On practical terms the final report will be of limited added benefit. What is known so far has already painted a complete enough picture to see what happened, the crew crashed a functional aircraft on their own.
The particular and perplexing sequence is something a crime-story novelist could have come up without much creativity at all, simply by combining elements from historical accidents. Probably even from the last decade, the age of information.
Besides, researching the hows and whys is not the reason for the investigation in the first place. Going back to the definitions, the sole purpose is preventing a re-occurrence by defining and implementing mitigation measures (which might also come in simple terms of re-focusing on safety targets already known before).
The pertinent questions, after the full report is out, would be (random order):
1) What could the ATC possibly do to break-up an identical chain of events the next time?
2) What could the aircraft / engine manufacturers possibly do to break-up an identical chain of events the next time?
3) What could the first officer possibly do to break-up an identical chain of events the next time?
4) What could the captain possibly do to break-up an identical chain of events the next time?
5) What could the airline operations managers possibly do to break-up an identical chain of events the next time?
6) What could the airline S&Q managers possibly do to break-up an identical chain of events the next time?
7) What could the CAA possibly do to break-up an identical chain of events the next time?
My suggestion is the understanding today is on a sufficient level to get moving on each of the separate points above. On top of which: The existence of an SMS system utilizing FDM / FOQA elements, long mandatory for airlines such as PIA themselves, would had prevented this completely unnecessary loss of life.
