A system for nondestructive inspection of structures. The system includes an omni-directional unmanned aerial vehicle (UAV) and a support arm extending outward from the UAV body from a first end attached to the body to a second distal end, which is used to support a nondestructive testing (NDT) sensor. The system includes an autopilot module stabilizing the flight of the omni-directional platform. The autopilot includes a wall-tracking mode, which determines the normal of the structure's surface, and the omni-directional UAV is stabilized to fly with the support arm aligned with normal to the surface and with the second end proximate to the surface with the UAV body in any orientation in space. The UAV operates to follow a flight path whereby a longitudinal axis of the support arm coincides with the normal and the sensor is positioned in predefined measurement position relative to the structure surface to take the measurements.
