I've got a few thousand hours in the beast.  

The only reason it would spin uncontrollably would be either a control malfunction our hyd problem.  

It could easily hover single engine, but if it did have a dual engine failure, which would only be due to bad gas, it still doesn't explain the spin, unless the pilot was so fixated inside he did recognize the spin until it was too late.  That would also explain not reducing the thrust in time also.
