Federal Aviation Administration June 4, 2015 – Federal Register Recent Federal Regulation Documents

The FAA assigned the Aviation Rulemaking Advisory Committee (ARAC) a new task to provide recommendations regarding the incorporation of airframe-level crashworthiness and ditching standards into Title 14, Code of Federal Regulations (14 CFR) part 25 and development of associated advisory material. The issue is during the development of current airworthiness standards and regulatory guidance, the FAA assumed that airframe structure for transport airplanes would be constructed predominantly of metal, using skin-stringer-frame architecture. Therefore, certain requirements either do not address all of the issues associated with nonmetallic materials, or have criteria that are based on experience with traditionally-configured large metallic airplanes. With respect to crashworthiness, there is no airframe-level standard for crashworthiness. Many of the factors that influence airframe performance under crash conditions on terrain also influence airframe performance under ditching conditions. Past studies and investigations have included recommendations for review of certain regulatory requirements and guidance material to identify opportunities for improving survivability during a ditching event; consideration of these recommendations is included in this tasking. This notice informs the public of the new ARAC activity and solicits membership for the Transport Airplane Crashworthiness and Ditching Working Group.
