Rustle, AFAIR we flew to Jersey in CAVOK, so weren't able to test proclivity to crash in icing. There have been a number of Partenavia + ice crashes, I am sure from a variety of causes, but the air intakes is one most cited. Do late models have automatic alternate air?
LowNSlow, the push-me-pull-you design brings it's own dangers, because it is very difficult to recognise a rear engine failure, which has led people to stall.
