One other thing noted to me was since this a had a free turbine the prop blades would stop on impact and not be driven to curl the blades on the prop as in a direct drive engine like a piston. It very well could be that these blades as pictured were not feathered, rather that is the pitch they were in and they did not display rotational damage due to being a free spooling turbine. That seems likely as the time to impact was so short from controlled flight and feathering the prop wouldn't be an expected reaction to a OCF.[/QUOTE]
If memory serves UJC although not direct drive the few crashes I have seen still resulted in prop distortion. Tip speed would be reasonably high. I will let the people that have more recent experience comment further.
