Proping Question

Although I agree with the dangers of accidental engine starts, what I
would like to know if there really have been any cases of inadvertant
engines starts when the prop is turned half a rotation with the
mixture in cut-off even if the magnetos were on. All the cases I am
aware of are related to hand-propping, which is not the same as
turning the prop to reposition the blades.- Hide quoted text -

Yes, engines have hurt people. You can kill it with the idle
mixture cutoff, but if someone has fooled with the primer (or boost
pump on an injected system), fuel will be present and any spark could
set it off. An example is a failed start attempt, due either to a
flooded engine or cold weather. That prop will be dangerous with the
mags on. Turning it forward is insane.
