The Ethiopians say that the crew followed the procedure for runaway trim/MCAS, but from their own report, that isn't clear. It shows that they identified the trim problem, the first officer indicated they should disable the electric trim and the captain agreed. It was turned off and while MCAS tried to move the nose down again shortly after that, it had no effect. After that they continue to fight with the plane, the captain asks the co-pilot if trim is working and he says no and asks if he should use manual. (that's bizarre, as all there is at that point is manual trim, so what did they think they were doing after turning off the electric?) A few secs later the co-pilot says that it's not working, but no explanation of what he meant by that. Sometime after that someone put the electric trim back on and 5 secs later MCAS shoved the nose down again, 30 secs later, it crashed.
Not answered is what the co-pilot meant by the trim wasn't working when he tried manual trim? Was he trying to move the trim wheel and it would not move? Or was he confused and really trying to use the buttons? And who turned the electric back on, without apparently any discussion? You would think these aircraft would have video recording too by now. That would help show who was doing what. One major mistake here is that one of the two pilots apparently turned the electric trim back on without discussion or informing the other pilot.
Also in that report are prior trouble reports logged, there are several prior incidents where pilots reported the plane rolling unexpectedly, strange altitude and other indicators in the cockpit that appeared briefly, etc. Another thing that would not seem to make sense is that if it's just an AOA/MCAS thing, why did the pilots airspeed differ significantly from the co-pilots for much of the flight? Leading one to wonder if the MCAS thing is all that's wrong here. the plane.
