What is the risk of mixing serviceable and unserviceable parts during inspection?

• A. Improved inventory control.
• B. Potential use of nonconforming parts.
• C. Faster repairs.
• D. No impact.

Answer: (B)

Mixing serviceable with unserviceable parts creates a real risk that a nonconforming item could slip into service. Serviceable parts have been verified to meet all required specifications and are approved for use, while unserviceable parts have defects or discrepancies that keep them from being used until they are repaired or properly disposed of. When these items are stored or handled together, inspection and sorting can be confused, increasing the chance that a nonconforming part is misidentified as acceptable and ends up being installed. The result can be a safety hazard, equipment failure, or noncompliance with standards.

To prevent this, unserviceable parts must be segregated, clearly tagged, and documented so they cannot be mistaken for serviceable items. Only parts that are verified as conforming should be accepted into service.
