‘zero# redundancy by the discontinuous rotor mast and by an extensive ‘de-axation / outlining’ between bevel gear and upper ‘rotor shaft bearing’ in the conical housing?
AW009, I looked at the plans and I do not understand where you see a misalignment ?
As for the rotor mast, I do not see what you mean by "discontinuous" ?
(I am not a neophyte but you may know more than I do)
