> In the second incident, the crew restored trim 25 times and never thought to turn off the trim system, over a period of 11 minutes. This is plenty of time to remember what the runaway trim cutoff switch is for. There's no excuse here. > ... > The stab trim switch is a memory item, meaning it is supposed to be memorized by the crew. It's their job to remember it. The runaway trim memory item was written in a way that was inconsistent with how MCAS runaway behaved. The steps were: > Firmly hold control column. Disengage autopilot if engaged. Disengage autothrottle if engaged. Use the control column and thrust levers to control airplane pitch attitude and airspeed. Use main electric stabilizer trim to reduce control column forces. > If the runaway stops after autopilot is disengaged, do not re-engage autopilot or autothrottle; end of procedure. > If the runaway continues after autopilot is disengaged, place both STAB TRIM cutout switches to CUTOUT. > If the runaway continues, grasp and hold stabilizer trim wheel. Historic runaway stab was generally consistant running, not a cycle like MCAS, so following the check list, you turn off the auto pilot, trim stops, you consider you completed the checklist. When it fires off again, it's not completely unreasonable to believe that it's not a runaway trim, as you completed the checklist as instructed. As for the third incident, the Boeing Emergency Airworthiness directive specifically said that this issue only happened under manual control. The crew kept engaging the autopilot and when it continued to happen on the autopilot, it's not unreasonable for them to believe it wasn't the same issue per the Boeing Emergency Airworthiness directive. Could they have done better? sure. Could they have saved the aircraft if they followed a different train of thought? yes. Was their train of thought unreasonable? According to the investigation, no, it was not. To many many other people who study this stuff, no one that I'm aware of places any blame on the crew and it feels wrong to continue to shit on their skills when from all indications, they did follow procedures as written and it wasn't enough.
