Nadcap AC 7120: from initial assessment to robust audit readiness
Nadcap AC 7120 assesses printed board assembly manufacturing for demanding aerospace applications. Controlled processes and objective evidence are central. A well-written quality manual alone is not enough: requirements must align across work instructions, manufacturing practice and records.
I help companies establish that connection through structured readiness analysis, practical process optimisation and realistic mock audits. The applicable criteria are determined from your scope and the current official audit documents. The following steps describe the consulting and preparation process; they do not replace official audit criteria.
How we prepare for your Nadcap audit
- 01
Define the scope and applicable requirements
First, we establish which assembly processes, products and sites are included in the audit scope. The applicable edition of AC 7120, relevant supplemental audit criteria and customer requirements determine the assessment. A requirements matrix links each requirement to its implementation and supporting evidence.
- 02
Gap analysis and an actionable plan
We compare work instructions, process approvals and records with actual shop-floor practice. Sampling a job through its production steps reveals gaps. You receive a prioritised action plan with owners, deadlines and expected evidence, rather than just a list of missing documents.
- 03
Secure the processes and conduct a mock audit
Your team implements the actions and collects reliable evidence. An internal first-party audit or mock audit checks effectiveness under realistic conditions: employees explain their work, job records are traced and inspection results are linked to requirements. Outstanding issues are addressed before the external audit.
- 04
External audit and responding to findings
The Nadcap audit assesses documentation, process implementation and evidence within the agreed scope. If nonconformances are raised, I support immediate actions, root-cause analysis, permanent corrective actions and clear evidence packages. Submission and follow-up follow the applicable PRI requirements and deadlines.
- 05
Verify effectiveness and maintain readiness
After implementation, we verify that the root cause has been removed and the issue does not recur. Internal audits, controlled changes and maintained records help preserve audit readiness between audits. Accreditation decisions belong to the Nadcap process, not to the consultant.
Common finding scenarios: areas worth checking
The following examples are practical assessment areas, not a ranking or an exhaustive list of AC 7120 requirements. Their relevance depends on your audit scope and applicable criteria.
Documentation does not match shop-floor practice
A procedure describes a process performed differently at the workstation, or an obsolete revision is in use. We assess document control, compare requirements with actual practice and establish traceable changes.
Process and inspection evidence is incomplete
Missing approvals, incomplete job records or inspection results that cannot be clearly linked to a job weaken evidence of conformity. We trace selected jobs from incoming material through assembly to inspection and close evidence gaps.
Personnel and equipment evidence is insufficient
Depending on the audit scope, relevant areas may include qualifications for the work performed, equipment suitability, inspection equipment control and ESD handling. The required implementation must be evidenced, not merely described.
Corrective actions address symptoms rather than causes
Additional training alone does not automatically remove the cause of a nonconformance. Root Cause & Corrective Action (RCCA) separates immediate correction, systemic cause, permanent action and effectiveness verification, producing a traceable response to the finding.
DIN EN 9100 and Nadcap: two levels, one coordinated system
ISO 9001 provides the quality management foundation. DIN EN 9100 / AS 9100 adds requirements for aerospace, space and defence. Nadcap AC 7120 focuses on the technical assessment of printed board assembly. DIN EN 9100 certification does not automatically replace Nadcap accreditation, nor does Nadcap cover the entire management system.
Shared areas such as document control, competence, traceability, internal audits and corrective actions should nevertheless align. I help you use existing processes effectively and integrate the additional technical evidence without unnecessary parallel structures.
