The requirement of 51% amateur construction appears to ensure that a kit built aircraft is more unsafe, which doesn't make sense to me. Why is the FAA rabidly insistent on it? What possible logic is it based upon that a pro mechanic isn't better than Joe Schmo with his Walmart tool box? I have noodled it tenaciously & followed the $$$...Might it be the certificated aircraft manufacturers have lobbied it into some kind of rationale to limit competition?

p.s., my apologies to Mr Schmo
