From the article: "Formerly known as the CSeries, the 110-130-seat A220 was designed by Canada’s Bombardier (BBDb.TO) and was one of the first to adopt the new Pratt & Whitney technology. Bombardier sold the program to Airbus last year due to heavy losses."
If I recall they sold a very good product for a dollar because of extremely anticompetitive and monopolistic abuse by Airbus and Boeing that would have made Rockefeller blush. If bombardier was an American company I think the DOJ would have come down hard on Airbus and Boeing. But they can't be expected to protect foreign competition.
I don't recall any of the abuse coming from Airbus. Because of all that hubbub with Boeing resulting in US tariffs, the A220 is now manufactured in Alabama by Airbus.
Almost none came from Airbus. Really you could almost say they came to Bombardier’s aid.
Buying a billion dollar product for $1 is a funny kind of aid. But yes, Boeing was the aggressor here.
It's worth noting that the problem is with the engine manufacturer's software; the Pratt and Whitney PW1000G family has had issues on the other planes it's on, namely the A320neo and Embraer E-Jet E2.
