No idea. When it comes to bad quality controls and processes, the model doesn't matter much so. Also, I have no idea how Airbusbis surveilling and working with Spirit Aerospace compared to Boeing.

We might get the answers soon. If Boeing really wants to buy Spirit we might see Airbus’ exposure. That said, it wouldn’t be unheard them building for each other. Pretty sure Airbus manufactured parts for Boeing and vice versa in the past.
