Howdy,
Relative to my post above, the (electric) motor actuator had to have endured highly stressed loading. Heat could easily have compromised the action... I don’t know about “useless”, but switching could have been highly degraded. At the final one way increase in Nose Down Trim, the HS could have been frozen, but the action shows a steady increase in leading edge movement UP, not consistent with duff motor?
