Transport Airplane and Propulsion Certification Modernization

Document 2026-12922 is a Proposed Rule published by the Department of Transportation in the Federal Register on June 26, 2026. FAA proposes to amend various airworthiness regulations to modernize certain certification standards for transport category airplanes and propulsion systems. This rule would be both deregulatory and relieving by reducing the number of exemptions, special conditions, and equivalent level of safety findings required during the certification process. FAA expects that this proposal would reduce certification costs and time to certify new and changed products for both industry and FAA while maintaining or increasing the level of safety provided by the current regulations. FAA proposes to remove Special Federal Aviation Regulation (SFAR) No. 109 from part 25 and relocate certain of its requirements. Finally, this action would address industry and National Transportation Safety Board recommendations while also harmonizing FAA's regulations with international standards.
