Also, the accident stats show running out/unable to use fuel causes a substantial fraction of engine failures in both singles and twins. Twins also seem to come to grief more often than comparable singles (i.e. BE58 vs BE 36) due to system failures. However, if my mission profile was night ops over water, I would still go for the piston twin vs piston single. However, the stats I have seen suggest the in-flight shutdown rate for turbine singles is lower than the double engine shutdown rate for piston twins - so the piston twin might be an illusory comfort blanket vs. a turbine single.
All of which is a bit odd in a thread about a PC12 going down where we have no indication at all of an engine failure.
