I begin by installing the forward bulkhead, which consist of two stiffeners installing vertically on the skin. They needed to be fluted a bit, and the upper tab had to be tweaked. Then a rather bulky aluminium part gets attached to the longerons and skin, it will help support the main gear leg. It's visible on the left side of the picture with the white label.



Then I prepare the parts needed to install the fuel tank bracket. The wings have three anchoring points on the fuselage : main spar to the main bulkhead, rear spar to the seat bulkhead and fuel tank to the forward bulkhead. The bracket will be bolted to a piece of angle that is installed inside the fuselage, two spacers are also needed. Here are the parts for the right side.



The angle is clecoed on, drilled in a few steps to be bolted and riveted. On the picture you can see the upper bolt, the two spacers are invisible between the angle and the skin.



Here is a picture of the bracket from outside.



Then I reclecoed the forward lower skin to drill the last hole on the angle, it also has to be countersunk to accomodate a countersunk screw. The countersink has to be quite deep.
