David Stewart, vice president of consultancy ICF International says even if the C919 doesn't gain traction outside of China, the next aircraft they manufacture will be a success.

"The Chinese don't really worry about 10, or 20 years. It's where will they be in 50 years' time. They are on a learning curve, and it doesn't really matter to them how long it takes. At some point there will be ABC - Airbus, Boeing, Comac," said Stewart, who expects Comac will begin to present genuine competition to Boeing and Airbus in the next two decades.
"They will break out of China with the C919, because they know they have to develop their customer support infrastructure to be able to support planes outside of China," he added.
It wouldn't be a surprise to see C919's flying in Africa, said Stewart. Beijing may make an investment into an African infrastructure project in exchange for orders of the aircraft for example, he said.

"It's all part of a grand experiment to learn how to do this sort of thing, Africa could be a testing ground," Stewart said.
Comac's expansion into the global market, however, won't be without major challenges.
In addition to overcoming negative perceptions over the safety of products produced in the mainland, the company must set up a large amount of infrastructure in order to support its fleet.
"Airlines exist on having a reliable operation. To do that you have to have spares and technical support in the right place, doing that in English, at a distance, they don't have any track record at all on that, so that's their biggest challenge," said Stewart.
