At the beginning of each product lifecycle is the design phase, which serves to turn an idea into a marketable product. After market introduction, design activities will once again play a role in case of modifications, refurbishment or major repairs. Design activities in the aerospace industry are unique, since they are subject to exceptional control and surveillance by legislation and aviation authorities. Strict requirements for the design of the product as well as for the company organization and staff qualification should ensure that appropriate attention is paid to safety and reliability during design phase.<\/p>\n

Design activities on aeronautical products may only be carried out by EASA approved design organizations. Design organisations in the sense of the EASA are thereby all companies, which develop aeronautical products, parts and appliances, define changes or repair procedures at these. For such activities, organisations must have demonstrated their qualifications to their responsible aviation authority. The requirements for design organisations are defined in the Implementing Rule Initial Airworthiness EASA Part 21 Subpart J (Part 21J for short). Supplementary implementation notes are given by the corresponding AMC and Guidance Material (GM). Regulatory monitoring of design organisations is carried out by EASA or national aviation authorities (NAA).<\/p>\n

As a result, the design organizations provide Applicable Production Data as well as Applicable Maintenance Data. EASA issues Type Certificate and approvals for repair procedures based on the above activities.<\/p>\n

A high level of safety of products must be ensured by a comprehensive quality \/ design assurance system. The basis for an organisation approval according to EASA Part 21J is the fulfillment of the approval requirements specified in 21A.245:<\/p>\n

Prior to initial approval as a Part 21J design organisation, EASA checks the fulfillment of the approval requirements in form of an audit. These are repeated at regular intervals to ensure that the organisation can maintain the approval requirements over time. In these surveillance audits, compliance with aviation legisaltion is checked on a random basis. Both before initial approval and during operation, the risk is usually less that individual approval requirements are not met in their entirety, but that they are not fully met. Common deficits in the fulfillment of approval requirements are:<\/p>\n

Design on aviation products require a complex approval procedure. Before this is not completed, an aircraft may not be allowed to operate, or individual products may not be installed in an aircraft.<\/p>\n
At the beginning of a design process is the preparation of a general description or specification. On this basis, the planned activities should be classified according to their scope and complexity. A distinction is made between the design categories minor and major. Following this classification of the design activity, the certification program (CP) is defined. The CP forms the basis of the typ certification process. 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
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
Onc showing of compliance has been finished and the certification program has been successfully completed, the EASA (Agency) issues the type certificate.<\/p>\n
