AcknowledgmentsThe U.S. Department of Transportation, Federal Aviation Administration (FAA), Airman Testing StandardsBranch, P.O. Box 25082, Oklahoma City, OK 73125, developed this Airman Certification Standards (ACS)document with the assistance of the aviation community. The FAA gratefully acknowledges the valuable supportfrom the many individuals and organizations who contributed their time and expertise to assist in this endeavor.AvailabilityThis ACS is available for download from www.faa.gov. Please send comments regarding this document toAFS630comments@faa.gov.DraftMaterial in FAA-S-ACS-1 will be effective TBD. All previous editions of the Aviation Mechanic General, Airframe,and Powerplant Practical Test Standards (FAA-S-8081-26, -27, and -28) will be obsolete as of this date forAviation Maintenance Technician applicants.i
ForewordThe FAA has published the Aviation Maintenance Technician (AMT) – General, Airframe, Powerplant ACSdocument to communicate the aeronautical knowledge, risk management, and skill standards for AMTcertification. This ACS incorporates and supersedes the previous editions of the following documents: FAA-S-8081-26A, Aviation Mechanic General Practical Test Standards (with Change 1, dated 4/27/15); FAA-S-8081-27A, Aviation Mechanic Airframe Practical Test Standards (with Change 1, dated 4/27/15,and Change 2, dated 9/29/15); FAA-S-8081-28A, Aviation Mechanic Powerplant Practical Test Standards (with Change 1, dated4/27/15); and FAA-G-8082-3A, Aviation Maintenance Technician-General, Airframe, and Powerplant Knowledge TestGuide (dated September 2008).tThe FAA views the ACS as the foundation of its transition to a more integrated and systematic approach toairman certification. The ACS is part of the safety management system (SMS) framework that the FAA uses tomitigate risks associated with airman certification training and testing. Specifically, the ACS, associated guidance,and test question components of the airman certification system are constructed around the four functionalcomponents of an SMS:Safety Policy that defines and describes aeronautical knowledge, risk management and skill as integratedcomponents of the airman certification system; Safety Risk Management processes through which both internal and external stakeholders identifychanges in regulations, safety recommendations, or other factors. These changes are then evaluated todetermine whether they require modification of airman testing and training materials; Safety Assurance processes to ensure the prompt and appropriate incorporation of changes arising fromnew regulations and safety recommendations; and Safety Promotion in the form of ongoing engagement with both external stakeholders (e.g., the aviationmaintenance and training industry) and FAA policy divisions.raf DThe FAA has developed this ACS and its associated guidance in collaboration with a diverse group of aviationtraining experts. The goal is to drive a systematic approach to all components of the airman certification system,including knowledge test question development and conduct of the oral and practical test. The FAA acknowledgesand appreciates the many hours that these aviation experts have contributed toward this goal. This degree ofcollaboration, a hallmark of a robust safety culture, strengthens and enhances aviation safety at every level of theairman certification system.John S.

IntroductionAirman Certification Standards ConceptThe goal of the airman certification process is to ensure the applicant possesses the knowledge, ability to managerisks, and basic skills consistent with the privileges of the certificate or rating being exercised. The AirmanCertification Standards (ACS) concept forms a more comprehensive standard for what an applicant must know,
