Engineering case history from Twitter. If this is correct then we have another in a long list of lax regulation disasters.

Indeed, Boeing has an FAA approval problem:

FAA employees warned... that Boeing Co. had too much sway over safety approvals of new aircraft..."

DOT auditors confirmed the FAA hadn’t done enough to "hold Boeing accountable..." According to The Seattle Times, Boeing had understated the power of the flight-control software in a safety analysis submitted to the FAA. Specifically, the analysis failed to consider how the system could reset itself each time a pilot responded -- in essence, gradually ratcheting the horizontal stabilizer into a dive position... The newspaper also quoted unnamed FAA technical experts who said managers prodded them to speed up the certification process as development of the Max was nine months behind that of rival Airbus SE’s A320neo...

So in a nutshell, the bigger, heavier more efficient engines were placed further forward and this moved the center of gravity of the plane forward and destabilized the plane.

So the real problem facing the 737 MAX is stability - and this is what needs to be fixed. Not software to cover up the real problem.
