Not arguing in favour, but I think I know where the inference to the mast bumping originates. In the investigation documents (I am not allowed to post urls yet, so the long way), from the flightsafety page you jump to the NTSB Docket, there you can access the '
Helicopter Airframe Examination Report'.
On page 12 there is clear evidence that the stops made contact with the mast, though importantly the investigators offered no speculation as to when the contact was made, ie was it the cause or result of the rotor-system through upper deck departing.
