Hey Lebl,
Would you agree that if you can see any portion of the bolt on the side opposite the nut, without that side of the hub attached that regardless of whether that part of the hub is still attached to the helicopter or not that for the bolt to escape it it means the end must have come off. or the hub split at the bolt hole.
Unless Houdini was up there with a hacksaw unbeknown to anyone.
I agree, we would all like to hear some positive answers and pronto, they have had the bolt and hub now for more than long enough to crank up an electron microscope and peer at it.
Totally unfair to be sitting on that sort of evidence.
