The Transasia over run by an A320 was also on a wet runway and they also had one thrust reverser inoperative. The spoilers also did not activate due to pilot error on landing. The charts showed that with one thrust reverser inoperative and spoilers not deployed, the plane couldnt stop even on the 9000 plus foot runway. What chance did our people in Sao Paulo have to stop on a runway that is much much shorter?
TAm's A320 had one reverser inoperative and the spoilers seem not to have been deployed either. IT simply could not have stopped in time then, it would appear.

I havent read the report in its entirety . Perhaps some A320 drivers can gain more insight from the Taipei over run as applicable to the Congonhas accident?
