How does the inspector determine what kind of inspection to perform for a particular detail part?

• A. Consult the customer
• B. Perform random sampling
• C. Choose the most convenient method
• D. Look at the plan

Answer: (D)

The method of inspection is determined by the plan. The plan is the official instruction that lays out exactly what features to inspect on a detail part, how to inspect them (the measurement method, tools, and techniques), the sampling approach if any, and the acceptance criteria or tolerances. By reviewing the plan (and related drawings and specifications), the inspector follows the prescribed inspection type—whether it’s 100% measurement, sampling per a specified plan, a nondestructive test, or a visual/functional check—along with the required instruments and procedures. This ensures consistency, traceability, and compliance with contractual and regulatory requirements. Other ideas, like consulting the customer for how to inspect, performing random sampling without a plan, or choosing the easiest method, don’t provide the documented, enforceable instruction needed for proper quality control. The plan is the authoritative source that tells you exactly how to inspect this part.
