Not to overstate the obvious there are so
many more piston IVs flying that the normalized accident rate of turbines is so
much higher, and that piston IVs have been flying for so many more years.

As of 8 June 2006 there were 4 IVP
turbine accidents reported/ 25 IV accidents and 6 straight IV accidents. I know
because I keep a set of books on this and brief the Lancair group every year at
OSH on this.
