<p>A method (200) of inspecting an aircraft structure, the method comprising: disposing (204) a two-dimensional array (12) of ultrasonic pulse-echo sensors (18) onto a surface (70) of an aircraft structure; sending (206, 208) from each particular sensor (18) an ultrasonic pulse into the surface (70); receiving (210) by each particular sensor (18) an ultrasonic echo signal resulting from the sending of the ultrasonic pulse by the particular sensor (18); graphically displaying (220) an image of damage (120, 124) within the aircraft structure, the image defined by a two-dimensional matrix of pixels each of which corresponds to a particular one of the sensors (18); determining (222) whether the damage satisfies a predetermined criterion, and selecting (222) a mode of returning the aircraft structure to flying service based on the determination of whether the damage satisfies a predetermined criterion.</p> |
