Brief Description: Main Gear Hydraulic Line - Blkhd Fitting Provision
I was looking through the manuals at the hydraulic tube routing through the wing for the main gear actuators. I decided that I liked the method shown in the GII manual better than the GI. I marked the location on the rear spar shear webs were the -4 bulkhead unions will pass through the spar. On the forward side of the shear web I will dish out an oval shape in the foam and layup two plys of glass. To do that I need a two ply laminate on the aft side of the web to dig down to and lay up against.
I cut the outer oval shape through the layups on the forward side of the web. Then I layed up a two ply laminate about four inches wide on the opposite side of the shear web and left to cure.
