System Safety Assessments

FR Abstract
The FAA is amending certain airworthiness regulations to standardize the criteria for conducting safety assessments for systems, including flight controls and powerplants, installed on transport category airplanes. With this action, the FAA seeks to reduce risk associated with airplane accidents and incidents that have occurred in service, and reduce risk associated with new technology in flight control systems. The intended effect of this rulemaking is to improve aviation safety by making system safety assessment (SSA) certification requirements more comprehensive and consistent.
