With the growing number of aging passenger aircraft in the fleet, improve nondestructive inspection (NDI) techniques are being investigated to insure the reliability of the fuselage structures of these aircraft. The Boeing Commercial Airplane Group is evaluating nondestructive testing techniques for detecting disbonds in aircraft structures. One of the techniques under evaluation is electronic shearography. This paper describes the disbond inspection of aluminum lap joint coupons with electronic shearography. Inspection results from the simulated lap joint coupons, containing programmed defects, are reported.
