On post #2469, Causality
One factor that is definitively causal and that I keep missing in the shortlists of causal factors is the fact that all accident approaches were carried out with AutoThrust engaged untill touchdown.
It is relatively easy to understand that a hand makes a mistake at one critical moment of action (just half a second action time) when it has been sitting lame and passive for many minutes and if in the brain there are several ideas floating around about the action to be undertaken (do something not completely equal to the thrust levers because, ....).
An approach using manual thrust could not result in the same accident sequence, because, even if a thrust lever was left at approach TLA, that would only be 1.05 EPR and would not increase during the flare without active involvement of the pilot flying.
It is highly unlikely that all of a sudden, during the flare, one T/L would be left behind (forward, to be correct) when, for many minutes prior to that, they were actively moved together.
For the statistic sample, that would cut out a lot of landings - I estimate that 30 to 50 % of pilots always use manual thrust when they fly a manual approach.
