Abstract:
In the last five years, technical advances and regulatory pressures have motivated the need for streamlined solutions for conducting development assurance in support of a system safety assessment process. Additionally, the affected design space for commercial vehicles has been growing beyond the conventional regulatory parts of airplanes, rotorcraft, engines, and propellers, addressed by current guidance. This space is beginning to include commercial technologies such as unmanned aerial systems, multi-stage spacecraft systems, and road-able aircraft. These developing areas are each accompanied with their own development assurance expectations to meet their own safety concepts. At the same time, the industry and regulators are working to simplify standards and guidance for system safety and development assurance, which have existed as staples for decades. From the 14 CFR Part 23 reorganization to the Streamlining Assurance Process Workshops, the existing guidance is under pressure to adjust to new expectations within these technical areas. There are several existing challenges with the current guidance which complicates both its application to these new technical areas and alignment with these streamlining expectations. These challenges include confusion around: its application to programs with new and legacy systems, its interface with regulatory agencies, and its alignment with regulations and other guidance. Meeting these challenges requires shifts from overly prescriptive and complex guidance to ones which provide clear expectations towards planning for, assessing, and achieving objectives that clearly align with regulations. This work seeks to: identify these challenges and expectations in the current environment, understand how the current guidance relates to them, and propose a solution which could meet them. It proposes a single standard concept which will address these issues, while still permitting the continued use of existing guidance.
