A device and a method for ultrasonic testing by means of a local immersion technique of a stringer component section of a flat component are provided. The device includes a test head assembly mounted as moving floatingly by a holding device in the Y-direction longitudinally. The test head assembly includes: a test head that can be connected to an automatically actuated handling device and that can be moved by the handling device along the stringer; a test head holder; and a counter-holder coupled with the test head holder by an actuation element, wherein the actuation element is configured to steer the test head holder and the counter-holder from a closed position to an open position, the test head holder and the counter-holder being mounted floatingly along a guiding rail running in the X-direction transversely to the stringer, and fit, in a force-loaded manner, to each side surface of the stringer.
