Yes, BUT don't let that warning read with too much meaning, either.

there are many, many homebuilts that far exceed the FAA
standards. Some of the quality in homebuilts make certified aircraft look
like erector set airplanes, in comparison. g


Of course. As I pointed out to the Bradley Aerospace
(Bradley Aerobat) company rep, 6061 T6 has 95% of
the yield strength of 2024 T3, and better corrosion
resistance so that you can make back some of that
minor weight penalty by using less paint.

He keeps harping on how 6061 is not "aircraft aluminum".
So I asked him which standards organization sets the
standards for "aircraft aluminum". His response to that
was to delete my earlier article comparing 2024 to 6061.

As far as I can tell, "aircraft aluminum" is marketing hype
used to promote non-aviation products to a naive public.

As such, the term fits right in with Bradley Aerospace's
approach to marketing.
