Purpose of This Notice.

This Notice supplements Federal Aviation Administration (FAA) Order 8110.4C, Type Certification, and explains FAA interim policy regarding some of the requirements of Section 105(a) of The Aircraft Certification, Safety, and Accountability Act, Pub. L. 116-260 (the Act). Section 105(a) of the Act established paragraph 44704(e) of Title 49, United States Code (49 U.S.C.). The Act mandates that the Administrator require the submittal and disclosure of safety critical information by applicants for, or holders of, new or amended, but not supplemental, type certificates (TC) for transport category airplanes covered under title 14, Code of Federal Regulations (CFR) part 25. Section 105(a) also mandates the FAA to establish multiple milestones throughout the certification process at which a proposed airplane system will be assessed to determine whether any change to such system during the certification process is such that the system should be considered novel or unusual by the Administrator.

The FAA is initiating rulemaking that will propose to mandate, after notice and an opportunity for the public to comment, Section 105(a)'s requirements for transport category airplane new and amended TC applicants and holders. However, this Notice addresses methods of clearly identifying, as "safety critical", certain information that already is, and can continue to be, provided by applicants during the application process for a new or amended TC project for a transport category airplane. The Notice also discusses usage of milestones throughout the project.
