China National Aviation Corporation
12 examples were ordered by China National Aviation Corporation (CNAC) but only ten production examples were built. All but one was then registered in the US, as many aircraft exported to the CNAC were, however only one example made it to China, which it did in 1930, and it may not have entered CNAC service. One of the ten was lost on its first flight (serial 1006) and its registration was transferred to the next aircraft built.
