The Cirrus SR22 is a single-engine, originally four and later five-seat, composite aircraft, built by Cirrus Aircraft starting in 2001. It is a more powerful version of the Cirrus SR20, with a larger wing, higher fuel capacity, and a 310 horsepower (231 kW) engine. It is extremely popular among purchasers of new aircraft and has been the world's best-selling single-engine, four-seat aircraft for several years.
The SR22 was certified in November 2000 and is a higher-powered version of the earlier SR20. The SR22 is a low wing cantilever monoplane of composite construction with tricycle landing gear, featuring a castering nose wheel and steering via differential braking on the main wheels. It is powered by a nose-mounted 310 hp (230 kW) Continental IO-550-N piston engine. The four-seat cabin is accessed through a door on each side.
Cirrus introduced the "SR22 Turbo" in 2006. This was factory installation of a Tornado Alley turbonormalizing upgrade kit installed under a Supplemental Type Certificate. It features twin turbonormalizers and twin intercoolers
