When might non-destructive testing (NDT) be used in ALRE maintenance?

• A. For inspecting structural components for cracks and integrity without disassembly
• B. For performing routine lubrication
• C. For adjusting hydraulic fluid temperature
• D. For replacing worn gears

Answer: (A)

Non-destructive testing is used to identify flaws in materials and welds without taking the component apart. In ALRE maintenance this means you can check structural components for cracks, corrosion, or other integrity concerns while the part remains installed or during scheduled maintenance, avoiding unnecessary disassembly and downtime. Techniques like magnetic particle, liquid penetrant, eddy current, ultrasonic, and radiographic methods reveal surface and subsurface defects that could compromise safety in launch and recovery operations. This approach supports early defect detection and safe operation, which is why inspecting for cracks and overall integrity without disassembly is when NDT is most appropriate. Routine lubrication, adjusting hydraulic fluid temperature, or replacing worn gears are direct servicing or replacement tasks and do not involve evaluating a part for hidden flaws without disassembly, so NDT isn’t used for those activities.
