Factual report?
IIRC the investigation data was based on rudder position and there was some doubt as to whether it was pilot error and not a software problem. Having put out a May day with a similar, albeit analogue,problem on a heavy where we had zero feedback through the pedals and knowing several instances where systems do not always do what it says on the box I would hesitate to believe the official report. I would add that I have yet to meet a pilot,even glider pilot who leads with rudder, especially relevant as some of the gliders I have instructed on needed full rudder to compensate aileron drag with 1/3 stick displacement.
