'Soaring Phoenix'), is a 78–90 seat regional jet manufactured by the Chinese state-owned aerospace company Comac.

It features a 25° swept, supercritical wing designed by Antonov and twin rear-mounted General Electric CF34 engines.

[12] The first prototype (serial number 101) rolled out on 21 December 2007,[13] with a maiden flight on 28 November 2008 at Shanghai's Dachang Airfield.

[citation needed] The aircraft completed a long-distance test flight on 15 July 2009, flying from Shanghai to Xi'an in 2 hours 19 minutes, over a distance of 1,300 km.

This was the first time a turbofan-powered regional jet independently developed by China had flown abroad to carry out flight tests in special weather conditions.

At the same time, other flight-test aircraft covered more than 30,000 km across Asia, America, Europe, and the Pacific and Atlantic oceans.

Route-proving started on 29 October 2014, and AC105 made 83 flights between ten airports in Chengdu, Guiyang, Guilin, Haikou, Fuzhou, Zhoushan, Tianjin, Shijiazhuang, Yinchuan and Xianyang.

Subsequently, a -900 stretch version was designed to accommodate 115 all-economy seats, similar to the Bombardier CRJ900, Embraer E175-E2 or Mitsubishi MRJ90.

The two airframes were initially delivered to Chengdu Airlines in 2018 in the passenger configuration and were subsequently withdrawn for the CCF program in 2021.

[27] The converted freighters have a maximum payload capacity of 10 tonnes and a range of about 1500 nautical miles (2780 km).

[33][34][35] The ARJ21's development did depend heavily on foreign suppliers, including engines and avionics from the United States.

[39] Members of the ACAC consortium, which was formed to develop the aircraft, will manufacture major framework components of the aircraft: The inflight power source of COMAC C909 is General Electric CF-34 turbofan,[40] which is also widely used on other regional jets like the Mitsubishi CRJ and Embraer E-Jets.

COMAC chose Collins Aerospace Pro Line 21 integrated avionics system (IAS) as their flight deck avionics solution,[41][42]they also supply the FMS-4200 flight management system (FMS) for the C909, which can also be seen on Mitsubishi CRJ550/700/900/1000 regional aircraft and the weather radar.

The C909CCF (COMAC converted freighter) is designed with a maximum payload of 9,467kg and is compatible with PMC, PAG and AKE cargo containers.

[43] The first batch of conversions involves two C909ER [ARJ21-700 ER] aircraft originally built and operated by Chengdu Airlines and returned to COMAC in 2021.

[46] As of 31 August 2018, Comac had 221 outstanding orders, after 23 deliveries to launch operator Chengdu Airlines who put it in service on 28 June 2016.
