AMC1 21L.A.66(e)(2) Demonstration of compliance ED Decision 2023/013/R TESTS AND INSPECTIONS The applicant should inform EASA sufficiently in advance about the execution of tests and inspections that: — are used for compliance-demonstration purposes; and — have been identified as being of particular interest to EASA during the review and approval of the compliance-demonstration plan in order to permit EASA the opportunity to witness or carry out these inspections or tests. The applicant may propose to EASA to witness or carry out flight or other tests of particular aspects of the product during its development and before the type design is fully defined. However, in case of flight tests, the applicant should perform the tests before EASA witnesses or performs them to ensure that no feature of the product precludes the safe conduct of the evaluation requested. EASA may require any such tests to be repeated once the type design is fully defined to ensure that subsequent changes have not adversely affected the conclusions from any earlier evaluation. A verification document as per point [21L.A.66](#_DxCrossRefBm1649097887)(c) is required for the above tests. ##### AMC1 21L.A.66(e)(2) Demonstration of compliance *ED Decision 2023/013/R* **TESTS AND INSPECTIONS** The applicant should inform EASA sufficiently in advance about the execution of tests and inspections that: — are used for compliance-demonstration purposes; and — have been identified as being of particular interest to EASA during the review and approval of the compliance-demonstration plan in order to permit EASA the opportunity to witness or carry out these inspections or tests.
