I don't know anymore where I read the studies (ASF ?)
that concluded that single engine turbines where
safer than multi engine piston's and multi engine turbine's.
The rule of thumb I remembered is that on engine failure the second engine only will get you to the accident and in cruise it will add to your fual and maintanence bill so there is no real argument against commercial night IFR ops in single engine turbines.
I think it's a great plane and if you are ever around and need a FO , anytime
