Brief Description: Left wing tank nose rib proseal
Installing the left tank inboard nose rib was a little challenge. The tank is folded from the factory, but NOT the shape of the leading edge. The inboard nose rib had to be placed exactely where it needed to be, alligned with the dimples in the skin. Not only is it slippery, but the holes are hidden in proseal. Once it was lined up, it sat rit in. After riveting, I used the rest of the proseal made for this rib to seal the rest of the edge. After the edge was done, I removed the tape that protected the upper rib mating surfaces which will be the last rib installed prior to closing the tank.
