I have read that self-issuance of airworthiness certificates has been normal since the 1950s. Given that, I don't think the issue is due to regulatory corruption but an issue at Boeing which has (hopefully) been resolved.
"The issue" at Boeing is obscene levels of financialization which, of course, has not been "solved."
