1.1 The primary purpose of this guide is to address the fundamental subject knowledge, task performance, and task knowledge activities, labeled ‘Core Competencies,’ that ensures the Aircraft Maintenance Technician/Maintenance Engineer (AMT/AME) have the necessary basic knowledge and skills for today’s global aviation maintenance environment. Thus, the ASTM F46 Aerospace Personnel Committee has developed academic and skills knowledge standards that have been developed by aerospace industry-lead working groups. These standards reflect industry best practices and provide a focus on levels of safety that may exceed current regulatory guidance for aircraft maintenance technician academic and skills standards. This guide may supplement a state’s basic general requirements for AMT/AME certification. It is not the intent of this guide to replace the basic or general requirements, but to ensure the AMT/AME is trained on these core competencies to the level as indicated. This guide may be used as a basis for an approval when specifically identified as such by the appropriate governing authority. Parts of this guide may also be referenced by other aerospace personnel groups seeking training, educational, qualification, or certification standards. (See Guide F3245; 14 CFR Part 147; EASA Annex IV, Part 147; NFPA 407; OSHA The Globally Harmonized System for Hazard Communication.)

1.2 An applicant intending to propose this guide as a Means of Compliance for the AMT/AME who works on unmanned aircraft systems (UAS) must seek guidance from their respective oversight authority (that is, published guidance from applicable CAA’s) concerting the acceptable use and application thereof. For information on unmanned aircraft systems, refer to ASTM Committee F38 at www.astm.org/COMMITTEE/F38.htm.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
