Here's a model report on treating home-builders like grownups.

I sure hope you're being facetious, since it asks that even experimental
aircraft be grounded, even though it contradictorily also states some
aircraft built from that design have already made design changes that make
the cited concerns mute.

The report also references material from the Matronics Zenith e-mail list
and uses it as supporting circumstantial evidence (the core argument is an
entirely circumstantial one of course.) Considering the total lack of
authentication of such e-mail material, it's a bit irresponsible to build
an already questionable circumstantial case on unauthenticated claims.
Also, I've browsed that list and the hysteria and infighting concerning
this issue in that e-mail list almost puts Usenet to shame.

There may indeed be a problem with the 601 design, though the report is
something of a shot-gun affair re causal factors. I guess if they put in
enough issues they can hope to later say "we told you so" no matter the
cause(s) found for the cited accidents.
