3-13. AMTS NORM VS. NATIONAL PASSING NORMS, AC FORM 8080-08, AND ASSOCIATED REPORTS IN THE SERIES. This series of reports provides information to the school and the responsible FAA region and district offices about the test performance of school graduates. The reports are used to monitor school performance and to determine whether schools meet the quality of instruction provisions of § 147.38(a). The reports are posted quarterly (6 weeks after the end of each calendar year quarter) to the publicly accessible FAA Norms Web site at http://www.faa.gov/data_research/aviation_data_statistics/test_statistics/. Two years of norms reports are maintained and available on the Web site. The report data is available to the public and may be shared freely with the school to which it refers as well as any other party.

a. 8080-08 Report. The 8080-08 is the basic report of the series. It contains a record of test activity and performance of graduates of the subject schools who apply for a mechanic written test for the first time within 60 days after graduation.

b. Applicant Listing. Aviation Maintenance Test Applicant Listing contains a record by applicant name of the test performance for graduates from a subject school for a time period specified by the requestor and is produced on request by AFS-630.

c. Non-School Reports. “Non-school” reports are quarterly reports arranged by the region in which the testing occurred. These reports are made for the following:

• Applicants who graduate from a certificated school and who take the mechanic tests for the first time within 60 days of graduation (8080-09);

• Applicants who graduate from a certificated school, but who take the mechanic tests for the first time more than 60 days after graduation (8080-07), and

• Applicants who qualify for testing through actual experience and are not graduates of a certified school (8080-04).

3-14. AVAILABILITY OF TYPE-CERTIFICATED AIRCRAFT. Section 147.17(a)(2) requires an AMTS to provide a type-certificated aircraft for student instruction. Specific requirements are discussed in Chapter 2, par 2-10, Instructional Aids and Aircraft.

Par 4-1 Page 23 CERTIFICATION PROCEDURES CHAPTER 4.

4-1. GENERAL INFORMATION ON CERTIFICATION PROCEDURES.

a. Certification Process. 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 OpSpecs. 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 10, Certification Process Flowchart. Figure 4-1, AMTS Certification Process Guide, provides a certification checklist as an aid to ensure all documents and procedures are complied with and recorded.

b. Five Phases. The FAA certification process consists of the five separate phases listed below:

• Preapplication phase;

• Formal application phase;

• Document compliance phase;

• Demonstration and inspection phase; and

• Certification phase.

NOTE: These phases may often overlap and can proceed concurrently. As an example, the document compliance phase may begin as soon as documents are received, before or during the formal application phase. The AMTS applicant is highly encouraged to review Volume 2, Chapter 12, Section 1 in order to be informed of the guidance the ASI is required to follow to complete the part 147 Air Agency certification process.

4-2. PREAPPLICATION PHASE.

a. Initial Inquiry. An applicant seeking to develop an AMTS for certification must contact the local FAA FSDO and advise the office of the intent to pursue part 147 school certification. The FAA will advise the applicant of the necessity for a preapplication meeting as well as provide the AMTS certification applicant with a blank copy of FAA Form 8400-6, Preapplication Statement of Intent, (see Figures 4-2 and 4-3), and an explanation of where to send the form after completion. The FAA should provide the applicant with information on how to obtain regulatory requirements and guidance associated with acquiring an FAA part 147 certification. Information on additional guidance material associated to the part 147 certification process such as orders and ACs may also be provided to the applicant at this time. The FAA informs the applicant of the necessity to review the regulatory requirements and return the completed Preapplication Statement of Intent (PASI) to the FSDO before a preapplication meeting can be scheduled.

b. PASI. An applicant should submit copies of the PASI only after reviewing the appropriate regulations and advisory materials. Before PASI submission, the applicant should consider the personnel, facility, equipment, and regulatory requirements for certification and operation.

(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 attachments can be presented to the FAA in writing either before or during formal application. The attachment documents needed to be prepared and brought to the formal application meeting and include the following:

(a) A letter of compliance, i.e., statement of compliance (SOC), 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 Schedule of Events (SOE) to be completed for certification with projected due dates.

(c) Standards for graduation.

(d) An attendance policy, a system for recording student attendance, and subject makeup procedures.

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

(f) 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.

(g) Two completed copies of FAA Form 8310-6.

(h) A detailed description of the proposed curriculum. Since 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 2-7.

(i) A written description or diagram of the facility layout 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.

(j) 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 4-2 Page 31

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

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

(k) 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 one 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.

(l) 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.

(m) 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.

(n) 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.

(o) 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, catalog references, and other course documentation may be used to grant credit.

(p) 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.

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

(r) 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.

4-3. 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.

Par 4-3 Page 32

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.

4-4. 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.

4-5. 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.

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

• Facilities must meet the requirements of §§ 147.13 and 147.15;

• Instructional equipment must meet the requirements of § 147.17; and

• All special tools, hand tools, shop equipment, and instructional materials must meet the requirements of § 147.19.
