Video - Mag Particle Inspection of Aviation Pitch Change Fork
In this video from Aircraft Propeller Service in Lake Zurich, IL, see a live magnetic particle inspection of a pitch change fork. This general aviation propeller part is subject to degradation over time and must be inspected on a regular basis. This inspection was completed by Jon Burg, a nondestructive testing technical at Aircraft Propeller Service.

Magnetic particle inspection (MPI) is a nondestructive testing (NDT) method. An electric current is run through the magnetized component, and cracks or faults are identified by ultraviolet light.
