A witness reported the pilot moved the control stick
in the cockpit and observed movement of the flight controls, but he

I had the opportunity to discuss this in detail with Tom Knauff and the owner
of the Cirrus on which the replicated the failure mode.

The flight control would move correspondingly with the stick movement because
the weight of the elevator kept the C-hook and the elevator in contact. IF
either one of the team (PIC at cockpit or assistant at control surface) had
done a proper PCC, it would have been evident either while applying resisting
pressure while moving the stick in full deflection or from doing a jiggle test.

The assistant in this case is a licensed glider pilot.

I was the field manager that day, and hope never to experience something like
this again. To this day, I still see most people there doing a simple prayer
hand PCC. Go figure.
