I am not an expert here, but my understanding is that if there is stress corrosion in the rivet it will show up. I know ultrasound can detect intergranular corrosion. Also, the SB specifically mentions problems at the base of the shop heat, IIRC, which is a lot closer to the probe than the other end of the rivet. Anyhow, I believe that the ultrasonic inspection can detect these areas of concern. Anyone else?
