What do you mean attempted? Boeing successfully slaughtered 346 people with their negligence.



And they didn't even get any new regulations written that I've seen. The hand wheels for the horizontal stabilizer trim became too hard for average pilots to physically operate if the aircraft is going too fast and out of trim far enough (even without being outside the safe operating envelope). There was no regulation limiting how much force the trim wheels can need while within the operating envelope. AFAIK, there's still no such regulation. So the "fixed" 737 Max models didn't change the hand wheels, meaning the physical backup in case of a trim runaway might not actually be usable. Yet they certified it without changes, because there's no regulation saying that the safety backup wheels have to be physically usable by average pilots in the event the primary powered system fails!
