I have an aeronautical engineer friend retired from McDonnell
Douglas who once was in charge of the Harrier project for the U.S.
team. I respect his opinion which is that pull type, "pop" rivets are
only used on aircraft where a bucked rivet could not possibly be used
or on non-critical, low stress applications.

It is my understanding that the bucked rivet, which has been
used over the years in aluminum aircraft, is stronger than the pull-
type pop rivet. In consideration of the Zenith Aircraft 601 and 701,
how is it that they are using a Textron Brand pull-type rivet? Has
there been some breakthrough in material or design in theses Textron
pop rivets making them comparable to the old style "bucked" rivets?

Thanks,
Andrew

The Zenith line of experimental aircraft are designed around the Avex
pulled rivets. Gigs statement about 4=3=1 is a good way to look at the
fastener concept. So far my Zenith 801 with the V-8 Ford in it has
shown no signs of failing at any joint. Yet. G I can tell ya it has
14,210 pulled rivets in it. :-)
