How are nonconformance classifications defined by severity?

• A. Critical, Major, Minor; used to prioritize containment and corrective actions.
• B. High, Medium, Low; used to schedule rework.
• C. Severe, Moderate, Light; used to determine warranty.
• D. Immediate, Delayed, None; used to escalate to management.

Answer: (A)

Nonconformance severity is shown with three levels—critical, major, and minor—so teams know how urgently to act. A critical issue indicates a safety risk or regulatory noncompliance that could affect flightworthiness, requiring immediate containment and rapid disposition with top-priority corrective action. A major issue has a significant impact on function or compliance but does not pose an immediate safety hazard, so it still needs prompt investigation and corrective action. A minor issue has little or no effect on safety or operation, often being cosmetic or easily fixed during routine maintenance. This three-tier setup keeps responses consistent, helps allocate resources wisely, and ensures timely closure of nonconformances. Other term sets don’t align with how nonconformances are typically handled, as they either mix general risk labels or emphasize escalation timing or warranties rather than the severity-driven actions the classification is meant to guide.
