A method for determining a location of incipient damage of an object comprises insonifying the object at a plurality of locations using ultrasonic signals during an inspection, acquiring signals indicative of a possible damage condition from the plurality of locations of the insonified object in said inspection, determining a value for each of the locations to indicate accumulated damage by mathematically combining the acquired signals from said inspection and at least a portion of prior inspections, and comparing the values of the plurality of locations to determine a location indicating possible incipient damage.
