Aviation Mechanic Airman Certification Standards
This ACS-1 becomes effective in September 2022 along with the new Part 147 rule, and will be the reference for the FAA Aviation Mechanic Knowledge and Oral & Practical Tests beginning July 2023. The FAA AMT Practical Test Standards (ASA-8081-AMT-4) remain available for sale and in effect until June 30, 2023. AMT schools modifying or adding curriculum should use the ASA-ACS-1, effective September 2022. Applicants should check with their school and instructor to determine which standards they should use—the new ACS-1 or PTS (ASA-8081-AMT-4)—based on their intended O&P test date.
