About the Lancair IV

The Lancair LC41-550FG represents the high-performance evolution of the Columbia 400 line, a composite four-seat single that pushed the boundaries of piston-aircraft speed and efficiency when it debuted in the early 2000s. Built with an all-composite airframe and powered by a turbocharged Continental TSIO-550-C engine producing 310 horsepower, the LC41 achieves cruise speeds around 235 knots, making it one of the fastest certified piston singles ever produced. The design originated with Lancair, was later marketed as the Columbia 400 and Cessna 400 after Cessna's acquisition of the type certificate, and eventually became the Cessna TTx before production ended in 2018. Its sleek, low-drag fuselage and advanced avionics suite made it a favorite among owner-pilots seeking near-turboprop performance without the operating costs.

The LC41's operating envelope is equally impressive: a service ceiling above 25,000 feet, a never-exceed speed of 250 knots, and a useful load that accommodates four adults with full fuel for 1,000-nautical-mile legs. The aircraft's stall characteristics are benign for its performance class, with Vs0 around 60 knots, though its speed and weight demand respect on approach. Fixed gear and a relatively wide track contribute to stable ground handling, while the side-stick control and glass cockpit reflect its modern design philosophy.
