Lancair IV
The Lancair IV and IV-P are a family of four-seat low-wing retractable-gear composite monoplanes powered by a 550 cubic inch Continental turbo-normalised piston engine.[2][1]
Development
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.[1]
By the fall of 2011 110 Lancair IVs and 250 IV-Ps had been completed and were flying.[1]
Variants
- Lancair IV
- Unpressurized four seat kit-plane, powered by a 350 hp (261 kW) Continental TSIO-550 engine[1]
- Lancair IV-P
- Pressurized four seat kit-plane, powered by a 350 hp (261 kW) Continental TSIO-550 engine[1]
- Lancair Propjet
- Pressurized four seat kit-plane, powered by a Walter turbine or Pratt & Whitney Canada PT6 turboprop that can achieve cruise speeds in excess of 300 knots (556 km/h) at altitudes up to 30,000 feet (9,140 m).
Accidents
As of March 2010, the NTSB Aviation Accident Database records 19 crashes involving 17 fatalities across all IV variants.[3]
