Default T-6 accident

doubt it or he would have turned into the ground pretty quickish. just
not enough top rudder would be my guess.


I looked at the rudder position as he completed the first 90 degrees of the
roll, and it looked like the rudder was completely neutral. Did you see
that, too?


Rudder deflection isn't as much as one might imagine during a roll. Most
pilots are used to looking at their own rudder deflection on the ground
as they check the rudder throw each way. In a roll, with dynamic
pressure on the rudder, it actually deflects very little to produce the
desired effect.
The flatness of his rotation off his roll axis between knife edge and
impact would seem to indicate a bottom rudder producing yaw. If it was
back pressure applied too early, assuming he had kept in the rolling
aileron, as he continued to roll into knife edge and the nose came down,
the back pressure would produce turn that should result in the impact
being at the left wingtip rather than the flat rotation he seemed to
experience prior to impact.
