if there's a safety concern that should be handled by regulation
Regulation won't detail what a company does to that level. They might say something like "fasteners shouldn't come loose" but it wouldn't have a torque spec.
If whatever it is is that critical to the safe operation it should be publicly documented so that third parties...
That would run face first into proprietary info and corporate classified info.
I doubt they'd announce charges without the plea if it was guilty. Adams and his lawyers would have been in communication with the prosecutor to discuss plea deals. Had they come to an agreement the headline would instead read like "Adams to plead guilty to [insert crimes here]."
