Continued Sect 9-13, Step 6 & 7 for Trim Tab Spar; countersunk at hinge mounting rivets, and dimpled other flange. Step 8: Masked locations for 3 foam Ribs, per instructions sanded w/ 150 grit Alum Oxide paper.

| Adhesive bond zones for Foam Ribs and TE. |

| Not planning to Prime skins interior, since Alclad is still intact otherwise. |
Step 9 & 10: Dimpled all remaining holes for Trim Tab Skins. I checked Skin's dimpled holes fit into CS on Spar - found needed 1-2 clicks deeper on microstop. Now Skin fits tightly to Spar surface...ready to rivet. Glad I checked.
