Which of the following is NOT listed as a type of inspection?

• A. Visual inspection
• B. Thermal imaging inspection
• C. Corrective action assessment (discrepancy determination)
• D. Functional/operational inspection

Answer: (B)

In this TO, inspection types are defined as visual inspection, functional/operational inspection, and corrective action assessment (discrepancy determination). Thermal imaging inspection is a diagnostic technique used to detect heat patterns, but it isn’t listed as a separate inspection type in the TO’s categories. It can augment other inspections by revealing issues that aren’t obvious to the naked eye, but it does not stand as its own inspection category in the framework. So, while useful, it isn’t identified as a distinct type of inspection, which is why it’s the correct answer for what is not listed. For the others: visual inspection is sight-based checking; functional/operational inspection verifies that equipment works as intended; corrective action assessment determines discrepancies and needed corrective actions.
