Aircraft Model Overview (Reference only)

The Piper PA-24-180, known as the Comanche 180, is a four-seat, low-wing retractable single and the entry point to Piper's respected Comanche line. Introduced at the end of the 1950s, it broke from Piper's earlier fixed-gear designs with a clean, efficient airframe and a laminar-flow wing. It earned a lasting reputation as one of the most efficient and capable travelers in its power class. Power comes from the Lycoming O-360, a four-cylinder engine rated at 180 horsepower, typically driving a constant-speed propeller. So equipped, the Comanche 180 cruises around 115 to 125 knots and climbs at roughly 910 feet per minute, delivering speed and range that meaningfully exceed comparable fixed-gear singles thanks to its retractable gear and aerodynamically clean design. The all-metal airframe combines a low laminar-flow wing with retractable landing gear and a sleek profile that underpins its cruise efficiency. The retractable gear and constant-speed propeller add systems complexity relative to simpler singles, so the type rewards disciplined checklist use and proficiency. Handling is stable and pleasant, well suited to instrument and cross-country flying. The cabin seats four with comfortable accommodations and useful baggage capacity, and the type's efficient wing gives it strong range for its class. Panels vary widely by aircraft, from original analog instruments to modern IFR avionics and autopilot upgrades on well-kept examples. Useful load, fuel options, and center-of-gravity limits should be verified per airframe. In the used market the Comanche 180 is valued for its speed, efficiency, and range at modest horsepower, supported by an active and knowledgeable owner and type community. It competes with other retractable singles on cruise economy rather than cabin size. Because the type is out of production, landing-gear condition, AD compliance, corrosion status, and parts-support history are central to valuation. Overall, the 1961 Piper PA-24-180 offers efficient, capable four-seat travel with speed and range beyond its horsepower, making it a rewarding choice for proficient, instrument-rated owners. It best suits pilots prepared for complex-aircraft ownership and the type-specific maintenance and inspection commitment the Comanche line requires.
