Continuing with the right side rear spar, I dimpled and de-burred both aileron bracket doublers. I knew the upper flanges would need dimpling, but nothing was called out in the plans. Unsure of myself, I wouldn’t commit until I found another builder’s site that showed it! I also dimpled the upper spar flange coincident with the fork doubler as called out in the plans. Others report having difficulty getting access due to the acute angle of the flange, but I had no issues with my squeezer. I match drilled the inboard doublers. I did some de-burring of the newly drilled holes. I need to machine countersink a few holes, and the right rear spar should be ready to prime.
