Conformity and compliance inspections are required during STC application projects. See the latest revision of FAA Order 8100.4, Type Certification Process. 6-2. CONFORMITY INSPECTIONS. a. Conformity inspections are required to verify that an aircraft component or modification conforms to the data submitted to the FAA, and that the product being certificated complies with the Type design. These inspections physically compare the component or modification to the engineering specifications, drawings, and the airworthiness standards. Conformity inspections are instigated by filling out FAA Form 8110-1, Type Inspection Authorization or FAA Form 8120-10, Request for Conformity, and submitting it to the MIDO through the ACO project engineer. Conformity inspections are recorded and reported on FAA Form 8100-1, and FAA Form 8130-3 is completed if required. See appendix 4 and the latest revision of FAA Order 8110.4. NOTE: An FAA conformity inspection should be successfully conducted before any official FAA tests (ground or flight) are conducted. Conformity inspections are requested by FAA engineering. b. Conformity Inspectors may either be Aviation Safety Inspectors (Manufacturing), or FAA authorized Designated Manufacturing Inspection Representatives (DMIR), and manufac-turing DAR's. FAA manufacturing aviation safety inspectors are located at various MIDO's throughout the certifying directorate. c. FAA Form 8130-9, Statement of Conformity, ensures that parts are manufactured and/or installed to the latest revision of the descriptive data, prior to FAA inspection. The applicant signifies this by signing FAA Form 8130-9 and noting any deviations listed. In addition, for completed products, the applicant is required to certify that the modified aircraft, engine, or propeller is in conformity with the original Type Design, except as affected by the modification being presented for approval and by other previ-ously approved modifications. d. Test articles are built in accordance with engineering data. All components which are to be part of an initial STC modification and require tests, other than flight tests, (such as structural, fuel flow, etc.), require a complete part conformity inspection before the test is started unless prior authorization is obtained to allow a post test conformity inspection. All modifications which require flight testing must have a complete conformity inspection via the TIA, be tagged (FAA Form 8130-3), and have a satisfactory installation conformity before FAA ground or flight tests can be conducted. See FAA Order 8110.4. e. Progressive inspections may be conducted by the manufacturing aviation safety inspector at appropriate intervals during the modification process if coordinated early in the project. 6-3. COMPLIANCE INSPECTIONS. These are required to verify that a particular component or modification to an existing design meets the requirements of the applicable 14 CFR's or CAR's through a combination of specification review and physical inspection of the component, installation, or aircraft. FAA engineering and AEG personnel or an authorized DER arranges and conducts these inspections. See the latest revision of FAA Order 8110.4. 6-4. PARTS MANUFACTURER APPROVAL (PMA) AND PRODUCTION INSPECTIONS. If production parts are to be manufactured prior to obtaining a "multiple" STC, control over all manufactured "production" parts should be maintained by the applicant until FAA approval of the STC and production. Production parts produced prior to PMA approval should not be shipped. Design changes may require additional certification testing. The MIDO will only do conformity inspections on parts required for ground or flight tests required to obtain STC approval. They will not inspect production parts. See Order 8120.9 and Advisory Circular 21-32A. NOTE: MIDO/Manufacturing DAR's may inspect multiple ship sets of parts, some used for the STC and some designated for production, if the parts are required to be shipped to a remote site where the test and production aircraft are being modified. 6-5. TYPE INSPECTION AUTHORIZATION. A TIA specifies installation conformity inspection and
certain ground and required flight tests to be performed by
the FAA or FAA designee. It also requires submittal of FAA
Form 8130-9 stating that the article has been inspected and
corresponds to the design data. The FAA inspector or
designee will then verify conformity. See 6-2.d. above and
chapter 7. |
