Removal of cracks from rigging hardware must be verified by ____ before it is returning to service?

• A. Visual Inspection
• B. Non-Destructive Testing
• C. Destructive Testing
• D. Magnetic Testing

Answer: (B)

Verification after crack repair must be performed with non-destructive testing before returning to service. Non-destructive testing lets you confirm there are no remaining cracks or new flaws while keeping the part intact, which is essential for safety-critical rigging hardware. Visual inspection alone can miss small or subsurface cracks, so it isn’t enough by itself. Destructive testing would ruin the component and isn’t feasible for equipment that needs to be used again. Magnetic testing is one method within non-destructive testing, suitable for ferromagnetic materials, but the overall requirement is to verify with non-destructive means to ensure the repair holds under service loads. In practice, methods like magnetic particle inspection or liquid penetrant testing are commonly used to detect surface and near-surface defects after crack removal.
