Thank you for the excellent description of the systems. I think it will be interesting to see if a possible engine failure was involved here or not, though regardless of that, I have learnt something new today
What I was trying to work out was whether the prop could feather to the position in the photograph on its own (allowing the possibility of failure very shortly before the accident), or whether it could only have ended up there after the drills had been carried out (suggesting it may have happened earlier on in the approach or previous hold).
Obviously this is all total guesswork on my part (and also assuming that the position of the prop is not just a result of the accident itself), but just a thought that had occurred to me...
