Lonewolf, caution noted; there was no intent to chase solutions for this event, which may only have limited value as accidents are rarely repeated in every detail.
We can wait until the 'facts' are available, but all that might do is confirm what happened during this accident, and provide little guidance as to avoiding the next one.
However, from the discussions in this forum there appears to be strong evidence for safety concerns about the AT system.
The greater the level of safety in aviation the more the need to pay attention to 'small' issues.
