Safety/reliability analyses of GA aircraft in design and certification stage in Czech republic

Abstract The purpose of the paper was to provide the reader with basic insight into practical problems solved in the Czech aerospace industry and with a list of requirements and recommendations of civil airworthiness regulations on the field of reliability. This includes a short historical introduction, a list of basic requirements, and recommendations of the regulations for different aircraft categories. The general aviation category (sport airplanes and small transport airplanes) is covered in more depth. Recommended procedures for reliability analyses are also covered (with a focus on the design and certification process), including a brief summary of their utilization in the Czech aerospace industry. Special attention is paid on the activities of the Brno University of Technology (and its Institute of Aerospace Engineering). A practical example of safety assessment based on an electronic avionic system for small GA aircraft is also provided.
