Aircraft maintenance is essential to ensure the safety of passengers and crew, and the airworthiness of the aircraft. The use of drones to visually inspect aircraft improves the accuracy and speed of inspections, reduces aircraft downtime and increases the safety of maintainers. Drones capture high-resolution images around the aircraft, from which a 3 dimensional model is built using photogrammetry. The desire is to improve the current process, simplify it, speed it up and, above all, increase the level of safety. In this thesis we firstly examined the solutions and problems of visual inspections so far. Then we presented the process of creating a 3 dimensional model using photogrammetric software. The quality of 3D model was not sufficient enough for visual inspection needs. We have found that the current visual inspection process cannot be replaced, despite the reduction in inspection time. Finally, we presented the possibilities for further refinement and application.
