Which method of magnetic particle inspection is most frequently utilized to inspect aircraft parts?

The method of magnetic particle inspection that is most frequently utilized to inspect aircraft parts is the continuous method. This technique involves the application of a magnetic field to the component under examination while simultaneously dispersing magnetic particles over its surface. The continuous magnetic field allows for immediate detection of surface and near-surface discontinuities, as the particles will cluster at any flaws, making them visible.

The continuous method is particularly well-suited for inspecting aircraft components because it can be employed on a variety of materials and geometries, and it provides real-time results. This is critical in aerospace applications, where safety and reliability are of utmost importance. The effectiveness of this method in identifying even the tiniest of defects makes it the preferred choice among inspectors in this field.

In contrast, while other methods such as static and residual magnetic particle inspections are valuable, they may not offer the same level of real-time feedback or ease of use as the continuous method. Capacitive discharge, though useful for certain applications, is less common in the context of magnetic particle inspection for aircraft parts. Each method has its own advantages, but the continuous method stands out for the specific requirements of aircraft inspection.
