Wsherif1, I appreciate you're rewording, but my question still stands. How could these .3G and .4G forces from a wingtip vortex against the rudder, cause complete failure of all the rudder PCA attachments?
I've tried to follow this accident, and I've read nothing from the NTSB (or other sources) indicating that the failure of the PCA attachments to the rudder, was a precipitating cause of the accident. It it were, the NTSB has been focusing on the vertical fin attachment lugs and pilot use of the rudder, in vain.
