AA 587 was a classic example of a huge world supplier of aircraft (Airbus) being protected by the investigative agency (NTSB) to cover up Airbus's gross negligence.
The rudder limiter on the A300-600 was a monster very few pilots knew about. But to blame Airbus would have put that company in serious jeopardy. So, what to do?
Find a convenient vehicle to channel the blame and protect Airbus at all costs. That vehicle was AAMP and the pilots' rudder inputs.
Case closed, "pilot error." What a crock.
AA 587 had **NOTHING** to do with AAMP and **EVERYTHING** to do with the poor design and lack of info on the A300-600 rudder limiter. F/O Sten Molin had no absolutely no idea the rudder was deflecting fully when he made very small inputs to help arrest the high roll rates that full aileron inputs only were not arresting. Every one of us would have done the same thing. Full aileron not stopping the roll rate? Of course we add some rudder. But we don't wanna put Airbus out of business now, do we?
