"The report will likely tell you absolutely nothing about what initiated the accident"
You may be right, but from the photo's that have emerged and been made public, the rear empannage was relatively unscathed. The position of the elevator trim for take off will likely be obvious, if it was where I suspect it was, then the likely sequence of events will become known with some certainty.
What iniated the accident happened long before this occurence. That has been confirmed by the haste that the AD was issued.
