The Lancair IV and IV-P are a family of four-seat, low-wing, retractable-gear, composite monoplanes powered by a 550-cubic-inch (9,000 cm3) Continental TSIO-550 twin-turbocharged piston engine.

[4] The Lancair IV and IV-P were designed by Lancair around the Continental TSIO-550 — a twin turbocharged engine that is capable of developing 350 horsepower (260 kW) at sea level, and capable of operating at altitudes as high as 29,000 feet (8,800 m).

The flight also broke a record from Fairbanks, Alaska to Kinston, North Carolina.

[6] On November 11, 2023 a Lancair IV-P overran the runway at Aero Country Airport (T31) in McKinney, TX.

As of June 2014, the NTSB Aviation Accident Database recorded 20 crashes involving 18 fatalities across all IV variants.
