Tom, you chooses the 10% or so of accidents which had enough data to come to a conclusion. Even then I would question most NTSB reports until I talked to the locals who knew the pilots involved and can confirm the accuracy of the report. I personally know of quiet a few fatal accidents which can not be classified as poor airmanship. At the same time I am aware of many poor airmanship which did not result in fatal accidents.
I guess what I am trying to say here is don’t fall into the “this would never happen to me since I am a good pilot” category. I know I don’t kid myself that any of these accidents couldn’t happen to me.
