In his debate about the suspension bars, the eye witness described an oscillation before the loud banging sounds (3 or 4), then parts coming off and then the rotorhead departing. What is the significance of this? Well, forces many times more than the 2.5 g (for example) that the helicopter was designed to withstand. If these oscillations were the result of a support bar or pin snapping as the possible theory would suggest, then the remaining two bars are now dealing with angular forces they are not designed for and not capable of coping with, including the mounts to the airframe. The bars are able to carry the load if the load acts in the direction of the bars and the mounts, but if you put a twisting force on them (to the magnitude of multiples of 9t) then I will guess they will fail.
In an instant.
