Abstract
A device and method for checking an integrity of a glue joint that connects one portion of a body box and a body skin are provided. The body box and body skin connected by the glue joint define an inner volume therebetween. The method includes arranging at least one ultrasound sensing device in the inner volume; emitting a pressurized directional air jet opposite a predetermined area of the glue joint; recording a noise level detected by the ultrasound sensing device in the inner volume; and determining an integrity defect in the glue joint according to the recorded noise level.
