Overview of Part 147 Compliance in Aviation Maintenance Training
Part 147 compliance typically points to either the United States Federal Aviation Administration under 14 CFR Part 147, or the European Union Aviation Safety Agency under Annex IV to Regulation (EU) No 1321/2014. In the U.S., 14 CFR part 147 governs Aviation Maintenance Technician Schools, or AMTS, that prepare students for FAA mechanic certification.
Compliance covers the full training environment: curriculum, facilities, instructor qualifications, equipment, records, quality control, and student outcomes. Training programs must directly prepare students for mechanic licensing exams, aligning with the Mechanic Airman Certification Standards (ACS) as required by the FAA and matching Part 66 licensing guidelines as mandated by EASA.
This differs from Part 65, where a mechanic may qualify through documented experience rather than an approved school. The AMTS route provides a structured process with consistent theory, practical tasks, and assessment. Our role is to help regulated training organizations maintain continuous compliance, document evidence, and avoid findings during FAA inspection activity.
Regulatory Framework and 2022 Part 147 Modernization
The legal foundation is 14 CFR Part 147, enforced by the FAA to govern certification and continuing operation of aviation maintenance technician schools. A school must clear a multi-phase certification process managed by local aviation authorities to establish and maintain Part 147 status.
The certification process includes five phases, starting from pre-application to the issuance of the Air Agency Certificate and operations specifications, ensuring compliance with curriculum and operational requirements. To obtain a certificate to operate an aviation maintenance technician school, an applicant must demonstrate compliance with the requirements outlined in 14 CFR Part 147, including providing a description of facilities, curriculum, and qualified instructors. See the following section for additional curriculum requirements.
The 2022 revision of Part 147 shifted from prescriptive time-based requirements to an outcome-based model, allowing AMTS programs greater flexibility in curriculum design as long as they demonstrate student achievement of defined learning standards. Under the new regulations, the previous fixed hourly minimums for curricula have been removed, allowing schools to focus on competency-based completions while still maintaining training programs of similar duration to meet the technical content depth required by the ACS standards.
Key references to check include:
- §147.17 for training requirements and curriculum concepts
- §147.19 for instructor requirements
- §147.21, under the revised curriculum framework, requiring each AMTS to develop and maintain an FAA-approved curriculum organized around learning objectives tied to Aviation Maintenance Technician Airframe, Powerplant, and General Airmen Certification Standards
- §147.23 for quality control system approval
- §147.25 for minimum passage rate
- §147.29 and related guidance for records
The FAA’s AMTS information and Advisory Circular guidance such as AC 147-3B and current updates help schools interpret the regulation without turning every policy into a legal chapter.
Facilities, Equipment, and Quality Control Requirements
Physical resources matter because aviation maintenance education is hands-on. Each certificated aviation maintenance technician school must maintain facilities, equipment, and materials appropriate to the ratings held and the number of students taught, as specified in 14 CFR Part 147.
Schools must provide climate-controlled classrooms and maintain dynamic instructional workshops containing functional aircraft components, engines, and specialist tools. Student-to-instructor ratios are federally capped, such as a strict 25:1 limit during shop and lab classes according to FAA standards.
A practical facility check should include:
- Classrooms, labs, hangars, lighting, ventilation, and safety systems
- Representative aircraft, engines, components, and testing equipment
- Current technical data, maintenance manuals, regulatory references, and manufacturer publications
- Documented calibration, inspection, and removal of unserviceable tools or training material
Each certificated aviation maintenance technician school must provide and maintain facilities, equipment, and materials that are appropriate to the ratings held by the school and the number of students taught. A certificated aviation maintenance technician school must display its aviation maintenance technician school certificate at a visible location accessible to the public at each school location.
Curriculum Design, Instruction, and Student Assessment
Programs must adopt syllabi that align directly with FAA’s Mechanic Airman Certification Standards (ACS) to ensure necessary theory and practical skills are mastered. That means curriculum design starts with a detailed ACS gap analysis across general, airframe, and powerplant areas.
A strong curriculum should sequence knowledge before application. For example, electrical theory should lead into troubleshooting an electrical fault, and composite structures content should lead into a practical repair exercise. Certification standards should influence lesson planning, assessment rubrics, graduation criteria, and the final test readiness process.
Instructors must hold appropriate A&P certificates, ratings, and relevant experience for the content they teach. Schools should also document instructor competence, continuing professional development, and how each instructor supports standard educational delivery.
Student assessment must measure performance, not just attendance. Written tests, oral questioning, and practical projects should show mastery of ACS elements. The FAA measures a program’s overall educational quality based on student test outcomes rather than arbitrary nationwide norms.
Compliance Management, Audits, and Recordkeeping
Sustained part 147 compliance depends on a documented management system, internal audits, corrective action, and reliable records-not one-time approval. Schools must formalize their oversight framework to ensure standard educational delivery and comply with FAA regulations.
Each certificated aviation maintenance technician school must establish and maintain a quality control system that meets specific requirements and is approved by the Administrator. The quality control system must provide procedures for recordkeeping, assessment, issuing credit, issuing final course grades, attendance, ensuring a sufficient number of instructors, granting graduation documentation, and corrective action for addressing deficiencies.
Each certificated aviation maintenance technician school must allow the Administrator access to inspect its locations to determine compliance with the quality control system requirements. An aviation maintenance technician school must allow the FAA Administrator access to inspect its locations to determine compliance with operational requirements.
Each certificated aviation maintenance technician school must maintain a minimum passage rate of at least 70 percent for students who take an FAA mechanic test within 60 days after graduation. The minimum passage rate is calculated based on the number of students passing any combination of written, oral, or practical tests, with failures on any one test counted as a student failure unless subsequently passed within the 60-day window. If a school’s pass rates fall below acceptable thresholds, it may trigger mandatory curriculum review or, in extreme cases, certificate action by the FAA.
Common surveillance issue areas include outdated syllabi, incomplete student records, missing tool calibration logs, and weak evidence of practical competency. The best prevention is routine internal audit activity, version control, and FAA-ready data with clear date tracking.
