The next question is how is the phenolic tube held in place. I always use false ribs that the phenolic has to go through to give the wing strength.

If there is a false rib and it is broken, it won't do any good to just fix the sheeting as the phenolic tube will break through the sheeting with high g forces. If you built the wing, then you would know if a false rib was used or not.

In answer to getting the glue in the crack, go to eckard, wallgreens or some local pharmacy and purchase some 10cc syringes and some 23-25 guage needles. You may have to do a little explaining. At any rate, put the glue into the syringe and push the plunger as after you position the needle through the wing skin.

The syringes work better than anything for Robart Hinge Points also, especially if using epoxy. The Gorilla glue I used had a spout that could go into the hole nicely also.

Good luck
