Default Wing structure question.

I have a replacement composite wing for one of my jets. I happened to notice that there was a decent amount of movement along the whole top of the wing. When I borrowed a camera and scoped it, I can see about a 1/16 to a 1/8th inches gap between the lengthwise vertical wing structure and the skin. There is also asimilar gap between the wing ribs and the top skin. Even a couple in the front. Almost like the supports were a bit too short or not enough glue was used. This includes the landing gear area also and some point at the leading edge. This lack of attachment explains why the wing top skin is floating up and down so much.
Because this gap runs the length of the wing the majority of the supports I will not be able to reach to add additional glue. Is my understanding was that the top and bottom composite skin being attached to the vertical supports are what gave the wing its strength. Kind of like a engineered joist. So I am not sure how structurally sound this wing would be at 200mph or bank and yank turns. Nor do I want to unnecessariky risk my turbine and electronics. Therefore I am seeking the advise of some fellow builders. Do you guys think this wing will be safe?
Thanks

This is the landing gear area. You can see a lack of glue and a large gap between the support and the wing skin.

This is near the wing tip, as you can see, the top skin is still not attached

Gap between the wing skin and the lengthwise support.
