I can't help feeling that the only people who will gain out of all this is the lawyers
There is much speculation and that can only be a good thing in my opinion. The more we as pilots look at the scenario and the more we use our imaginations to look at what we might have done, hopefully we might learn from this terrible disaster.
Whether or not the crew did the right thing doesn't matter. We may never know what lead them to make the decisions they made, correctly or otherwise. Nor can we sit and type, claiming we would have done differently - we simply don't know at this stage what really happened. For example, changes in speed might be down to someone mixing IAS/TAS/GS or indeed changes in wind speed.
Lets hope that the 92, great as it is already, becomes even safer than it is. And if replacing the bolts really reduces the chances of the gearbox ever emptying itself of oil/loosing pressure to negligable (from the perspective of the pilot's not accountant's/lawyer's), then who needs 30 mins of dry running time. All everyone wants is a helicopter that gets us back safe, everytime.
