Lancair Propjet Iv

Single Turboprop· 191 globally registered

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. SkyMeter has tracked 42 flights across 18 airframes and 18 operators, with TAB AVIATION LLC the largest observed operator.

Safety in context

The incident rate counts flights with ANY safety event detected by SkyMeter: go-arounds (a routine response, not a failure), unstable-approach gate flags (advisory thresholds), rejected takeoffs (the system working as designed), and runway events. It is NOT an accident rate or fatality rate. For accident statistics, refer to the NTSB Aviation Accident Database (USA) or the Aviation Safety Network. See methodology for what each event type measures.
