Aircraft Maintenance Technician Schools (AMTS)

The FAA Flight Standards Service (FS) is making key improvements to application processing by combining elements of the certification process.

Effective January 24, 2024, FS is utilizing a new process to increase applicant readiness for initial certifications, which is applicable to applicants for an air carrier, air operator, or air agency certificate, or the issuance of management specifications (MSpec) in accordance with Title 14 of the Code of Federal Regulations (14 CFR) parts 91 subpart K (part 91K), 125, 133, 135, 137, 141, 142, 145 (Domestic), and 147.

This new process is a continuation of our efforts to enhance the certification process. FS is committed to designing long term, sustainable improvements that reduce certification wait times and improve application processing times. Please see FAA Notice 8900.687 for further information.

An AMTS is an educational facility certificated by the FAA, under 14 CFR part 147, to train students in the knowledge and skills required for careers in the aviation maintenance industry. When all other eligibility requirements are met, an authenticated document issued by a part 147 AMTS can be used by a mechanic applicant to show eligibility to test for a mechanic certificate airframe and/or powerplant rating, as applicable to the curriculum from which the applicant graduated/completed. The goal of any AMTS should be to prepare students with the basic knowledge, skills, and attitude to be successful in an aviation maintenance career.

An AMTS may be FAA-certificated for the following ratings:


The ratings issued to an AMTS indicate what curriculum(s) the school is authorized to deliver, and subsequently issue a certificate of completion for. An AMTS may only issue a certificate of completion upon a student’s graduation from a specific curriculum, consistent with the schools ratings. The general portion of a curriculum is not a rating, but must be completed as a required part of any rating, pursuant to regulation.
A certificated AMTS is issued an Air Agency certificate as well as Operations Specifications (OpSpecs) which are legal documents by which FAA authorizes the AMTS to operate and describes the schools’ operational requirements, conditions, and limitations. Each authorizing document forms a legal contract between FAA and the certificate holder.

The AMTS certification process is an interaction between the AMTS applicant and the FAA. The certification process extends from the initial inquiry by the school applicant to the final issuance of the Air Agency Certificate and operations specifications (OpSpecs). This process ensures the school’s method of compliance with curriculum, policies and procedures, facilities, equipment, materials, and personnel regulatory requirements are thoroughly reviewed, evaluated, and validated. Any questions about this process should be directed to the nearest Flight Standards District Office (FSDO).


There are 5 phases in the certification process, beginning with pre-application and ending with certificate issuance. Advisory Circular (AC) 147-3C and the applicable FAA Order 8900.1 guidance in the FAA’s Dynamic Regulatory System (DRS) contain detailed descriptions of the applicant requirements in each phase. The certification process flowchart included below provides an overview of the part 147 certification process.
