PX (and many other airlines worldwide) have had similar close to stall incidents. How do I know..... I was involved in a serious incident many years ago when I was at PX, and yes icing was involved and myself and the other pilot miss handled the situation. Why, I put it down to lack of experience flying in icing conditions and the lack of training/awareness provided by the company. It can happen to anyone if the cheese holes line up.
