To replace the broken material a straightedge was used to make a cut spanning at least two ribs. This will make it easier to add new balsa later as it'll be supported by the ribs. A little time with a knife will help remove the extra material still glued to the ribs. To make this repair a little easier, all of the ribs in this section of the wing are made from light ply, so none were damaged. If a rib was damaged the repairs would be a little more involved.
After the ribs are cleaned off, patch panels are cut and glued into place. Since this is a curved part of the wing the balsa is soaked in warm water (or you could use Windex) for a few seconds, which softens it enough to handle the curve more easily. When it's glued in place, plenty of pins hold it while the glue dries. There is one small chip in the picture which needs to be taken care of. Tomorrow morning it should be ready to plane and sand, and any low spots will be filled with putty as needed before covering. Either way, the plan is to have it done tomorrow.
