Intermittently, I worked over the last three days. I am busy with the right wing. Previous occasion, both the front and rear spot we are prepared, the wing trust was bolted and torqued. The ribs were also Prepared, straightened, Deburred, and primed. All the metal to metal surfaces were primed. I am in the process of attaching the aileron and slab hinge arms, aileron bell crank, Teleflex etc. to the proper ribs. On rib number six, the angle brackets attaching the rib to the rear spar was over drilled, and received a bigger rivet.
