It never happened on the ground, nor in the climb. It looks to have happened as the pilot turns the aircraft to transition to forward flight.
Is there any significance to be drawn from the observation that the failure appeared to happen at the first point that the pilot commanded a yaw to the right (i.e. counter the MR rotation) as opposed to the slight yaw to the left observed (and explained earlier) during the climb?
