Use this as a pre-audit self-assessment. The real audit uses the current Nadcap checklists for your commodity in eAuditNet, so download those from PRI for the exact questions. Critical items are those most often raised as findings.

How to use this checklist

Run the self-assessment two to three months before the audit, walk the floor with it, and record evidence for every tick. Start with the current checklists from eAuditNet for your commodity, because Nadcap updates them and the self-assessment you submit must use the latest revision. Use this list to find gaps fast, then fix them while there is time to show corrective action. Export it to PDF for the shop floor or Excel to track owners and dates.

Re-walk the floor a week before the audit

What Nadcap auditors examine

Nadcap, administered by PRI, audits special processes against the AC7004 quality system requirements plus commodity-specific checklists. For non-destructive testing, those checklists cover procedures, personnel qualification under NAS 410, equipment, reference standards, and technique-specific controls. Auditors choose jobs and trace them from contract review through to the final report. They check that what is written matches what is done, so the strongest preparation is an end-to-end job trace of a recent order.

The NDT variant

NDT checklists are among the most detailed, because results rely on people and reference standards. Expect questions about the written practice, Level 3 oversight, system performance checks, light levels, bath controls, calibration and reject control. Complete only the method rows for processes in your scope. If you use more than one method, review each separately, since a finding in one can put the entire scope at risk.

Common causes of findings

Frequent findings include outdated procedures at the work station, overdue calibration, gaps in training or recertification records, incomplete process logs and corrective actions that fix the symptom but not the cause. Another is poor flowdown of customer requirements to the router. Treat each as a system issue, not an individual error.

Frequently Asked Questions

What checklists does a Nadcap audit use?

Audits use the AC7004 quality system checklist plus the commodity-specific checklist for each process, such as the NDT checklist and its method supplements. Download current versions from eAuditNet or PRI, because they are revised periodically.

When should the self-assessment be submitted?

The supplier completes the pre-audit self-assessment in eAuditNet before the audit, within the deadline PRI sets. Do it honestly: the auditor compares it against what they see, and gaps you identify yourself show maturity.

What NDT personnel standard is used?

Most aerospace NDT work uses a written practice that meets NAS 410 or an equivalent customer requirement. The Level 3 responsible for the procedures and personnel qualification must hold current certification, and the checklist items above help you confirm the records.

Is this the official Nadcap checklist?

No. It is a preparation aid built from common audit themes. The official checklists and requirements come from PRI and your prime customers, and they take precedence.
