    Požiadavky na harmonizáciu údržby ultraľahkých lietadiel
    (University of Zilina, 2022) Škultéty, Filip; Čerňan, Jozef; Janovec, Michal; Chodelka, Frederik
    The exact definition of an Ultralight Aircraft is still very diverse, especially in the European region. Internationally, there are various Ultralight Aircraft (UL) classes with nationally varying certification regulations. Accordingly, Ultralight Aircraft is used colloquially ore or less comprehensively for Very Light Aircraft or Light-Sport Aircraft. However, they are subject to much stricter certification nd maintenance regulations. This paper aims to compare the current legal situation in the European Union countries, extract the best practices, and propose how a new “AMC & GM” should define the laws and regulations to create the best possible vironment for UL airworthiness. This paper is written based on information and directions published on the websites of the esponsible uthorities of the respective countries, as well as communication with these authorities and first-hand knowledge obtained by conducting numerous interviews with people in the field of UL maintenance. The results indicate how different each country egulates the maintenance and continuing airworthiness of ULs and how important a harmonised regulation would be. It is specially important to have clarity as with larger aircraft and thus also to prevent numerous accidents and hazardous situations in the future.

    Possibilities of using 3D printing technology in production of aircraft components
    (University of Zilina, 2021) Šajbanová, Kristína; Čerňan, Jozef; Janovec, Michal
    The article provides the reader with a brief overview of the technology of industrial 3D printing used in the manufacturing process of aerospace technology. It includes analyses of the position of 3D printing in the aerospace industry and the forecast of its future development based on the marketing analysis of strengths / weaknesses, opportunities and threats. Many airlines and AMOs (Approved Maintenance Organizations) rely on externally supplied spare parts delivered over long distances. The whole process is expensive and time consuming and means a lost profit for the company. The performed SWOT analysis can therefore ultimately help the AMO manager to re-evaluate their production process in the light of the current innovative and progressive technology of industrial 3D printing.The aim of this work is to point out the existence of innovative 3D printing technology in aerospace production and to emphasize its preferences compared to conventional manufacturing techniques and procedures, thus providing a final perspective on the future of the 3D printing industry and its long-term sustainability
