There are a few factors to consider in what causes MD11 crashes, but here's one that links up to 411A's point: MCDonnell taught maximum use of automation in that jet. This was therefore adopted by most carriers in their training programs.
I have flown with 5000 hour MD11 pilots who click off the autopilot at 1000' on final, and never turn off the autothrottles. And get very uncomfortable when I do. This is all a result of the "automation pyramid" that is in everybody's manuals.
If I were king I'd defer all the A/T's and mandate hand-flown approaches in visual conditions.
