Brief Description:	Left Aileron
Today I de-vinyled the stiffener rivet lines on the replacement left aileron skin, dimpled the skin and stiffeners, and backriveted the stiffeners to the skin. I had completed dimpling the upper side of the skin and had just started on the bottom when it occurred to me that I hadn't deburred the exterior of the holes. They weren't bad enough to worry about, but I did give them a turn of the deburring tool before continuing with the dimpling. No rivet count update today, since these have already been counted on the first iteration of the left aileron.
