Gonçalves, P., Sobral, J. and Ferreira, L. (2016), “Safety Assessment of Unmanned Aerial Vehicle Systems: Practical Application”, IMA World Maintenance Forum 2016, April, Lugano, Switzerland

The focus of the research centre of Portuguese Air Force Academy in recent years has been the projects involving unmanned aerial vehicles as a result of its extensive experience in the development and construction of unmanned aircraft of Class I (with mass up to 25kg). The experience and knowledge accumulated over years in this type of aircraft, was transferred to larger aircraft that required to be subject to a prior airworthiness certification process for its operation. This paper shows the result of work in the evaluation of the safety of military UAV ANTEX systems. It will be presented the methodologies (SAE ARP 4761) employed in carrying out the safety assessment of ANTEX, as well as the tools (FMECA, FTA) used to evaluate and classify the identified risks. The results obtained allowed to identify and define critical areas and corrective actions that have made the level of risk identified acceptable to the regulatory authority, obtaining in this way too the guidelines for the development of the maintenance plan that will ensure the continued airworthiness of the ANTEX UAV systems.
