I just looked through the manual of my Sundancer, and I cannot remember my wing looking like that. Almost looks like the wood was stripped out by over tightening the screw. Looks like that is how the guy tried to fix it. On my Sundancer the wing was solid in that area, with a hole drilled where you were to screw in that bolt. Yours looks like the sheeting has been cut away. According to the manual, the top wing incedence should be 0 degrees, and my wing tips are not pulled down at the tips. Hope this helps.
