Finished working with the Ailerons by starting with Section 21-4 Step 1. Riveted all parts of the Ailerons together per Section 21-4, 21-5, 21-6, 21-7. Section 21-8 mounted the Aileron control hardware. I torqued the bolts/nuts and torque sealed the nuts.
Packed the left and right Ailerons away for safe storage.
