REFLECTOR: Flying Magazine - 2009 Velocity accident

Tue Oct 9 18:59:03 CDT 2012

I don't know.  I doubt any Velocity pilot would suspect flutter at 128
kias, myself.  This was the [LINK:

Vesta prop accident in Houston.  I believe it's much more likely the engine
mount broke because of the vibration, and the weight shifted such that it
went into a deep stall, but I'm not aware of the factory stating any
position on the cause.  I doubt you could check that after the crash
because I suspect the mount would be fractured by the impact if it hadn't
before.

I read the article.  Seemed pretty reasonable.  He simply speculated that a
sharp pitch up response by the pilot may have been enough to throw the main
wing into stall.  Whereas normally the canard would stall and drop the
nose, he suggested that an aggressive pitch up may have provided enough
inertial momentum to pivot the plane into an attitude that would have
resulted in a deep stall.

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.)
