Brief Description: Right Side Upright Doubler and Side Doubler
Installed the right side Upright Doubler which connects the two wing uprights with the top longeron and gains significant rigidity by riveting to the skin. This was a straightforward back-drilling job.
I installed the right Side Doubler which connects the forward Gear Upright with the aft Wing Upright and integrates with a previously-installed gusset connecting those same two uprights across the cabin floor. This section of the airplan is now completely rigid.
Right Upright Doubler drilled and clecoed. The Side Doubler rivet holes just to the lower left.
