How do you inspect pin protrusion with the gauge?

The process of inspecting pin protrusion typically involves assessing how far the pin extends beyond the surface of the structure. By placing the gauge on the surface of the structure, you can directly measure the distance the pin protrudes. This method ensures that the gauge sits flat against the surface, providing an accurate reading of the protrusion in relation to the structure’s intended design specifications.

Using the gauge in this manner is essential, as it allows for a precise evaluation of the pin's extension, which is critical for safety and performance within aerospace assembly. The correct amount of protrusion is vital for ensuring that the pin engages properly into components and that structural integrity is maintained. In contrast, other methods such as using a ruler or comparing with a standard do not directly measure the interaction between the pin and the structure surface, which is necessary for determining whether the installation meets the engineering design requirements.
