AW009....I enjoyed the Video's you linked.
With the latest news being discussed extant....you wish to expend some additional effort in discounting the possible involvement of the Epicyclic Module as in the previous tragedy?
It is still early in the investigation and lots of questions remain and more work needs to be done but even as an idle spectator to discussion One simply must think Gearboxes just do not fail that often anymore and for two to have gross similarities resulting in a loss of the Main Rotors as a group.....One must wonder why!
I am quietly waiting to hear how all this turns out but evidence keeps turning up that brings us back to a possible cause a lot of folks just do not want to confront for any number of reasons.
