What is the purpose of Non Destructive Inspection (NDI)?

The purpose of Non Destructive Inspection (NDI) is primarily to conduct non-destructive testing on aircraft components. This technique is crucial in the maintenance and safety of aircraft, as it allows for the evaluation of structural integrity without causing any damage to the parts being inspected. NDI techniques can identify flaws, cracks, or defects that could compromise the performance and safety of an aircraft, ensuring that the aircraft remains in a condition fit for service.

This method is essential in aviation, where safety and reliability are of utmost importance. Maintaining the integrity of materials and structures while avoiding the need for replacements unless necessary helps in cost management and operational efficiency.
