If there had been a technical/mechanical problem then Airbus/TAM/CIAA would have at least done some checks on other Airbusses, issued technical recommendations and bulletins, instead they have revised the MEL and given advise to all Airbus pilots in the world to make sure to close the TL on landing (what a useless recommendation!). I'm pretty sure that in the investigation, the first they pulled after the recorders was the power quadrant.
I think we can easily rule out any other reason than the obvious one. The problem is that this thread has become so long, that the latest users don't know anymore what the first ones wrote, hence repeat arguments that have been falsified longtime ago. I think we can safely argue that the pilots left the TL in CLB detent, for yet unknown reason. This would cause an overrun in any aircraft, also in a mechanical Boeing. And if they did it intentionally (which most of us believe) there is also no moving TL of any help.
Back to the facts please...
