How should VT indications be documented?

• A. Only verbally.
• B. In a general maintenance log only.
• C. In a lab notebook with no supporting evidence.
• D. In inspection records with location, size/estimate, type, lighting conditions, surface condition, disposition; supported by photos or drawings.

Answer: (D)

Documenting VT indications relies on a complete, traceable record that captures exactly what was found and how it was observed, so the finding can be reviewed, acted upon, and verified later. The best practice is to record in inspection records with the following details: where the indication is located, the size or an estimate of its extent, what type of defect it is, the lighting conditions under which it was observed, the surface condition at the time of inspection, and the disposition (accepted, rejected, or require repair). Supporting evidence such as photos or drawings should accompany the record.

Why this is the best approach: location pins the defect to a specific spot on the item, size/estimate communicates the magnitude, and type classifies the defect for proper response. Lighting conditions directly affect visibility and the ability to distinguish features, so noting them prevents misinterpretation. Surface condition matters because coatings, cleanliness, or corrosion can hide or alter appearances. Disposition shows the action taken or required, closing the loop on the inspection. Photos or drawings provide an objective, verifiable record that can be reviewed or compared in future inspections.

Verbal-only notes lack traceability; a general maintenance log is too broad for VT specifics; a lab notebook with no supporting evidence isn’t verifiable.
