Boeing has filed a petition with the US Commerce Department complaining that Canada's Bombardier is selling its CSeries passenger jet in the United States for less that it costs to make them. The US aerospace giant asked the Department's International Trade Commission on April 27, 2017 to look into Bombardier's "illegal and unfair business practices" and impose anti-dumping duties on the sale of those airplanes.
