Non destructive inspection describes what?

• A. A destructive test
• B. An inspection that does not damage the part
• C. A qualitative judgment
• D. A maintenance check

Answer: (B)

Non-destructive inspection focuses on evaluating a part’s condition without damaging it. The goal is to detect flaws such as cracks, corrosion, voids, or delaminations while the component remains intact and usable. It relies on techniques that do not alter the part’s serviceability—visual inspection, ultrasonic testing, radiography, magnetic particle, dye penetrant, eddy current, and thermography are common examples. Because the part isn’t damaged, these inspections can be repeated over time to monitor aging and guide maintenance decisions. This is different from destructive testing, where the part is altered or destroyed to learn about material properties. Some inspections yield a yes/no verdict about the presence of a flaw, while others quantify flaw size or depth, but the core idea is evaluating integrity without causing harm to the part.
