“Le CSeries est mort enterré, selon Airbus,” proclaimed the May 31 edition of a Montreal newspaper. Translation: “The CSeries is dead and buried, according to Airbus.” The headline was based on comments made by Airbus CEO Tom Enders to a French magazine about Bombardier’s fledgling 110- to 149-seat jet. Airbus executives have been claiming for months that their company’s introduction of a new engine option (NEO) for the A320 narrowbody voids the business case for the CSeries. Enders also wished Bombardier President Pierre Beaudoin “good luck” working with his Chinese partners, who are slated to supply the CSeries fuselage and co-market the jet with Comac’s new C919 narrowbody.

So there must have been more than a little satisfaction at Bombardier’s Montreal headquarters when—24 hours later—the company announced an end to a 15-month drought in CSeries orders. Braathens Aviation, a regional aircraft operator in Sweden, has agreed to buy 10 of the five-abreast jets, bringing the program’s total to 100 firm orders. Previous orders have come from Lufthansa, Republic Airways and Dublin-based Lease Corp. International.

While the new deal is hardly a blockbuster, it gives the project some much-needed momentum as the industry heads for this month’s Paris air show. “We believe there is a strong likelihood of additional CSeries orders in Paris,” says National Bank Financial analyst Cameron Doerksen.

They could not come soon enough. Doerksen notes that the company is only one-third of the way to its goal of 300 orders by the CSeries scheduled service entry in late 2013 and 350 aircraft short of the sales he projects are required for the project to break even. Airbus officials make a good case with their argument that the A320NEO has nullified some of the CSeries’ efficiency advantage. And the competition will grow even fiercer if Boeing opts to offer a re-engined 737. “Everybody is expecting triple-digit A320NEO orders, as well as the possible launch of an A319NEO, at Le Bourget,” says Teal Group analyst Richard Aboulafia. “Paris might just be a repeat of last year's Farnborough show, where Bombardier was conspicuous for its absence of orders.”

Bombardier executives say they are in advanced talks with seven to 10 potential CSeries buyers. JPMorgan analyst Joseph Nadol believes that list includes large carriers in Europe, Asia and the Middle East. And while he is not sure those deals will be closed by the time the air show opens on June 20, Nadol believes demand will pick up. “The CSeries is very well positioned from an operating cost standpoint,” he says.

Ten orders from a little-known Swedish airline are unlikely to silence the skeptics. Even if Airbus and Boeing are unable to quash the startup program, Bombardier must still pull off the most advanced aircraft development it has ever launched. As for Paris, Bombardier Aerospace President Guy Hachey is coy when asked about the prospect for announcing further orders. “You'll have to follow us closely.”
