I get the impression that you don't like Airbus products - your last line, combined with your focus on the fatalities in accidents involving Airbus aircraft is quite revealing. Why is this? A similar superficial analysis of accidents involving Boeing, Lockheed, McDonnell-Douglas or BAe aircraft would probably show comparable fatality-per-accident rates.
Yak Yak, as far as I am aware, there are no Airbus accidents attributable to computer failure. There are, however, a number that are attributable to airlines' failure to train crew adequately in the handling of those computers.
