ARJ21 is a regional jet developed by AVIC I Commercial Aircraft Company (ACAC), based in Shanghai, which is a consortium of six companies and aerospace research institutions that carry out the development and manufacture of aircraft. The ACAC consortium was acquired by the Commercial Aircraft Corporation of China (COMAC) in 2009. The aircraft has strong takeoff and climb performance to allow basic airport use with short runways.
The first flight was conducted in November 2008 at Shanghai Dachang Field. The aircraft received CAAC type certification in December 2012. ARJ21 underwent cold weather and weather flight testing in the Inner Mongolia autonomous region in January 2011. The cross wind test from ARJ21 700 was completed in May 2011.
The ARJ21 variant includes the basic ARJ21 700, the extended ARJ21 900 version, the dedicated ARJ21F aircraft carrier, and the ARJ21B business class aircraft.
ARJ21F is a variant of freight ships that can carry five LD7 containers or PIP pallets. The maximum loading capacity is 10,150 kg. ARJ21B is a business jet model built to accommodate 20 passengers.
