Its coming from the crew members that were onboard, flight control malfunction, caused by what is unknown till NTSB crawls over the HYDs but completely uncommanded right roll that got the aircraft inverted twice before pilot could fight it back.  Collective flat pitch to get on the ground as fast as possible, overspeed of rotor system which at that point would be the least of my concerns.  What happened in the next 20-30 seconds till the landing and how much control he had vs hyds trying to pull the aircraft on its side or who knows what is the unknown.  Thankfully aircraft didnt burn, everyone walked away, pilot got some serious injuries but alive.  Expecting some AD/EASB's in the coming weeks as they take the HYD pack apart and see what happened.
