Non-destructive testing (NDT) is a way to detect and evaluate flaws in materials. Within aerospace NDT plays a vital role in the design, manufacture and maintenance of aircraft. The simplest and most accurate way of testing materials and components is often to test them to destruction.

Fluorescent penetrant inspection (FPI) is a type of dye penetrant inspection in which a fluorescent dye is applied to the surface of a non porous material in order to detect defects that may compromise the integrity or quality of the part in question. FPI is noted for its low cost and simple process, and is used widely in a variety of industries.
Magnetic particle Inspection (MPI) is a nondestructive testing (NDT) process for detecting surface and shallow subsurface discontinuities in ferromagnetic materials such as iron, nickel, cobalt, and some of their alloys.
Nital etch is a non-destructive test that is used to determine if the material properties of a part have been impacted due to overheating during machining.
