In the beta range or feathered? Nah.
Positive or negative torque? Impossible to tell with the facts we have at the moment, but if I was a betting man, I would go for negative as this is the more likely, given the appearances (one of which is the significant sideslip, revealed by the tyre marks, that was evident when the aircraft made first contact with the roof).
Really so the figures given between 2000 down to 1586 Np. Pt6-42 is a free turbine engine. And even at a Np of 1586 the engine would be driving the prop. If you understand the engine and how it works and given the facts that are already proven and documented you can say that the prop was not free spining. Slide sliping across the roof of tne main wheel can caused by multiple reasons.
