The previous crew counteracted MCAS for a while before activating the CUTOUT, in accordance with the runaway stabiliser procedure. The accident crew were also counteracting MCAS for six minutes but do not activate the CUTOUT. It seems that the bad AOA data was probably contributing to a fair amount of confusion, but knowing the previous crew had stabiliser trim issues, and then having those same issues themselves, why didn't they activate the CUTOUT ?
The airline would seem to have significant culpability but is it pretty clear case of pilot error ?
