Methods for thermographic inspection of structures are disclosed. An example method includes positioning at least one of a heat source or a camera in a cavity defined by a first side of a structure of an aircraft and positioning the other one of the heat source or the camera at a second side of the structure opposite the first side; applying heat to the least one of the first side or the second side of the structure; measuring thermal energy emitted from the other one of the first side or the second side opposite the heat source; and identifying a defect or inclusion of the structure based on the measured thermal energy.
