Design activities in the aerospace industry are unique, since they are subject to exceptional control and surveillance by legislation and aviation authorities.

The requirements for design organisations are defined in the Implementing Rule Initial Airworthiness EASA Part 21 Subpart J (Part 21J for short).

In a first step, the applicable Certification Specifications must be identified. The applicability of a Certification Specifications and its showing of compliance (for example by means of tests or calculations) for the individual case is not always clear, so that it needs interpretation.<\/p>\n<p>The following process step, the showing of compliance, is to examine and justify correspondence of the design with the identified Certification Specifications. EASA checks every major design project during the verification of compliance with the Certification Specifications, regardless of whether it is a completely new aircraft or just a modification.<\/p>\n<p>Onc showing of compliance has been finished and the certification program has been successfully completed, the EASA (Agency) issues the type certificate.<\/p>\n<p>[\/et_pb_text][et_pb_divider show_divider=&#8221;off&#8221; _builder_version=&#8221;4.9.4&#8243; _module_preset=&#8221;e1fbf107-ca39-4ee4-b671-ebf4d2633462&#8243; global_colors_info=&#8221;{}&#8221; theme_builder_area=&#8221;post_content&#8221;][\/et_pb_divider][et_pb_image src=&#8221;https:\/\/aeroimpulse.de\/wp-content\/uploads\/2021\/07\/easa-part-21j-certification-process.jpg&#8221; alt=&#8221;EASA Part 21j Certification process &#8211; design organisations&#8221; title_text=&#8221;easa-part-21j-certification-process&#8221; _builder_version=&#8221;4.9.4&#8243; _module_preset=&#8221;99e9cc5c-e207-4926-bbd9-0e3410aef98a&#8221; global_colors_info=&#8221;{}&#8221; theme_builder_area=&#8221;post_content&#8221;][\/et_pb_image][et_pb_divider show_divider=&#8221;off&#8221; _builder_version=&#8221;4.9.4&#8243; _module_preset=&#8221;e1fbf107-ca39-4ee4-b671-ebf4d2633462&#8243; global_colors_info=&#8221;{}&#8221; theme_builder_area=&#8221;post_content&#8221;][\/et_pb_divider][et_pb_cta title=&#8221;Do you need assistance with component approval?&#8221; button_url=&#8221;https:\/\/aeroimpulse.de\/en\/contact\/&#8221; button_text=&#8221;Contact form&#8221; _builder_version=&#8221;4.9.4&#8243; _module_preset=&#8221;b2ab463a-fbaa-439c-b9ee-1e3ac6f1fafa&#8221; global_colors_info=&#8221;{%22gcid-a4d4b690-c5d0-4305-acd7-d33639818f8a%22:%91%22button_text_color%22,%22button_bg_color__hover%22,%22button_border_color__hover%22,%22body_text_color%22%93,%22gcid-7017af99-804f-4997-adc0-e93f5909dcff%22:%91%22button_text_color__hover%22,%22button_border_color%22%93,%22gcid-447063c4-da45-48e1-96cb-01977443b517%22:%91%22button_bg_color%22%93}&#8221; button_bg_color__hover=&#8221;#ffffff&#8221; button_border_color__hover=&#8221;#ffffff&#8221; button_text_color__hover=&#8221;#151d45&#8243; theme_builder_area=&#8221;post_content&#8221;]<\/p>\n<p>We support you!<br \/>Get a non-binding quote at <a class=\"phone-mail is-white is-underlined is-medium\" href=\"mailto:info@aeroimpulse.de\">info@aeroimpulse.de<\/a> or<br \/><a class=\"phone-mail is-large is-white\" href=\"tel:+494051315291\">+49 (0)40 5131 5291<\/a><\/p>\n<p>[\/et_pb_cta][et_pb_divider show_divider=&#8221;off&#8221; _builder_version=&#8221;4.9.4&#8243; _module_preset=&#8221;e1fbf107-ca39-4ee4-b671-ebf4d2633462&#8243; global_colors_info=&#8221;{}&#8221; theme_builder_area=&#8221;post_content&#8221;][\/et_pb_divider][et_pb_blurb title=&#8221; Certification Specification (CS)&#8221; use_icon=&#8221;on&#8221; font_icon=&#8221;&#x70;||divi||400&#8243; _builder_version=&#8221;4.13.0&#8243; _module_preset=&#8221;70416eee-0fe3-436d-911a-45d7319a9039&#8243; global_colors_info=&#8221;{}&#8221; theme_builder_area=&#8221;post_content&#8221;]<\/p>\n<p>Certification Specifications (CS) Certification Specifications contain detailed requirements for the approval of aeronautical products on a technical level. These CS specify the future design of products while also defining how its airworthiness is demonstrated. While EASA\u2019s Certification Specifications are referred to as <strong>Certification Specification (CS)<\/strong>, US Federal Aviation Administration (FAA) refers to as <strong>Federal Aviation Regulations (FAR)<\/strong>.<\/p>\n<p>The Certification Specifications of EASA and FAA are similar in structure and also often in its content. In principle, however, divergent terminology used for the interpretation material must be taken into account. EASA refers to this as <strong>Acceptable Means of Compliance (AMC)<\/strong>, while the JAR refers to <strong>Advisory Circular Joint (ACJ)<\/strong> and Advisory Material Joint (AMJ).

This is a standard for selected parts &amp; appliances used in civil aircraft. This specifies minimum requirements for the performance level or characteristic of the affected products, which are defined in associated Certification Specifications (CS-ETSO). Typical components subject to the ETSO standard are e.g. Instruments, Seats, Tires, Rescue and Safety Equipment and APUs.<\/p>\n<p>The procedure for design, approval and production of ETSO products is regulated in EASA Part 21 Subpart O. Thereafter, an ETSO approval can be applied by any company that demonstrates the necessary design practice and resources for the product. Thus, an EASA Part 21J design organisation approval is not required to apply for an ETSO design.<\/p>\n<p>Prerequisite for a specific product approval by EASA is the submission of comprehensive information regarding design and performance characteristics (DDP \u2013 Declaration of Design and Performance).<\/p>\n<p>Would you like to learn more about the <span style=\"text-decoration: underline;\"><a href=\"https:\/\/aeroimpulse.de\/en\/etso-components-certification-approval\/\" target=\"_blank\" rel=\"noopener noreferrer\">approval of ETSO products<\/a><\/span>?<\/p>\n<p>[\/et_pb_blurb][\/et_pb_column][et_pb_column type=&#8221;1_3&#8243;
