The $2.6 billion needed to develop the CSeries will come in roughly equal shares from Bombardier, principal suppliers and the Canadian and UK governments. Ottawa is providing loans worth $350 million, while $118 million will come from Quebec and £155 million ($310 million) from the UK and Northern Ireland.
"We're confident that what we've put in place with the Northern Ireland and UK governments is WTO compliant, and it will need to be approved by the European Commission," says Bombardier chief executive Pierre Beaudoin.
Around two-thirds of CSeries production work is being farmed out to risk-sharing partners and suppliers, but final assembly will be performed at Bombardier's Mirabel, Montreal factory.
"Bombardier is doing the design and integration work and two of our sites are contributing some of the manufacturing, those being Saint Laurent and Belfast," says CSeries programme management director Benjamin Boehm. "But the majority of the rest of the airplane is external partners.
"When you look at it from the bill of materials of the airplane, definitely over 60% of it - probably much higher than that even - is not within Bombardier."
The wings will be developed and manufactured by Bombardier in Belfast, while the aft-fuselage and cockpit section will be produced in Saint Laurent.
Shenyang Aircraft, part of China Aviation Industry 1, is taking responsibility for the centre fuselage, centre wing box and doors for CSeries, while C&D Zodiac has the cabin, Rockwell Collins the avionics, Parker Hannifin the fuel and hydraulics systems and Liebherr-Aerospace Toulouse the air management system.
