NDI stands for which term?

• A. Non-destructive inspection
• B. Normalized data inspection
• C. New diagnostic inspection
• D. Nuclear damage inspection

Answer: (A)

NDI refers to inspecting materials or structures without causing damage, using techniques that can detect defects or wear while the part remains in service. Among the choices, Non-destructive inspection is the best fit for the acronym NDI, since it directly describes the practice of checking for issues without destroying or altering the part. The other phrases aren’t standard terms associated with this acronym in aviation maintenance, so they don’t match what NDI represents. In practice, NDI encompasses methods such as visual inspection, ultrasonic testing, radiography, magnetic particle, and dye penetrant testing, all aimed at finding cracks, corrosion, or other flaws without taking the component out of service.
