Just read a wee update on bbc news.
Apparently both engines flamed out, eventhough 75kg of fuel on board. No problem with fuel pumps or lines/filter etc.
Don't know if anyone has prior knowledge about this sort of thing.

Any idea why the rotors would not autorotate when the engine and gearbox show no fault? Pitch angle issue with the blades?

No reason that I have ever known of. Proviso is that the collective lever needs pushing to the floor immediately regardless of any other actions taken, as once the rotors decay there is no way of getting the revs back again. If he thought about it or was taken completely by surprise, then that could explain it. However that does not seem likely from the last report that I read in February which stated that one engine flamed out followed shortly by the other, so he should have put a Mayday out straight away and prepared for the other engine to fail and set up for an autorotation.
At altitude that then gives you time to look for the best and safest spot to put down on, preferably into wind. I don't know if they established his height, but I suspect that he was at low level and maybe even trying to stay visual under a cloud base. In that case the most he could have done was enter auto and descended straight ahead at something like 2,000ft/min. If that had made the pub his landing spot he could at least have landed on top of it at zero speed both forward and vertically if he had judged it correctly and been in practice.
Which brings us back to why were the rotors intact and not turning at all, any rotation would have damaged the blades. The transmission was turning freely and disconnected from the engine drive, and it is this that has led to no further progress on what actually happened.
