The root cause was Boeings profit motivated decision to mount an oversized heavy engine on an incompatible airframe thereby creating a dangerous inherent instability under certain conditions. Everything else is just consequential and flows from that root cause.I agree too.
However, I think the focus on Boeing and the FAA is allowing other other major failings to go unresolved. For example, go back to the first accident, Lion Air 610. The flight prior to the crash almost ended in disaster. MCAS kicked in and that disaster was only averted thanks to an off duty 3rd pilot sitting in the flightdeck jumpseat suggesting that the auto trim should be disconnected. It seems that how that major incident was dealt with post flight was blatantly wrong. The captain seems to have reported it as a relatively minor problem. Thereafter that aircraft should not have been released for service by the engineers, nor accepted for service by the captain of flight 610. It seems to me that there ma also be a major corporate culture problem in Lion Air.
When I saw the CEO of Ethiopian strongly defending his pilots it should naturally make me feel positive about him.....but it doesn’t.
Up to this aircraft designs have been continuously improving in terms of safety. Good engineering practices demand that designs allow as much as possible for human failings and imperfect operating circumstances.
A well designed aircraft should be capable of been flown safely by a less than average pilot on a bad day.. if we start creating complex designs that can only be flown safely by top class pilots from top class airlines then global air safety will deteriorate sharply.
