TYPE: Four-seat lightplane.

PROGRAMME: Development began 1990; mockup revealed at Oshkosh 1994; first flight (N200SR) 31 March 1995; second prototype (N202CD) flown November 1995; FAR Pt 23 certification aircraft (N203FT), designated C-1, made first flight 28 January 1998 after completion of wing redesign to lower stall speed and improve lateral control. By end 1997, the two prototypes had accumulated 1,500 hours of test flying. A second production-standard aircraft (N204CD; C-2) joined the flight test programme on 3 June 1998, committed to trials of fuel and electrical systems and avionics. Recovery parachute trials involved eight deployments, including three for FAA. Late 1998 start of deliveries delayed by decision of avionics supplier, Trimble, to withdraw from general aviation. FAR Pt 23 certification Amdt 47 received 23 October 1998; Transport Canada certification granted in March 2002; first aircraft manufactured to Canadian certification standard delivered 2 April 2002 to Tim Harpell of Toronto. Initial production aircraft first flew (N115CD) 22 March 1999, but lost on followmg day. First delivery (c/n 1005. N415WM) 20 July 1999, at which time 325 on order (although many since upgraded to SR22 orders). Production certificate, to enable Cirrus to carry out its own inspections, awarded 12 June 2000.

CURRENT VERSIONS: SR20: Total 133 delivered to customers by April 2001, when production suspended. MTOW 1,315 kg (2,900 lb).
SR20A: In production from July 2001. Additional 45 kg (100 lb) MTOW; landing light repositioned lower on engine cowling; and optional Goodrich Skywatch and Sandel SN3308 EHSI for traffic information. Upgrades (including MTOW) retrofittable. As described.
SR20 Version 2.0, Version 2.1 and Version 2.2: Upgraded versions available from 2003; launched at EAA Sun 'n' Fun in April 2002. Differ from SR20A principally in having no vacuum instruments and featuring electrical system and avionics packages based on those of the SR22. Version 2.0 has a single-alternator, dual-battery, dual-bus electrical system and features Avidyne FlightMax MFD, single Garmin GNS 430 GPS/com/nav and GNC 250XL GPS/com and S-Tec System 20 autopilot as standard. First delivery in January 2003 to 907th Flight Squadron Aero club at Jameson, Pennsylvania. Version 2.1 adds a dual-alternator electirical system and GNS 430/420 package. Version 2.2 has dual GNS 430s, S-Tec Fifty FiveX autopilot with altitude preselect and Sandel EHSI.
SRV: Basic VFR-only version, introduced at EAA AirVenture, Oshkosh, 29 July 2003, when demonstrator N936CD (c/n 1337) shown. Specification and performance generally as for SR20 except: cruising speed at 75 per cent power 150 kt (278 km/h; 173 mph); range with reserves 634 n miles (1,174 km; 729 miles); max range 865 n miles (1,602 km; 995 miles).

CUSTOMERS: Orders for 552 received by July 2001. Total of 53 delivered in 2001, 105 in 2002, and 86 in the first nine months of 2003. By December 2002, 267 had been registered.
