Almost finished building my Ucando, and then i notice it, i pick the wing up to move it and it crackled (as in split wood underneath the covering), never done it before, don't know how this happened, but it did, so what do i do now ??

It's on the leading edge of the wing, 12 inches in from the left hand side - can someone tell me how to fix this, as in what to do in idiots terms (never had to fix one yet), can i peel the cover back and glue it then re-seal ??? Or do i have to get a new bit of covering for that bit or what?

I really have no idea, please help, thanks !!
