Brief Description: Drill Stiffeners to Left Aileron
Completed the edge finishing on the aileron skin with Scotchbrite pad. Cleco'd the stiffeners on one side of the skin with a cleco in every other hole and match drilled the skin. Moved the cleco's and repeated for remaining holes. Flipped the skin and repeated the process untill all holes were drilled. Removed the stiffeners and deburred the stiffeners inside and out, then scuffed with scotchbrite to prepare for dimpling. I marked all the stiffeners to put them back in the same place they were match drilled.
