, and lower cruise altitude. The 400's TSIO-550 provides higher cruise and high-altitude capability; the 350 is more economical for operations below the turbocharger's useful range. For buyers who rarely need the high flight levels, the 350's IO-550 is meaningfully simpler to maintain.

Avionics: Most Cessna 350/Corvalis aircraft carry Garmin G1000 avionics. Confirm software currency and any navigator integration when comparing examples.

Buy it if: you want a fast composite single at naturally aspirated economics — and your missions stay below the turbocharger's altitude advantage. The 400/TTx wins for high-altitude and higher cruise; the 350 wins on maintenance simplicity and per-hour cost for lower-altitude operations.
