also give a thought that it is rare for a detailed discussion or analysis to be published where operational errors may have contributed to the accident chain.
After all the most important things to the rest of us are product updates , or manual updates. These are almost always put forth even without the benefit of a long drawn out report process. Things that are unique to an internal process (regulatory compliance, operator training sylabus, etc. etc.) rarely get published or at least take a much longer time to appear in the public domain.
From my view, most accident investigations are well served to get the right words out quickly to prevent future accidents if you read between the lines of the first months information following an accident.
Now if it's blame or finger ponting that you are looking for, don't hold your breath.
