PB84, yes of course. But those 'nut attached to the yoke (stick, in my case
) accidents are down to poor decision making by the 'nut'. Perhaps including deciding that flying over an extensive fog bank in a SEP is an OK thing to do?
In other words, if the 'nut' decides it's an OK thing to do, and dies when the engine fails and he can't see the ground to perform a safe forced landing, his death won't have been caused by the engine failure (that possibility is something his decision making should have taken into account). His death will be a direct result of poor decision making. Or unwise risk taking, if you prefer.
So the accident would come under the 'nut attached to the stick / yoke' category, one of the 99%.
