This document announces the availability of 63 Means of Compliance (MOC) based on 30 published ASTM International (ASTM) consensus standards developed by ASTM Committee F44 on General Aviation Aircraft. A total of 46 of these accepted MOCs consist of ASTM consensus standards as published, with the remaining 17 MOCs comprised of a combination of ASTM standards and FAA changes.

The Administrator further finds that these accepted means of complying with part 23, amendment 23-64, provide at least the same level of safety as the corresponding requirements in part 23, amendment 23-63.
