True or False: When inspecting a drilled hole, the Go pin should pass completely through the assembly, while the NoGo pin should not pass at all.

The statement is true because it outlines the principle of using Go and NoGo pins in quality control and inspection processes for drilled holes. In this context, a Go pin is intended to fit into a hole or assembly to confirm that it meets the minimum size or tolerance requirements. If the Go pin passes completely through the assembly, it indicates that the hole is correctly sized and within the acceptable tolerance limits.

Conversely, the NoGo pin is designed to ensure that the hole does not exceed a specific size. If the NoGo pin does not pass through the hole at all, it confirms that the hole has not become oversized beyond the acceptable limits. Therefore, the successful interaction of both pins with the hole is critical for verifying that the assembly maintains its integrity and quality parameters.

The interplay of the Go and NoGo pins is a standard practice in manufacturing and assembly processes, not limited to certain materials or specific types of assemblies. Thus, the answer accurately reflects the general principle applied across various aerospace applications, supporting the importance of adhering to specified tolerances during inspections.
