That's not how FAA submitted documentation works. Just don't sign it if you have any questions. I never signed anything until I had personally verified the data and/or the code for myself.

If there are young engineers out there reading this, please disregard these people telling you that you are indemnified. Talk to a lawyer yourself if you don't believe me, but please don't follow the advice these people are laying out.

Signing off on something you know to be untrue and submitting that to the FDA or FAA as part of an approval process is a federal crime. Not only that, but the way our lawyers explained it to us, each time we sign off on something that turns out to be false, it counts as one count of lying to the federal government. And, no, you being an employee who was directed to sign does not absolve you from culpability.

Any 1L knows that you cannot, under any circumstances, contract away criminal liability. You are always liable for the actions you take that turn out to be criminal.

Again, don't believe me telling you that you will be committing a crime if you sign off on a fix or design that turns out to be bunk. Definitely don't believe these guys telling you will be protected if you sign off. Go talk to an attorney for yourself. You'll find what I'm saying is true. You want to find that out before you sign off on a fix or a design. Not after. Believe me.

Just some fatherly advice from an older engineer to younger ones. Please protect yourselves.
