The Comac C909, originally known as the ARJ21 Xiangfeng (Chinese: 翔凤; pinyin: xiángfèng; lit. 'Soaring Phoenix'), is a 78–90 seat regional jet manufactured by the Chinese state-owned aerospace company Comac. Development of the ARJ21 began in March 2002, led by the state-owned ACAC consortium. The first prototype was rolled out on 21 December 2007, and made its maiden flight on 28 November 2008 from Shanghai.
It received its CAAC Type Certification on 30 December 2014 and was introduced on 28 June 2016 by Chengdu Airlines. The ACAC consortium was reorganized in 2008 as part of Comac and the jet was rebranded as the C909 in November 2024. It features a 25° swept, supercritical wing designed by Antonov and twin rear-mounted General Electric CF34 engines.
By 2025, 172 airframes had been delivered.
