When your literal job is to test critical safety features, yes, you can be blamed for failing at it. Especially when people died because you knowingly failed at your job.

What's next, not blaming architects for designing an unstable building that crashes down? Not blaming a chemical factory's security inspector for OKing dumping of toxic waste into a river?

From experience with government contracts, aircraft certifications, and listening to directors speak, they will tell people whatever needs to be said to get the airplane to pass a final check to get a certification.

One exchange I overheard with some details changed: >you will get a warning light here but this is the end of the fiscal and we need to ship airplanes. It will break on landing then take one week to get the replacement part and we have the maintenance contract anyways. By then we will do the work to fix the issue before anyone else actually flies this aircraft. You can retest it before final delivery and you will also get a bonus or we have more test pilots who hate being drone pilots.
