A good friend has an Acro Sport 1 that has an interesting problem we are trying to figure out. Neither of us has plans to refer to.
His lower wings, both sides, have a fabric problem chord wise on the leading edge. I have included pictures, as my description will be lacking. Please ignore the mismatched paint and patch... The first picture is the leading edge looking aft, right wing. Second is the same view, left wing.
What could cause this and is it something to worry about structurally?
