Abstract

The economic drive towards using military aircraft beyond their initial design life has created a great interest in damage-tolerance (DT) based maintenance philosophy. The DT approach relies on routine nondestructive inspections (NDI) and requires the NDI performance to be quantified in terms of probability of detection (POD). From the POD-flaw size relationship, the detection limit of inspection techniques, in terms of flaw size, is established and then used to calculate safe inspection interval [1].
