No, but why else would they have raised the flaps and the gear? We can speculate all we like. Just personally If I had discussed icing and entered a stall I may very well have reacted exactly the same way. It would be very difficult without any buffeting from an impending tail stall to segregate which stall in fact was happening.
You mean besides the fact that:
a. The airspeed was WAY down into the red tape
b. The shaker was going off
c. The pusher was going off
d. NONE OF THOSE HAPPEN IN A TAIL STALL!!
The way the tail's airfoil is shaped, it will only stall at airspeeds WELL BELOW where the wing stalls. Therefore, the only way a tail stall can happen BEFORE the wing stalls is if the tail accretes ice, prematurely separating airflow and stalling the tail.
IF that happens, the tail will stall at airspeeds well ABOVE the shaker, nudger, or pusher - that's why the danger exists - there's NO indication of it except for a "mushing out of the controls", lightening of up-pitch control column forces, and finally an UPWARD pitch movement of the aircraft.
If you're in the red tape, the shaker actuates, or the pusher actuates, it's not a tail stall, it's a wing stall. Basic icing training should have covered that simple fact. If that's what he was thinking, then he wasn't paying attention in the icing class.
It also appears that SHE was the one who raised the flaps. He never commanded them, and the CVR records her as saying "I got the flaps up, you want the gear?" If I was a betting man, I'd say she didn't see the unusual attitude, but DID see the airspeed increasing and yanked the flaps, thinking they were recovering. Bad news is that they were still well into the tape, wasn't NEAR time yet, the unusual attitude notwithstanding.
We'll never know what either of them was thinking, just have to learn what lessons we can and apply them going forward.
