Inspection, Audit, and Surveillance Techniques
Oversight Toolkit
ANAC oversight relies on inspections, audits, and surveillance. Candidates must understand the difference: inspection examines a specific product or process; audit evaluates a system against requirements; surveillance is ongoing monitoring. Key techniques include document review, interviews, sampling, and direct observation. Risk-based oversight (RBO) is increasingly used, focusing resources on higher-risk areas. Inspectors must know how to plan an inspection, gather objective evidence, classify findings (non-compliance, observation, opportunity for improvement), and follow up on corrective actions.
Concepts to Master
Understand the audit cycle: planning, opening meeting, evidence collection, finding classification, closing meeting, and corrective action verification. Know the importance of objectivity and the use of checklists. Be familiar with the concept of root cause analysis and the difference between correction (fixing the symptom) and corrective action (eliminating the cause). Also know the requirements for recordkeeping of surveillance activities and the escalation process for unresolved findings.
Traps
A frequent trap is treating an observation as a finding, or failing to verify that corrective actions are effective. Another is not distinguishing between a system audit and a product inspection. Also watch for the assumption that a finding automatically leads to enforcement; the response depends on the severity and the operator's corrective action.
Worked Example / Rule of Thumb
Rule: "No finding without objective evidence; no closure without verification." Example: During an audit of a maintenance organization, an inspector finds that calibration records for torque wrenches are missing. The finding is a non-compliance with RBAC 145 recordkeeping requirements. The organization must correct the missing records (correction) and implement a process to ensure future calibration records are kept (corrective action). The inspector verifies the corrective action at a follow-up.
