The Cirrus SR20 is an American piston-engine, four-or-five-seat, composite monoplane built by Cirrus Aircraft of Duluth, Minnesota.
The SR20 was the first production general aviation aircraft equipped with a parachute to lower the airplane safely to the ground after a loss of control, structural failure or mid-air collision. It was also the first manufactured light aircraft with all-composite construction and flat-panel avionics.

Design and development
The SR20 mock-up was unveiled in 1994. The aircraft first flew on 21 March 1995 and FAA certification was achieved on 23 October 1998. At the time of the airplane's release, the general aviation industry was struggling; the SR20 was one of the first of its kind to earn FAA Part 23 certification in several years. Over a thousand SR20s have been sold since deliveries began in 1999. As of June 2015, more than 6,000 Cirrus aircraft had been delivered, something that no other aviation company has done for decades.
One of the major selling points for the SR20 is its Garmin Cirrus Perspective avionics suite with dual 10-inch (250 mm) or 12-inch (300 mm) screens: one primary flight display (PFD) and one multi-function display (MFD). This provides all standard communication, navigation (GPS and conventional VHF), and surveillance (Mode S transponder) functions. Other avionics features include in-flight weather information and TCAS-like traffic information.
SR20s made from 1999 to 2003 were equipped with traditional analog instruments and a 10" MFD. In July 2003, Cirrus made PFDs standard on the SR20 and faster SR22, pioneering the use of glass cockpits in the light aircraft general aviation industry.
The SR-series remains the only airplane in its class to include side stick flight controls that combine aspects of a traditional yoke handle (this has been referred to in the industry as a "side yoke").
The SR20 and SR22 are equipped with the Cirrus Airframe Parachute System (CAPS), a large parachute that can be deployed in an emergency to lower the entire aircraft to the ground safely. As of 2015, the series has deployed the system 53 times carrying 107 survivors.
On 1 June 2004, the SR20 became the first aircraft to achieve the new European Aviation Safety Agency certificate for aircraft imported into the European Union.
In 2004, Cirrus introduced the SR20 G2 (Generation 2) and in 2008 the SR20 G3 (Generation 3). Both were defined by airframe modifications, G2 by fuselage and G3 by wing/landing gear changes.
In 2012, "60/40 flex seating" was introduced, allowing up to three passengers in the rear with a split fold-down seat arrangement. This five-seat configuration was optional in 2012 but became standard equipment for 2013 SR20 models.
In 2016, Cirrus introduced enhancements to the SR Series, including Bluetooth wireless connectivity, a remote keyless entry, convenience lighting system, and a new easy access door latch, among other interior and exterior improvements.
In 2017, the company introduced the SR20 G6 (Generation 6), with several upgrades to the avionics, new navigation lights and an increased useful load.

Variants
- SR20
- Original version produced from 1999.
- SR20 G2
- Improved variant introduced in 2004.
- SRV
- Introduced at the 2003 EAA AirVenture Convention and brought to market in 2004, the Cirrus SRV was a VFR-only version of the SR20 for the low-end private ownership and flight training market. As such it omitted some standard equipment available on the SR20 such as wheel fairings. For 2008 the SRV model was updated to G3 configuration, with the SR22 wing. Cirrus discontinued the SRV for the 2010 model year.
- SR20 G3
- Introduced in 2007, the "Generation 3" G3 has a lighter wing of greater area, incorporating a carbon-fiber spar. The new wing increased the SR20's cruise speed by 6-7 knots (11-13 km/h). The G3 also added a 50 pounds (23 kg) increased useful load by increasing the take-off weight to 3,050 pounds (1,380 kg), a re-designed main landing gear that is 2 inches (5 cm) taller, giving greater propeller and tail clearance, improved aircraft handling due to increased dihedral, improved aerodynamics including new wing root fairings, new LED recognition lights, improved heat and ventilation, dual-redundant GPS WAAS-certified Garmin GNS 430W comm-navigators (that include a VHF radio and a VOR/LOC/ILS receiver) and an S-Tec Autopilot.
- T-53A
- In 2011, the SR20 was selected for cadet flight training with the 306th Flying Training Group at the United States Air Force Academy and given an Air Force model/design/series (MDS) designation as the T-53A. Twenty-five examples will be purchased to replace the Academy's current stock of 20 leased T-52As by May 2012.
- SR20 G6
- Introduced in January 2017, the G6 model adds a Lycoming IO-390 engine of 215 hp (160 kW), an enhanced Garmin Perspective-Plus flight deck, LED wingtip lights and a useful load increase of 150 lb (68 kg).
Operators
Civil

Accidents
On March 23, 1999, Duluth native Scott D. Anderson was killed in a plane crash while flight-testing the first production model SR20 before it went on sale. Anderson was a pilot, author, engineer and adventurer who served as Chief Test Pilot at Cirrus in the mid- to late-1990s, performing all the inflight test-deployments of the CAPS. His plane, which had not yet been equipped with CAPS, experienced an aileron jam during experimental stress-testing and went down in a field near the Duluth International Airport. Anderson was inducted into the Minnesota Aviation Hall of Fame in 2010 and is often praised as a hero by the local community.
New York Yankees pitcher Cory Lidle and certified flight instructor Tyler Stanger were killed in the 2006 New York City plane crash on October 11, 2006, when their SR20 crashed into the Belaire Apartments located on the Upper East Side of Manhattan. The aircraft struck the north side of the building, causing a fire in several apartments. The accident was the result of high winds and pilot error.
In 2011, the accident record of the SR20 and -22 was the subject of a detailed examination by Aviation Consumer magazine. The review concluded that the series has an overall accident record that is better than average for light aircraft, exceeded only by the Diamond DA40 and DA42. However, its fatal accident rate is much worse at 1.6/100,000 hours, placing it higher than the U.S. general aviation rate of 1.2 and higher than the Diamond DA40 (.35), Cessna 172 (.45), Diamond DA42 (.54), Cessna 182 (.69) and the Cessna 400 (1.0), despite the Cirrus's full aircraft parachute system.
By 2014, the accident rate had been dramatically reduced, with a 2013 fatal rate of 1.01 per 100,000 flight hours. This was attributed to better training, particularly in when to deploy the ballistic parachute system.
By 2015, the accident rate had continued to decrease, with a 2014 fatal rate of .42 per 100,000 flight hours, making it one of the best safety records in the industry. This marked the fewest fatalities in a single year for Cirrus since 2001, and the first year where the number of CAPS deployments (12) exceeded the number of fatal accidents (3).
Between 1999 and 2015 the SR20 was involved in 27 known fatal accidents.
