I have a feeling that this accident will become more puzzling once FDR available.
The plane left the normal law, that's clear.
Aircraft entered the stall and then probably a spiral dive that PF or something managed to reduce it to a developed stall.
We know that FDR and CVR recordings stopped moments before belly splash. Perhaps, THS was separated along with APU and recorders. Considering the relatively low damage of the wreckage, it is possible that THS broke at low speed, ie below the speed of maneuvering. Is this a case of induced oscillations that lead to extremely high aerodynamic loads on THS? Was there a battle between FAC trimming NU for low g factor versus PF trimming manually for speed recovery. Is this a cocktail of crashes of the big brother, AA + AF?
