Abstract: Aspects of the invention are directed to a method and a system for detecting weakening of the adhesion strength between two or more joint surfaces of two or more structural elements. The system includes one or more Load Pins (LPs) and a controller. The one or more LPs may be inserted through the two or more structural elements such, perpendicular to the two or joint surfaces, such that no shear load is initially sensed by the LP. The system further includes a controller be configured to: upon receiving from the one or more LPs a shear load value, detect the weakening of the adhesion strength between the two or more joint surfaces.
