The crashed plane is an ERJ-190 jet manufactured by Brazilian aerospace conglomerate Embraer with a maximum passenger capacity of 108.
In its Rio de Janeiro headquarters, Embraer said Wednesday it is sending a team of specialists to Yichun to help investigate the crash.
In a terse statement, the company said it "extends its profound condolences and wishes for recovery to the families and friends of those lost or injured in the accident".
About 30 ERJ-190 jets are in service in China. Five are operated by Henan Airlines and 25 are operated by Tianjin Airlines.
In the past, technical problems propped up among Chinese carriers using the ERJ-190 jets.
Last June, a work-shop was called upon by the CAAC to discuss with domestic carriers problems concerning the imported ERJ-190 jets.
Cracks of the turbine plates and erroneous information displayed in the flight control system were among the most prominent problems, the workshop notes show.
China is one of the world's largest aircraft consumer markets. An industry report conducted by Aviation Industry Corporation of China in 2008 shows that China needs to add 3,815 aircraft, including 2,822 large jets, to its civil aviation fleet before 2027.
Tuesday's crash ended China's remarkable air travel safety record of about 2,100 days -- or 69 months -- without accidents.
In November 2004, a CRJ-200 jet, owned by China Eastern Airlines, crashed shortly after take-off into a park in Baotou City, Inner Mongolia Autonomous Region, killing all 53 people on board and two others on the ground.
