AILERON RIGGING. Ball Bearing Installation

aileronriggingballbearinginstallation.jpg

I noticed that the screws holding the aileron bearings in place would not sit flat against the flange. This actually deformed the ball bearing case when tightened in place in the rear aileron bracket, causing an abnormal friction when rotating the bearing and giving the impression that it was damaged. By removing the bearing, the deformity was eliminated and the bearing was back to proper functioning. To resolve the problem, I Dremel-grinded AN960-416 washers to fit in place and level the screw heads against the bearing flanges.
