Interpretation of Airworthiness Certification Regulations and Research on Means of Compliance for Aircraft Lithium-ion Battery

Abstract

With the best comprehensive performance, Li-ion batteries are widely applied to civil aviation. As the research of its technical characteristics and security risks are defective, and the applicable airworthiness regulations are short of safety standards, foreign administrator issued special conditions, which containing the additional safety standards. Nevertheless, the investigation report of Li-ion batteries fire in aircraft showed that the validation and certification of Li-ion batteries were defective, and the update of standards fell behind the development of Lithium-ion batteries. The risk of Li-ion batteries as an aviation power is analyzed, the existing regulations and special conditions are interpreted, and suggestions for airworthiness means of compliance are provided. Combined with experiences of service and verification, these suggestions will supplement airworthiness means of compliance, improve the verification standard system, and explore the autonomous foundation of standards.
