WASHINGTON/MONTREAL (Reuters) – Canada’s Bombardier Inc (BBDb.TO) expects to complete the final certification testing of its smaller new CSeries narrow-body commercial jet by the week of Nov. 23, a key milestone toward the plane being certified, four sources briefed on the plan said. The Montreal-based manufacturer declined on Thursday to confirm the testing schedule, but said it still expects certification of the 110-seater CS100 by year’s end, followed by the jet’s entry into service in the first half of 2016.
