Hinge 5 is the lower hinge of
the largest piece of the rudder. The hinge cover (image 7) exhibits
the same port side damage seen in the actuator hinges. The damage
to the hinge (image 8) itself and the attachment point seem to
imply a top down tearing (figure 6), with a port twisting. I
think it failed in a downward motion and is pulled through the
port side of the hinge cover as the rudder section pivots backwards.
A top down tearing would seem possible when viewed in light of the damage to the trailing edge near the base of the rudder (figure 7 & image 9).
Ultimately this large piece of the rudder broke inline with the area above hinge 4, the top most actuator hinge. As this piece separated it weakened the trailing edge of the lower portion of the rudder and exposed the widest, most hollow part of the rudder to the slipstream.
