The present invention relates to the detection of cracks in metals. More particularly, this invention relates to a method for using eddy current to inspect metal aircraft components for cracks. The present invention utilizes eddy current inspection to improve the accuracy of depth measurements for cracks located below an aircraft's surface. As a result, the scatter of the acquired POD data measurements is reduced resulting in a more effective inspection method for the aircraft industry.
