AF Accident rate
Two points:
1. Arbitrary start date, 1988, moves Habsheim crash into the 1988-2009 period.
2. Wikipedia page says AF had 3 fatal hull losses in 1968-1969
... so you could say: AF had 4 accidents in 1968-1989 period and 6 in the 1990-2009 period. And that this doesn't take into account the increasing size of the airline over the period.
The point is: accidents are rare enough that they may or may not tell you anything about whether safety culture of AF has improved or decayed.
I don't have an axe to grind, and I don't know anything about AF (only flown with them a few times). But for any western airline it's nearly impossible to make meaningful statements about safety culture using hull loss statistics.
There's a more technical prob/stats explanation which I won't burden you with...
