|A Lancair IV-P, with a non-standard four-bladed propeller|
|Status||Production completed 2012|
Production of the aircraft kit was ended in 2012.
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 hp (261 kW) at sea level and capable of operating altitudes as high as 29,000 feet.
By the fall of 2011 110 Lancair IVs and 250 IV-Ps had been completed and were flying.
In July 2016 the company announced it would be selling the older Lancair lines of aircraft to concentrate on the Lancair Evolution instead. Once the transition is complete the company will change its name to the Evolution Aircraft Company.
In 2014, Bill Harrelson piloted a Lancair IV setting a world speed record for solo flight between the earth's poles for an aircraft under 3,000 kilograms (6,600 lb) in a 175-hour-long series of flights. The flight also broke a record from Fairbanks, Alaska to Kinston, North Carolina. The aircraft was modified to hold 361 U.S. gallons (1,370 L; 301 imp gal) of fuel.
- Lancair IV
- Unpressurized four seat kit-plane, powered by a 350 hp (261 kW) Continental TSIO-550 engine
- Lancair IV-P
- Pressurized four seat kit-plane, powered by a 350 hp (261 kW) Continental TSIO-550 engine
- Lancair Propjet
- Pressurized four seat kit-plane, powered by either a Walter or a PT6 Pratt & Whitney turboprop, that can achieve cruise speeds in excess of 300 knots (556 km/h) at altitudes up to 30,000 feet (9,140 m).
- Lancair Tigress
- A proposed pressurized version using the 600 hp (447 kW) Orenda OE600 V-8 engine, giving it a cruise speed of 405 mph (652 km/h). The engine was later cancelled and consequently only prototypes of the aircraft were completed.
On February 3, 2012, Steve Appleton, CEO of Micron Technology, Inc., was killed while attempting an emergency landing in a Lancair IV-PT turboprop at the Boise Airport in Boise, Idaho, moments after takeoff. He had aborted a take off a few minutes earlier.
