I think it is useful to discuss any accident, so that we can learn from it and hopefully not have to deal with the same situation ourselves.
I'd like to know what was the likely cause of this fire, whether it was due to gas on a hot engine or turbo, smoking around avgas, electrical faults or whatever, not to judge someone, but to learn from it so I don't make the same mistakes.
If someone avoids being in the same situation due to learning on somewhere like Pprune then at least one good thing might come out of what is clearly a horrible and tragic accident. If someone knows the actual cause of the accident, then withholding that information is not actually doing any good and merely fuels speculation.
