CHAPTER 4. CERTIFICATION PROCEDURES

1. GENERAL INFORMATION ON CERTIFICATION PROCEDURES.

a. 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 AMTS certificate. This process ensures the school’s curriculums, programs, policies, facilities, and methods of compliance with the regulations are thoroughly reviewed, evaluated, and validated. A certification schedule flowchart for the AMTS certification process is shown in Appendix 9, Certification Schedule Flowchart. Figure 4-1 provides a certification checklist as an aid to ensure all documents and procedures are complied with and recorded.

c. Preapplication Meeting. Following receipt of the completed PASI, the FAA will contact the AMTS applicant and arrange a preapplication meeting. During this meeting, the applicant should ask any questions that he or she may have concerning FAA certification. The following events take place during the preapplication meeting:

(1) FAA personnel brief the applicant on the regulatory requirements and policies regarding certification and operation of an AMTS.

(2) The applicant informs the FAA as to which of the three types of ratings are sought:

airframe, powerplant, or combined A&P.

NOTE: Because of the complex ity and costs involved in certification, many AMTS applicants init ially choose to seek certifica tion for only one rating to reduce certification time and to get classes under way.

(3) The applicant is given copies of FAA Form 8310-6, Aviation Maintenance Technician School Certificate and Ratings Application, to complete. See Figure 4-4.

(4) The applicant is given a thorough briefing on required attachments to the formal application. The applicant is briefed on how to comply with these requirements, because the quality of these documents is a positive determining factor in FAA certification review.

NOTE: These attach ments can be pres ented to the FAA in w riting either before or during formal application. The attachment documents should include the following:

(a) A document compliance statement listing each applicable part 147 section. The statement should provide either a brief narrative or, preferably, a specific reference to a manual, curriculum, or other document that describes the manner of compliance with each part of that regulation.

(b) A system for recording student attendance and the student attendance policy.

(c) A system providing procedures for maintenance of precision/special tools.

(d) A letter requesting that the application be processed and indicating when the facilities and equipment will be ready for a formal inspection by the FAA.

(e) Two completed copies of Form 8310-6.

(f) A detailed description of the proposed curriculum. Because the curriculum must be approved by the FAA before the school can be certificated, an applicant can save time and money if the proposed curriculum is submitted before the formal application. Typically, a curriculum may take several FAA/AMTS review sessions before approval is granted. See curriculum requirements in Chapter 2, paragraph 2-6.

(g) A written description of the facilities to be used for instruction. The applicant should also provide detailed drawings, with dimensions of the classrooms, the technical library, and laboratory and shop facilities. Drawings should show the relative location of each school’s facilities to each other. If classrooms or laboratories and shops are located at significant distances from each other, the applicant should describe whether and how travel time will affect required class attendance time.

(h) A proposed inventory of the following items:

• Instructional aids that include the numbers and types of mockups, aircraft, aircraft components, charts, or other visual instruction tools

• All shop equipment

• All special tools

Par 2 Page 7

• Required student handtools (the applicant must list in detail which handtools will be provided by the school and which tools the student will be required to provide)

• Laboratory and shop instructional materials (for example, rivets and sheet metal)

(i) A list of proposed instructors indicating all required certificate number(s) and rating(s), and the subjects to be taught by each instructor. Every subject in the proposed curriculum must be accounted for on the instructor listing. At least 1 FAA-approved instructor is required for every 25 students in each laboratory and shop class. This requirement must be reflected in the list of instructors.

(j) A statement indicating the maximum number of students to be taught for each rating during each enrollment period. This information must be shown on the application form as well.

(k) A written description of the contents and location of the proposed technical data reference area, including the appropriate and current technical data necessary for the ratings sought. The description should contain procedures on how, when, and by whom the technical data will be updated.

(l) A written description of the method the school will use to grant credit to students with previous AMT experience. Section 147.31(c)(3) requires that only documentary evidence and testing may be used to grant credit for experience. Previous experience must be aviation maintenance experience and must be comparable to the required curriculum subjects.

(m) A written description of the method the school will use to grant credit to students for previous AMT training. Section 147.31(c)(1) permits several methods to be used for granting credit for previous training. School transcripts, catalogs, and other course documentation may be used to grant credit.

(n) If it is not specifically included in the curriculum, a written description of the method the school will use to record and maintain student time, attendance, and course grades.

