Apparatus and methods are described for the improved throughput and increased reliability for inspection of critical surfaces on aircraft engine disks. Eddy current sensor arrays allow two-dimensional images to be generated for detection of cracks in regions with fretting damage. Background variations due to fretting damage and stress variations are also accommodated. These arrays are combined with instrumentation that permits parallel data acquisition for each sensing element and rapid inspection rates. Inflatable support structures behind the sensor array improve sensor durability and reduce fixturing requirements for the inspection.
