The real Q is would an FAA CPL/IR/CFII, in a Jetprop with all the gear, be doing that?
With the technical knowledge and equipment available in this case, this accident would have been easily avoidable, either by going to Vienna (5 minutes' flying time away) or, if you really must, by flying an illegal but highly accurate and safe DIY instrument approach to LOAV.
But who knows the answer. I know what I would have done.
