In the munitions inspection process, when is a periodic inspection required to be performed?

• A. Only when there is a suspected discrepancy in shipment description
• B. Upon initial receipt of all lots
• C. When defects found during receiving inspections make a lot's serviceability questionable
• D. After a yearly cycle

Answer: (C)

Periodic inspection is driven by condition: you perform it when defects found during receiving inspections make a lot’s serviceability questionable. If Receiving reveals issues that could affect safety or performance, you don’t assume the lot is still acceptable—you recheck it to confirm it remains serviceable before use or release. This approach isn’t about discrepancies in shipment descriptions, isn’t simply the initial receipt step for every lot, and isn’t a fixed yearly calendar requirement—it's triggered by the observed condition that could compromise serviceability.
