14-5: Step 1: Applied protective tape to cover the stepped bars from damage while riveting ribs. Step 2: Clecoed all L-Wing ribs to L-Spar. I had already performed the final-drill of all the #40 forward most hose in the forward tab ofall the ribs. Instructions said only to do the seven inboard W-1011 ribs. I probably should have waited to do as instructed. It is apparent to me now why that was done as the plan is to final drill with the wing skins in place.
