But this scenario maybe coul'd fit when to presume that pilot counteracted with full column pull back.
On the other hand, to move stabilizer to full down position (f.e. with elec. stab trim) you need time - it's 30 maybe 40 wheel turns from nose up position. And on the presented ADS-B data we can see rather fast pitch drop (from +10 to -30 in 7 sec.)
So something still is very unclear in this case

I believe the full aft yoke was totally ineffective because the tailplane had stalled due to ice accumulation.
My reasoning is due to two simple facts:
1) The aircraft flew in icing conditions for an unusually long period of time.
2) The aircraft behaved as if the tail was stalled.
Sometimes the simplest answer is the correct one.
