Abstract : The Aging Aircraft Nondestructive Inspect ion Validation Center (AANC) at Sandia National Laboratories is charged by the FAA to support technology transfer, technology assessment, and technology validation. A key task of the Center is to establish and apply a consistent and systematic methodology to assess the reliability of inspections through laboratory and field experiments. Under this mandate the Nortec-3O Eddyscan inspection system was evaluated using procedures and test specimens originally developed to assess the reliability of eddy current inspections of rivet holes in a simulated Boeing lap splice. The extent and location of cracks in the upper skins were unknown to the inspector using the eouipment. The results of the experiment are discussed in terms of probability of detection curves. Comparisons are made to baseline laboratory detection data obtained using other eddy current equipment. eddy current inspection reliability
