SEATTLE, May 18 (Reuters) - The U.S. Commerce Department said on Thursday it was launching an investigation into claims by Boeing (NYSE:BA) Co BA.N that Canadian plane maker Bombardier Inc BBDb.TO dumped CSeries aircraft in the U.S. market and is being unfairly subsidized by the Canadian government.
The Commerce probe, which was expected, parallels an investigation by the U.S. International Trade Commission into Boeing's allegations that Bombardier sold 75 CSeries planes to Delta Air Lines Inc (NYSE:DAL) DAL.N last year at a price well below cost. Bombardier has refuted the allegations, and the two sides clashed at an ITC hearing on Thursday.
