Non-Destructive Testing (NDT) Practice Test

When is an unscheduled inspection performed?

1. Only when a defect is reported

2. Based on regular schedules

3. Always after repairs

4. All of the above

The correct answer is: All of the above

An unscheduled inspection is characterized by its occurrence outside of a predetermined timeline or schedule. It can take place for various reasons, including but not limited to unexpected circumstances or findings. One primary scenario for an unscheduled inspection is when a defect is reported. In such cases, it is crucial to assess the specific area where the defect was identified to evaluate its implications and determine necessary corrective actions. This helps in maintaining safety, compliance, and operational integrity. Furthermore, unscheduled inspections can also follow repairs. After components or systems undergo repair, an inspection is often warranted to ensure that the repairs were carried out correctly and that the integrity of the system is restored. This acts as a quality assurance measure to validate the effectiveness of the repair work. While regular schedules are vital for systematic inspections, unscheduled inspections serve as a responsive measure to unforeseen issues that may arise. Hence, all of these instances—reporting of defects, post-repair evaluations, and addressing other unpredicted conditions—support the rationale for conducting unscheduled inspections.
