GM1 21L.A.227(f) Compliance activities for declaring compliance of a major repair design ED Decision 2023/013/R TESTS AND INSPECTIONS PERFORMED BY THE AGENCY The declarant should inform EASA sufficiently in advance about the execution of significant inspections and tests that are used for compliance-demonstration purposes in order to permit EASA the opportunity to perform or witness these inspections or tests in advance of any physical inspection and assessment of the repaired aircraft if required by point [21L.B.221](#_DxCrossRefBm1649098132)(b). This would be advantageous for the declarant to avoid any issues or delays if a physical inspection and assessment of the repaired product is required. Additionally, the declarant may propose to EASA to perform or witness flight or other tests of particular aspects of the product during its development and before the design of the major repair is fully defined. However, before EASA performs or witnesses any flight test, the declarant should perform these tests and should ensure that no features of the product preclude the safe conduct of the evaluation requested. A recorded justification of the conformity of the test articles and equipment as per point [21L.A.226](#_DxCrossRefBm1649097963)(d)(6) is required for the above tests. ##### GM1 21L.A.227(f) Compliance activities for declaring compliance of a major repair design *ED Decision 2023/013/R* **TESTS AND INSPECTIONS PERFORMED BY THE AGENCY** The declarant should inform EASA sufficiently in advance about the execution of significant inspections and tests that are used for compliance-demonstration purposes in order to permit EASA the opportunity to perform or witness these inspections or tests in advance of any physical inspection and assessment of the repaired aircraft if required by point [21L.B.221](#_DxCrossRefBm485231629)(b).
