Wow, This is the busiest this list has been in a long time, if ever. While=

we all knock ourselves out with these issues consider the following:

engine block. Less for the rotary, but a fraction of a small percent is=20
still a small percent.
2) Less than 30% of all accidents are caused by loss of engine power for an=

reason. Obviously more for any auto conversion or unique installation, but =

would guess that increase is not exorbitant. This figure is mostly due to=

fuel starvation for one reason or another. In order of incidence: poor fuel=

planning, carb ice, vapor lock
3) That leaves more than 70% of all GA aircraft accidents due to: pilot los=

other. These figures are not likely to change much regardless of engine=20

 Have you touched your airplane today? :-)
