Ignition Overide,
Your comment,
"my point therefore was to solicit comments about the alleged over-sensitive characteristics of the A-300's rudder system."
Whether the rudder was over-sensitive or not has little to do with the accident! The large, total flat plate surface area of the 27' tall, vertical stabilizer and the rudder combined, when struck broadside by the 0.8 G force of the rotating vortices of the B 747's wake, induced an instantaneous left YAW maneuver. The resultant, tremendous inertia force sheared off both of the massive engines from their support structure, and tossed the right engine to the left of the aircraft's track and the left engine to the right of the track, as indicated in the engine ground location graphic! This same left YAW motion induced the abrupt, left "Dutch Roll" into the ground!
