That is correct about the line.

The Grob 103 Twin II Repair Instructions Manual I have, dated
September 1981, says the lower surface of the aileron is 2 layers
92125 diagonal. No core material. All the rest of what JJ said, I
would say is good and true.

Does this mark run the full span of the aileron, or at roughly 45
degrees to the aileron? You said it goes from the trailing interior
edge to leading outside edge of the aileron. It could simply be a
crack in the finish at the edge of an overlap joint of the outer layer
of glass structure.
