FAA Accepts ASTM Standards for Part 23 Compliance

On May 11, 2018, the FAA published a "Notification of Availability" with a request for comments.

This notice announced the availability of 63 Means of Compliance (MOC) based on 30 published ASTM International 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. FAA Administrator Daniel K. Elwell finds these MOCs to be an acceptable means, but not the only means, of showing compliance to the applicable regulations in Part 23, amendment 23-64, for normal category airplanes.

The administrator finds these ASTM standards provide at least the same level of safety as the corresponding requirements in Part 23, amendment 23-63. 

The FAA states that pursuant to FAA Advisory Circular 23.2010-1, section 3.1.1, where the FAA committed to notification of their acceptance of standards, this notice serves as a formal acceptance by the administrator, of MOCs based on consensus standards developed by ASTM.

Repair Stations are encouraged to review the "Notification of availability" for the complete information. Comments may be emailed to steven.thompson@faa.gov. Comments must be received on or before July 10, 2018. Specify the MOC, and if applicable, the standard being addressed by designation and title. Mark all comments: Part 23 MOC Comments.
