Degradation and failure of aircraft wiring insulation results in potential flight safety critical system failure or in smoke and fire due to arcing. Therefore, there is a need to detect any defect within the physical structure of the aged wire before any malfunction takes place. There are different types of Non-Destructive Testing (NDT) techniques available for aircraft wiring inspection and one of them is the ultrasonic guided waves technique. Using guided wave ultrasonics, inspection can be carried out for a long distance from a single location. In order to understand the behaviour of guided waves in aircraft wiring, a modelling tool was used to simulate and predict the behaviour of guided wave characteristics in wires with respect to the stiffness property of the insulation. Artificial defects were introduced into the wire. Finally, the modelling results have been validated experimentally.
