Yesterday while doing wind-up turns for testing, I heard a slight pop sound at exactly 2.5G and returned for inspection. My right wing, apparently in the stub wing makes a slight pop like there is something sticking and tension releasing when the wing is lifted and then pushed down again. I inspected the spar faces, wing attach brackets, and checked bolt torque and all appears normal. The airplane flew normally and there was no indication of overstress. When flexing the wing up and down if definitely seems like something in the wing is building a little tension and releasing it in a slight pop. Anyone experience this in your KR?
