The author got other basic facts wrong. It wasn't Rutan that mounted an EZ
on the back of a truck to investigate deep stall... it was Danny Maier, and
it was a Velocity. Also, the one other fatal deep stall mentioned in the
article was a Velocity where the builder had modified the fuel tanks by
removing the rear wall of the tank and allowing the fuel to go all the way
back to the spar to gain more fuel capacity. That, and the fact that he
flew into a thunderstorm, caused the accident.
Geez....

There are mistruths, he states 3 prior accidents, two landing in the
ocean. He fails to mention one of those was intentional by the
factory, the test pilot elected to stay in the airplane, he had a
parachute, and soft landed in the ocean. That plane was flying the
next day. He states that any canard airplane can be deep stalled at
128K by either aft cg or abrupt pullup! First half truth/Lie is that
it takes a way aft CG, since the redesign you need to be 2-3+ inches
or more aft of aft CG limit and get the airplane in a very odd
attitude, which at 128 knots I think thats probably not doable. That
you can deep stall a V by doing abrupt maneuvers is blatant
speculation and I've never heard of anybody doing it. I've made some
pretty aggressive maneuvers and been in some wild thunderstorm
generated turbulence, by myself(aft CG) and never felt any indication
at all of a deep stall. And the accident plane hit really hard! All
three known deep stall accidents, one intentional, all hit very
softly, and hit flat. This accident turned over, that would not be
characteristic of a deep stall.
He took a few facts, dressed up a few assumptions, sugar coated a few
lies and just made shit up! I think he has a thing against canards
and is playing fast and loose with the facts to paint the V as
inherently dangerous.

You know I've always liked reading Garrison's articles.
I now wonder if most of them are as full of bullshit as
this one? Probably so...

This month's Flying magazine has an article (copy
attached) about a Velocity accident in 2009. The
plane lost a prop blade and this author believes
the pilot mistook the violent shaking to be
flutter, pulled abruptly on the stick, put the
plane into a deep stall, and had no way to use
engine power to break the stall.
I wasn't a Reflector member in 2009 so don't know
any more than what is in the article. Is there
anything to learn from this apart from the obvious?
(Make sure your prop blades stay attached, but
recognize the symptoms if they don't, and fly the
airplane.)
