For investigated landing overrun incidents to the A320, we have seen the following leading causal phenomena:
* Technical fault (Ibiza)
* Mod Confusion (Bilbao)
* Pilot-handling confusion (Phoenix)
* Overly-fast touchdown (Warsaw)
* Unknown (to me) + pilot handling (Bacolod)
What we *don't* know yet about the Congonhas accident:
* Touchdown speed (guessed from video: 130 kts +- 10)
* Touchdown point
* Whether reverse was used (guessed from video: on port)
* What the starboard engine did
* Whether airbrakes (5+5 spoilers) activated
* What braking action was selected (guessed: manual)
* Whether antiskid was activated
Given that we don't even these basic parameters, BOAC's suggestion that we'll just have to wait for the FDR readout seems right on the mark. Until we know these, we can't even begin to judge whether the accident has any causally relevant similarities to any of the other overrun incidents above.
