Certification Maintenance Requirements
This advisory circular (AC) provides guidance on the selection, documentation, and control of Certification Maintenance Requirements (CMR). This AC also provides a rational basis for coordinating the Maintenance Review Board (MRB), if the MRB process is used, and CMR selection processes to ensure premises made in the system safety analyses supporting the compliance with the requirements of Title 14, Code of Federal Regulations (14 CFR) 25.1309, and other system safety rules (such as §§ 25.671, 25.783, 25.901, and 25.933) are protected in service. This AC describes an acceptable means, but not the only means, for selecting, documenting, and managing CMRs. Terms such as "shall" and "must" are used only in the sense of ensuring applicability of this particular means of compliance when the acceptable means of compliance described herein is used.
