Yes agree the NTSB but I was referring to the focus of the law.
However now you mention it given the aircraft needed to under go testing following modification other than a personal statement saying it had been done is there any documentation of these hours? What about the pilot who also needs to be current. where is his log book? Then to the alcohol point why was there no blood sample sent for analysis?
Seems its the wild west out there. Can you imagine the fuss if you drilled a "modified" Pitts special into a bunch of people in the UK with the documentation we find here?
I know some people look fondly on this type of sport but come on there is blinkered and then there is this!
