A multi-sensor NDI probe having means for self-alignment of the NDI sensors in conjunction with the movement of the sensor suite along the length of a hollow elongated stiffener having a rounded cap. The apparatus comprises a large-radius curved ultrasonic transducer array with cylindrical focus, which provides complete coverage for the rounded cap, two small-radius convex curved transducer arrays for NDI of the lower outside radii, and two linear transducer arrays for NDI of the sides of the stiffener. The five transducer arrays are supported by respective compliant assemblies which facilitate proper adjustment of the location (i.e., position and orientation) of the transducer arrays during scanning. The positions of the transducer arrays are adjusted to account for geometric variations in the stiffener.
