Well, weight and balance, removal of 2 out of 4 props, just the general
attitude towards compliance. Fudging an hour or two to get to OSH is one
thing. If he'd had a lot of high performance time, some shortcuts might not
raise as many questions, but 200 hours in a Cherokee?  I thought the battery
was determined to be the cause of the accident.  I know it's not spelled out
here, perhaps I heard/read about it somewhere else. Didn't John Denver meet
a similar fate?  Something about using vise grips on a fuel selector valve?

This guy overloaded himself, and sometimes "not following procedure" is the
cause of an accident.

BTW, Good decision Chris M. on figuring your engine problem out after the
move to NC. BW
