Just read the initial report. A full CVR transcript and some N1s would complete the picture but it doesn't look pretty as it is.
Can we learn anything from this accident that we don't know already? Don't bust minima, especially on an offset NPA? I think that one was settled some time in the last millennium.
I'm sure there will be compounding factors of fatigue, poor selection, training, supervision, CRM and oversight. Add in authority gradient, cultural differences/mores and there you have it.
If this was a western airline, the authorities would probably be initiating criminal proceedings against the pilots. I presume the insurance company (assuming they were insured) isn't overjoyed either...
