The guided wave technique is an emerging inspection procedure for the inspection of adhesively bonded lap splice joints and tear straps in aging aircraft. Due to inspection of joint locations with area scanning techniques, the evaluation of a joint region with a line scanning makes the guided wave technique a potential candidate for fast joint inspection and probably for further data evaluation for characterization of the detected imperfections. An approach to characterize or classify the inspection region is done by feature selection in order to acquire physically based information. Results are presented from lab specimens and from measurements on a Boeing 737-222 specimen manufactured in 1968.
