Con-pilot,
With all due respect the numbers don't support your claim about being dangerous, in recent years the BE-200 has had more problems than the MU-2. Like any airplane, maintenance and training play a big role, properly maintained it is a very low cost turbo prop to operate (compared to the BE-200 and SWIII), the NTS system is not an MU-2 system it is a Garrett / Air Reasearch system, the P&W counter part has the Auto-Feather system, equally important.
