Federal Aviation Administration, DOT.


Notice of availability; request for comments.


This notice announces a Federal Aviation Administration (FAA) proposed advisory circular that provides a standard compliance checklist for Title 14 of the Code of Federal Regulations (14 CFR) part 23 Type Certificate, Amended Type Certificate, and Supplemental Type Certificate projects. This checklist shows the typical methods of compliance with the regulations and provides a cross-reference to other related guidance material. The checklists created using the information in this AC complement the guidance in the Guides for Certification of Part 23 Airplanes (ACs 23-8B, 23-16A, 23-17B, and 23-19) and other more project specific guidance. This checklist is a starting place when applying for certification. This AC describes an acceptable means, but not the only means, of compliance with 14 CFR part 23. The material in this AC is neither mandatory nor regulatory in nature and does not constitute a regulation.
