# TYPE CERTIFICATION ## Course Objective Participants will be able to: - Know what type design and type certificate is. - Know the requirements to comply for a type design be given a type certificate. - Know who do the application, design and approval of Aircraft, engines, and propellers. - Identify type certifications when it comes to the parts, componants, appliances; imported products or repair involving design. ## Course outline - **A. Type Certification of Aircraft, Engines, and Propellers** - **B. Parts and Appliances Approval** - **C. Type Certification of Imported Products** ## A. Type Certification of Aircraft, Engines, and Propellers ### What is a TYPE CERTIFICATE? The type certificate is a document by which the authority states that an applicant has demonstrated the compliance of a type design to all applicable requirements. ### The type design of a product - Must be adequately identified according to EASA Part 21 and FAR Part 21, consists of the followings: - The drawings and specifications, and a listing of those drawings and specifications. They are necessary to define the configuration and the design feature of the product shown to comply with the applicable type certification basis and environmental protection requirements. - Information on materials and processes and on methods of manufacture and assembly of the product needed to ensure the conformity of the product. - An approved Airworthiness Limitations section of the instructions for continued airworthiness as defined by the applicable airworthiness code. - Any other data necessary to allow, by comparison, the determination of the airworthiness, the noise characteristics, fuel venting, and exhaust emission (where applicable) of later products of the same type. > In other words, the type design “freezes” not only the product configuration but also the production methods. Every deviation from the type design becomes a “change” which must be approved. > This is to make sure that the series products are not inferior to the prototype identified by the type design, in terms of flight safety. ### The Design Organization - The “person" defined as the applicant becoming the Type Certificate Holder (TCH) once the Type Certificate is issued. - Design organizations must hold (or have applied for) an appropriate DESIGN ORGANIZATION APPROVAL (DOA) under part 21. ### The Type Certificate Data Sheet (TCDS) - The TCDS, which is part of the TC, provides a concise definition of the configuration of a type-certificated product. - The Type Certificate Data Sheet includes general information about the design such as dimensions, wing loading, limiting airspeeds and required placards and markings, control surface travel, engine installations and, where applicable, approved engine/propeller combinations. In practice, the 'datasheet' is more likely to be a lengthy document or an electric file. ## The Supplemental Type Certificate (STC) - Any person who alters a product by introducing a MAJOR change, not sufficient to require a new application for a type certificate, shall apply to the authority for an STC. ### Example Supplemental Type Certificate (STC) application: - A design organization (other than the TCH) can design an agricultural system for crop spraying to be installed on a type-certificated aircraft - A passenger transport airplane can be transformed into a cargo airplane. ## B. Parts and Appliances Approval - All parts and appliances installed on certificated products (aircraft, engines, and propellers) must be approved. ## According to Subpart K of JAR/FAR/EASA Part 21, compliance with applicable requirements may only be made: 1. Where applicable, under the JTSO/TSO/ETSO authorization procedures of Subpart O of JAR/FAR 21/EASA Part 21 or 2. In conjunction with the type-certification procedures for the product (or its change) in which it is to be installed or 3. In the case of Standard Parts, in accordance with officially recognized standards or 4. Where applicable (and JAA certifications) under the Joint Part Approval authorizations (JPA auth.) procedures of Subpart P of JAR 21 or 5. Where applicable (and FAA certification) under the Parts Manufacturer Approval (PMA) issued under FAR 21.303 or 6. According to FAR 21.303(a)(2), "Parts produced by an owner or operator for maintaining or altering his own product" 7. In any other manner approved by the Administrator (the FAA). ## C. TYPE CERTIFICATION OF IMPORTED PRODUCTS - The certification of an imported product is normally carried out through the assessment of the type certification performed in the exporting state, made by the authority of the importing state. - The aim of this assessment is to ensure that the imported product meets a level of safety equivalent to that provided by the applicable laws, regulations, and requirements that would be effective for a similar product in the importing state. ## Bilateral Agreements - To simplify the TC validation processes, bilateral agreements have been made between states; - These agreements are based on a high degree of mutual confidence in the technical competence and regulatory capacity of the exporting authority for performing aircraft certification functions within the scope of the agreement. > the importing state shall give the same validity to the certification made by the competent aeronautical authority of the exporting state as if the certification had been made by its (the importing country's) own competent aeronautical authority in accordance with its own applicable laws, regulations, and requirements. ## Thanks!