The system must include a method of determining final course grades, which are a combination of classroom, laboratory, and practical project grades. All required practical projects must be completed to at least the minimum grading standards.

(o) A system that indicates how testing and grading security will be maintained

(p) A listing of any texts that will be used in the approved curriculum. These must be appropriate to the instructional material, curriculum, and the FAA ratings sought.

3. FORMAL APPLICATION PHASE.

a. Document Review. After the AMTS submits the required PASI and preapplication information to the FAA, the FSDO will review the documents. When the FSDO has determined that all the documents are complete and acceptable, the FSDO will contact the school and arrange for a formal application meeting.

b. The Formal Meeting. In the formal application meeting, the AMTS applicant’s key decision-making personnel should be available to meet with the FAA and discuss the entire application package. Any open questions or discrepancies should be resolved at this time.

Based on the document review and the results of these meetings, the FAA will accept or reject the application at that time. The FAA will document the results of the meeting in writing. In the case of a rejected application, the FAA will return the application and attachments to the applicant with the reasons stated for rejection.

4. DOCUMENT COMPLIANCE PHASE. This phase generally overlaps the preapplication phase and extends through the formal application phase. It is recommended that this phase be initiated as early as possible in the certification process.

a. Evaluation of Documentation. The FAA will carefully review all documents submitted during the preapplication phase. The FAA can be expected to place particular emphasis on the curriculum content and the methods within the curriculum used to comply with the regulations.

The FAA will maintain contact with the applicant during this phase. If deficiencies are found in the curriculum or in any other preapplication documents, the FAA will return these documents to the applicant with a letter outlining the deficient areas. The FAA generally offers suggestions on modifying the product, but will not write the applicant’s documents. A future meeting between the FAA and the applicant will be scheduled to discuss each deficiency in detail. If the documents, as a whole, are not of sufficient quality to complete the certification, the FAA will terminate the entire certification process.

b. Termination. In the case of termination of the certification process, the applicant must submit a new PASI to begin the certification process again.

5. DEMONSTRATION AND INSPECTION PHASE.

a. Inspection Schedule. Following a successful formal application phase, the FAA will arrange with the applicant to inspect the facility. At this point, the FAA expects the AMTS facility to be complete with all the shop equipment, instructional aids, instructional aircraft, special tools, and other required laboratory or shop installations in place. Before scheduling an inspection, the applicant should be certain the facility is ready to meet the standards.

b. Emphasis. During the inspection, the FAA inspectors will carefully examine the facilities and equipment to ensure that procedures, programs, facilities, and equipment meet FAA requirements and are safe and sufficient for the training program in the shop to be effective.

Par 3 Page 9

c. Demonstration Criteria. In particular, the AMTS must demonstrate compliance with the following regulations:

(1) Facilities must meet the requirements of part 147, sections 147.13 and 147.15.

(2) Instructional equipment must meet the requirements of section 147.17.

(3) All special tools, handtools, shop equipment, and instructional materials must meet the requirements of section 147.19.

d. Demonstration Deficiencies. When deficiencies in the demonstration arise, the FAA will provide a written list of the discrepancies to the applicant. Depending on the magnitude of the deficiencies, the FAA may schedule a meeting to discuss in detail the appropriate corrective actions that must be taken. At or immediately following the meeting, the applicant must provide the FAA with a list of all corrective actions taken. No AMTS will be FAA-certificated with outstanding discrepancies. All discrepancies must be corrected before certification may be granted. If the discrepancies cannot be resolved and/or the applicant does not demonstrate compliance with the regulations, the FAA will terminate the certification process and send the applicant a letter of rejection and a list of the discrepancies still outstanding.

e. Termination. If the FAA terminates the application, the applicant must correct the discrepancies and submit a new PASI to reinitiate the certification process.

6. CERTIFICATION PHASE.

a. Successful Application. When all the regulatory requirements have been met, the school will be issued an AMTS certificate. The form will contain the name of the school and its ratings.

At this time, the school’s curriculum will be returned by the FAA, signed, and dated on all the effective pages and on any revision pages.

b. Surveillance. A newly certificated school should expect that the FAA will inspect and observe the school frequently during the first 90 days of operation to determine compliance with the applicable regulations. The FAA may also identify needed changes in the methods or techniques of the school’s operation.
