13、ganisations managing and/or performing design activities and associated tasks (e.g. tests) on behalf of organisation holding a Part 21 DOA (DOAH); share and take benefit of best practices among European Aerospace and Defence Industry. This European standard is focusing on the clauses and processes l
14、inked to the acceptance of Suppliers design capabilities and management of design organisation authorisations to subcontractors and design work-sharing partners. NOTE 1 The assessment of the suppliers capabilities might have been already performed or not by the DOA Holder and/or applicant. NOTE 2 Su
15、bcontractors or design work-sharing partners of the DOA holders or design approval holder, as intended in Part 21.A.239(c), are referred to as “design suppliers” or generically as “suppliers” in the remaining part of this standard, see also clause 3 for terms definition. Reminder: Per 21.A.239 Desig
16、n assurance system (c) The design organisation shall specify the manner in which the design assurance system accounts for the acceptability of the parts or appliances designed or the tasks performed by partners or subcontractors according to methods which are the subject of written procedures. And,
17、per 21.A.243 Data (b) Where any parts or appliances or any changes to the products are designed by partner organisations or subcontractors, the handbook shall include a statement of how the design organisation is able to give, for all parts and appliances, the assurance of compliance required by poi
18、nt 21.A.239(b), and shall contain, directly or by cross-reference, descriptions and information on the design activities and organisation of those partners or subcontractors, as necessary to establish this statement. prEN 9255:2018 (E) 4 1 Scope 1.1 Deliverables and tasks The purpose of this DOA sta
19、ndard is to define generic requirements and methods for the acceptance of suppliers design capabilities and management of Design Organisation authorisations to suppliers performing design activities and/or tasks on behalf of DOAH. This European standard covers all suppliers as soon as they produce d
20、eliverables related to the design of parts or appliances (e.g. design data, compliance documents for certification activities, etc.) and/or perform the associated tasks (e.g. classification of changes to TC, execution of laboratory tests for development or compliance demonstration and associated tes
21、t data results collection and documentation). Any designing of parts or appliances or any execution of associated tasks performed by persons not directly employed by the DOAH should be considered as work being subcontracted, and therefore could be eligible to the cascade of authorisation as defined
22、in this European standard (refer to Table 1 in 1.2). Examples of tasks which can be subcontracted are: laboratory testing, test set-up and/or inspection; design data and drawings; stress analysis; qualification of software/equipment; instructions for continued airworthiness. Examples of tasks which
23、can be delegated are: technical endorsement of laboratory testing, test set-up and/or inspection; technical endorsement of design data and drawings; technical endorsement of stress analysis; technical endorsement of qualification of software/equipment; classification of changes and approval of minor
24、 changes at product level; classification of repairs and approval of minor repairs at product level; technical endorsement of Instructions for continued airworthiness. This European standard is applicable for: initial design during product development (type certificate/STC/RTC process): subcontracto
25、rs contribution to the preparation of compliance documents to be used by TC/STC applicant in the frame of the certification activities; changes to the type certificate/STC/RTC; repairs; engineering decision over unintentional manufacturing deviations. prEN 9255:2018 (E) 5 1.2 Signature rules 1.2.1 G
26、eneral Deliverables to be produced by a supplier might require up to three levels of signatures. 1.2.2 Level 1 Signature This is a signature for technical endorsement of the deliverable (e.g. design data might require only a Level 1 signature, when not used as compliance documents as intended in Par
27、t 21), see 4.1 for more details. 1.2.3 Level 2 Signature This is the signature by a compliance verification engineer, as defined in Part 21.A.239(b) (e.g. a compliance document requires at least a Level 1 and a Level 2 signatures), see 4.2 for more details. NOTE Per AMC 21.A.239(b)(1) The independen
28、t checking function of the demonstration of compliance should consist of the verification by a person not creating the compliance data. Such person may work in conjunction with the individuals who prepare compliance data. 1.2.4 Level 3 Signature This is a signature by an authorised signatory of a DO
29、AH for the exercise of its Part 21.A.263 privileges (e.g. classification of changes to TC, approval of minor changes to TC), see 4.3 for more details. Three levels of signature authorisations can be granted by the DOA holder to its suppliers. The granting of signatory authorisations to suppliers doe
30、s not relieve the DOAH of its DOA obligations as per Part 21 requirements. The Table 1 below provides a synthesis of the scope covered by this standard with the associated deliverable/signatory level. Table 1 Deliverable scope versus applicable signatory level Deliverables are non-product related De
31、liverables are product relatedaLevel 1 DesignbLevel 2 Independent Check Level 3 Release N/A Preparation Validation Acceptance Verification Airworthiness release The activity is not relevant for this European standard. The activity is relevant for this European standard. aThe use of this standard has
32、 been developed for deliverables directly linked to aeroplanes and rotorcrafts, engine or propeller certification without any credit from ETSO/TSO approval if any. This standard needs to be adapted if credit from ETSO/TSO approval is sought. bThe number of required signatures and the associated allo
33、cation of responsibilities within Level 1 are defined by the DOAH applicable procedure and associated deliverable template. prEN 9255:2018 (E) 6 A Level 1 signature authorisation is a an authorisation to a supplier to sign a deliverable requiring at least a Level 1 signature, Level 2 and Level 3 sig
34、nature authorisations are for the signature of a deliverable requiring Level 2 and/or Level 3 signatures. Level 2 authorisation implies a Level 1 authorisation has been already granted. NOTE External CVE acting on behalf of the DOAH and not pertaining to DOAH or Suppliers organisation is allowed but
35、 not covered by the general rules of the current version of the standard. A Level 3 authorisation implies that: a Level 2 authorisation has been already granted, except when authorised scope covers only deliverables without additional work to demonstrate compliance; a Level 1 authorisation has been
36、already granted. The minimum requirements being: one signature for each applicable level; independence is needed between the individual holding a Level 1 signature used to demonstrate the compliance and the individual holding the Level 2 signature performing the verification of the demonstration of
37、compliance. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced documen

When there is a conflict between this European Standard and any other normative reference (with the exception of European law), the present European Standard, developed to support compliance to European aviation safety regulation, prevails except when the suppli
39、er elects to comply with more restrictive/stringent requirements.
