What would explain the need for constant roll left, to maintain SL?
damage? AIR ? cg? Likewise NU? cg? ICE? All we see is the response, not the stimulus.
Whilst I can visualize the stall I cannot understand the aileron inputs.
The possible causes are updraft/turbulence - very unlikely at altitude in my experience.
Dutch roll - wrong duration of control input.
Asymmetric ice accretion ??? doubt it but..
flight control fault - side stick - computer or hydraulics or roll damper.
If the published data is correct and the aircraft wasn't in a stalled condition then 30 secs of full sidestick in a non protected aircaft should see it upside down.
My money is there is something missing which confused the pilots even more.....
Forgive my ignorance if alternate law will stop this happening - I didn't fly the bus although I had the chance.
