"We have informed Boeing that we will not take deivery until the 787's have the new modified shaft."

Seems pretty straightforward to me, the client is demanding new shafts. If I buy a new Ferrari, and the crankshaft won't perform, in fact, it fractures on the test drive, I will want a new and different car, not just a replacement crankshaft. The engine would needs be pulled, and all collaterals might be scuffed, or are damaged when the crank lets go.
What about the internals?
Who is the customer, by the way? Al Baker? Qatar? Me and my Family?
Duty of care should be made public, not hushed on the down low. Besides, it is virtually always true that disclosure and honesty work in favor of the principals, in the long run....
