In safety critical environment, you'd better have done your FMECA and designed the system to be "fail-safe". The problem with the 737-Max is that it wasn't.
Fail-safe doesn't mean "no failures" or "no breakages". It means that when they happen (and they will), the system fails in a way that is safe.
QA "gates" in terms of the "throw it over the wall to QA and they will test it in all possible scenarios to ensure quality" is different to QA "gates" that are "throw all of the failure modes that have been identified as dangerous and ensure that the system fails in a safe manner."
That can be part of a CI/CD pipeline in exactly the same way as in the web/cloud world, including generating all of the necessary documentation and evidence for ISO etc standards.
