I think the NTSB said the loss of control happened after Flaps 15. I'd be worried like you with those large CP changes with a tail that by all accounts could use more surface area.
Sounds like the loss of control happened just after the final flaps setting. If so, the q400 quite aggressively pitches during the transition from 15 to 35 degrees...especially with the auto on. Also, the elevator buffets like crazy while configured at flaps 35. Neither of those scenarios makes me feel good when flying an inverted elevator in icing with the autopilot on.
Clue please: What' an inverted elevator???
I really doubt Bombardier engineers eyeball the proper size of a control surface, do you? I've always thought that the A340-600 vertical stab doesn't look proportional to the fuselage, should I look into launching an investigation of Airbus?
Do you regional guys practice the tail icing recovery maneuver in training? I've had it on occasion in various corporate training. It's worth going through as it's not something you would naturally do in that circumstance.
