Another view of this "charred" looking (to me - who knows nothing) detachment area of the tail fin - left forward side. Explanations for that appearance? (the charred looking part) Any ideas?

The material that the tail fin was made of is a carbon fiber composite. The dark material is probably just exposed carbon fibers, althoug I agree parts of it look charred. Of course friction from a part working loose could do that too, I suppose, but I would hope such looseness would have been noticed earlier.
