Review ACS Recommendations
Assess the recommended update to the Airman Certification Standards for maintenance technicians. The ACS has been incorporated by reference into the rules associated with training and mechanic certification and is valuable for qualifying repairmen; repair stations must be involved in the standards’ construction.
Developed by an industry working group coordinated by the Aviation Technician Education Council (ATEC) , this recommendation incorporates feedback from educators, industry representatives, trade associations, and examiners. The purpose is to modernize the mechanic ACS framework while improving clarity, traceability, evaluator consistency, and workforce readiness. The proposed revision includes:
- Modernized subject organization and system-aligned structure
- Enhanced knowledge, risk management, and skill elements
- Observable performance criteria aligned with competency-based training principles
- Improved integration of human factors and maintenance risk management
- New competency domains intended to support consistent evaluation and workforce readiness
To get the most out of reviewing the proposed revision and to provide actionable feedback:
- Begin with the Companion Guide. This provides the “why” and “how” behind the revision and makes the ACS easier to navigate.
- Review the Draft Mechanic ACS Rev A recommendation in sequence:
- Front Matter: explains major changes and overall intent
- Appendices: includes Performance Standards and Competency Domains
- ACS Content: Subjects have been reorganized for improved flow, color coding identifies revised and new content.
- Evaluate the revision with a fresh perspective. Rather than comparing line-by-line with the current ACS, select a subject area you know well and compare it to your existing curriculum, training materials, or testing processes. This provides the clearest picture of how the proposed structure aligns with real-world training and evaluation practices.
- Submit feedback to ATEC by June 15. Comments may address areas that work well, items needing clarification, and any elements that may appear misaligned with training, testing, or industry expectations.
- Use the feedback form to provide specific feedback or email maguire@atec-amt.org.
