This rulemaking would revise title 14, Code of Federal Regulations (14 CFR) part 23 as a set of performance-based regulations for the design and certification of small transport category aircraft. This rulemaking would: (1) reorganize part 23 into performance-based requirements by removing the detailed design requirements from part 23. The detailed design provisions that would assist applicants in complying with the new performance-based requirements would be identified in means of compliance (MOC) documents to support this effort; (2) promote the adoption of the newly created performance-based airworthiness design standard as an internationally accepted standard by the majority of other civil aviation authorities; (3) realign the part 23 requirements to promote the development of entry-level airplanes similar to those certified under Certification Specification for Very Light Aircraft (CS-VLA); (4) enhance the FAA’s ability to address new technology; (5) increase the general aviation (GA) level of safety provided by new and modified airplanes; (6) amend the stall, stall warning, and spin requirements to reduce fatal accidents and increase crashworthiness by allowing new methods for occupant protection; and (7) address icing conditions that are currently not included in part 23 regulations.
