They are screwed. Their entire supply network will unravel unless they are able to cut those suppliers in the next couple of weeks. If you are an Airbust sub and you believe there's shot at gettin dumped are you going to be real anxious to invest more money and risk more of your capital? This move will lead to preemptive dumping and courting of Boeing.
Nothing like cutting your subs off to replace them with those real efficient 28 hour a week French workers,, good luck on getting co-operation with those same subs teaching Airbust employees how they produce those parts on time and at a reasonable cost... that learning curve is nothing to sneeze at... reliability will become a huge issue with any aircraft they're lucky enough to complete and maintenance will be a nightmare with so few to be in service and so much variety in the parts...
Right now those subs are resubmitting billing for past work and warming up their legal teams...
