Preparing lower inboard wing skins, 3h

Category: 3: Wings (Total 309h) — Steffen @ 20:28 — Hours: 3

Yesterday I started preparing the wing skins. First I hole- and edgedeburred the wing walk-way doublers.

Then I started out on the lower inboard wing skins. I had to countersink for the access panel nutplate rivets. I am using NAS1097 rivets here instead of dimpling. These rivets have a smaller head than standard rivets, so you can countersink without enlarging the holes. I finished preparing both lower inboard skins tonight. I will prime them tomorrow.
