Mr. P51: First, let me say there is only one rudder on the A300/A310 series.

Second, I do not have any 'data' in my possession, but have witnessed the FDR raw traces, which by the way, are not exactly raw. The A300/310 series came equipped at the time of AA's (among other airlines) purchase of them, with one of the worst performing FDR's on the market. These units were soon de-certified for use in later build aircraft. Not an Airbus issue, but worth mentioning.

The key issue the NTSB publicly admitted, was the problematic 'filtering' of raw data before it ever got to the FDR recording media. This alone, by the NTSB's own analysis, precluded them from ever really knowing exactly where in its travel range that aircraft's rudder was and when.

They were unable to sanely explain how in the space of under 8 seconds there could have been four "commanded" rudder reversals. Yet, they managed to ultimately and unfairly place the blame solely on the FO's dead lap. It boggles the mind.
