I saw this breakdown on p.w, all apparently due to ice changing the flight characteristics and weight balance of the turboprop plane to the point where stalls and flat spirals became difficult if impossible to pull out of without tearing the airframe apart.
Ignoring the weather warnings seems to have been the key mistake here, but thats not to say that sabotage and assassinations were not motivations in play also.
