				| Started work on the A-905 aileron ribs
 This is where I have to be careful, what's top, what's bottom, what's left, etc. I laid out the A-905 ribs on the left aileron first, because that's what is shown in the drawing, then by process of elimination, I laid out the right aileron. These ribs have tooling holes in the bottom of the rib web to let you know that that is bottom of the rib.
