The C919 is China’s first domestically developed narrow-body passenger jet, manufactured by the state-run Commercial Aircraft Corporation of China (COMAC). 

This development marks a significant step toward greater technological independence for China and may influence the global aviation market. Although, the South China Morning Post (SCMP) pointed out that it still faces tough competition from long-established players like Boeing and Airbus. At present, there are only 18 C919s operating domestically, and none are certified outside of China. 

Though COMAC has secured hundreds of orders from the nation’s top three Chinese airlines, SCMP reporter, Frank Chen, said that the C919 remains heavily reliant on Western suppliers, particularly for critical components like its General Electric engines.

Chen said COMAC would likely plan to keep using these foreign-made parts, as Chinese alternatives still lagged in fuel efficiency and reliability. Manufacturing challenges also make a full switch unlikely in the near term. For now, using proven Western components is seen as the more practical path, especially to meet international certification standards. However, this dependence is viewed “as a vulnerability” by some Chinese officials, especially in the context of U.S.-China trade tensions.

Despite this, COMAC is focused on integrating global supply chains – similar to how Apple assembles smartphones. For now, the aircraft’s primary market will likely remain domestic, but expansion into Southeast Asia and other countries recognizing Chinese aviation certification could follow. If COMAC can capture even 30–50% of China’s annual aircraft demand – estimated at 100–200 planes, it could secure a solid foothold as a key player in the aviation market.
