If you have an LCD wing you can unzip the zipper on the top arc of the wing pull out the wing and patch it. If it is a small leak you can try aqua seal or something a local dive shop may have. If you have the Torus wing then it is more complicated. You would need to use a seam ripper to open the stitching to get at the inner bladder, patch it, and then have someone sew it up being careful not to puncture the wing again with the needle.
It would be best for DSS to make the repair but for the cost of the repair, shipping, and any customs duty you may need to pay it may not be worth it.
