...nobody seems to have mentioned the bloody big hole in the side of the nacelle..
How about engine components which, nanoseconds before, where whizzing around at warp factor snot, escaping when asked to stop in the blink of an eye?
There also appears to be some rather high expectations of an investigation. Analysing CVR and FDR data requires a great deal of expertise - if they were working. And then who will be doing the investigation? I'll suggest that there is not a great deal of experience in this country. Unfortunately, normal procedure in this part of the world is to find the captain and blame him.
However, if you consider these questions:
Was there a DME?
Was the runway lit (are lights installed)?
Was there an official approach?
What were the minima for that approach?
What are the restrictions if the NDB was U/S?
When was the NDB last tested?
What was the weather on the day?
What were the planning minima?
What do the airline's procedures say about operating at Heho?
How much fuel was carried?
What was the technical status of the aircraft?
What was the background of the pilots?
Unless each of these has a reasonably positive answer, this will just be another "Third World Jungle Crash", of which we will see more of as this part of the world gets richer.
Top Tip: Don't fly "Third World" if you want first world safety.
