scope:

The purpose of this DOA standard is to define generic requirements applicable to repair design management and approval.

It provides common means of compliance to EASA Part 21 DOA applicable requirements and/or military equivalent applicable requirements (e.g.: EMAR 21) in:

- identifying the applicable DOA regulatory requirements;

- identifying necessary capabilities and providing guidance for assessment and surveillance;

- describing the end to end repair design management and approval process, from the initiation of the repair design request to the repair design preparation, justification, approval and transmission;

- addressing the DOA requirements for each step of the process.

It is applicable to repairs (4.6) to in service products, parts and appliances, including generic repairs in manuals (4.8).

It should be complemented as necessary by the DOA holder and/or by the design supplier in order to add more detailed process steps used and/or explain deviations, to achieve a repair design management and approval process acceptable to both DOA holder and supplier.

NOTE 1 Repairs of ETSO parts except APU are not covered by this DOA standard because they are out of the scope of Part/EMAR 21 subpart M. They shall be processed according to Part/EMAR 21 paragraph 21A.431A (e).

NOTE 2 The process for cascade of privileges is covered by ASD DOA standard prEN 9255 "Management and Cascading of Design Organisation Authority & Signatory to Supplier"

NOTE 3 The process for Design Assurance monitoring of the repair deliverables is described in the ASD DOA standard prEN 9253 "Surveillance of Design Suppliers".
