As I said in a previous post, if you want to make good use of statistics you have to be prepared to do some work.
The statisics you refer to from NASA do not include the following, but when you fly your aeroplane they are surely included:
Human induced failures
Failure due to mechanics poor skills/procedures
Failure due to improper parts.
There are many other exclusions in the data as specified on page 11 of the document.
I am quite happy for you to make your own risk appraisal, as you are for me. The problem is others may make a risk analysis of their own based on this thread.
