About the Lancair PropJet IV

The Lancair IV-P represents the pinnacle of amateur-built high-performance aviation, holding the distinction of being one of the fastest piston-single aircraft ever certified in the Experimental category. Introduced in the early 1990s by Lancair International, this pressurized four-seat composite speedster was designed for owner-builders seeking near-turboprop performance at piston operating costs. With a cruise capability exceeding 300 knots true airspeed at altitude and a service ceiling above 25,000 feet, the IV-P routinely outpaces many light twins and can maintain cabin pressurization equivalent to 8,000 feet while flying in the flight levels.

Built entirely from carbon fiber and epoxy composites, the IV-P features a sleek low-wing design optimized for speed, typically powered by a Continental TSIO-550 engine producing 350 horsepower. The aircraft's performance envelope is genuinely remarkable for a single-engine piston: owners report block speeds of 280-320 knots in cruise, with range exceeding 1,200 nautical miles. However, this performance comes with demanding handling characteristics: the IV-P has a well-documented reputation for requiring proficient stick-and-rudder skills, particularly during approach and landing where its clean aerodynamics and relatively high wing loading demand precise speed control.

The type has attracted a dedicated community of experienced pilots and builders, many of whom are business owners and professionals seeking the ultimate in personal transportation efficiency. While the kit-build process typically requires 2,000-3,000 hours of construction time, the result is an aircraft that delivers jet-like point-to-point times at a fraction of the operating cost. The IV-P remains in production through Lancair's successor companies, with ongoing support for the existing fleet.
