fdr...the "Tail"
"The FDR showed no evidence of a change in the structure or aerodynamics or response of the aircraft to control positions."
Check the Rudder traces, and re-read CVR. Especially make note of Hdg, altitude, power and control positions at the moment Autopilot quit....review "jet upset"... add in the "zoom climb"; would be interested in your remarks...
