Tinstaafi, that is intriguing, I know accident stats are always skewed as you only tend to hear the accidents with fatal outcomes reported (ie: Engine faliures where they end up landing safely rarely get much notice in hte aviation press) , but everytime I read a king air incident there seems to be a reasonable number where the aircraft ends up rolled past 90 degrees with the obvious negative outcome. However it seems to tie up with the effect you mentioned there. I believe that there is no surprise that the Autralian Flying Doctor Service opted for PC12s rather than an equivalent sized twin turbo prop; as I believe the stats show a far better safety record with a SET than light twin turbines.
