In order to guarantee the airworthiness of aircrafts that are suspect to sustain the structural damage, it is necessary in the first place to visually inspect the aircraft. In many cases, the visual inspection of external areas is performed in regions with restrict access, so that the inspectors are required to use aircraft maintenance access stands and docking systems. For these latter the assessment tends to be expensive and time-consuming. Therefore, in order to reduce Aircraft on Ground (AOG) expenses, Autaza developed a drone inspection system which comprises hardware and software for automatic flight and visual defect detection.
