GM 21.A.20(d) Final statement ED Decision 2019/018/R All compliance demonstrations in accordance with the certification programme, including all the inspections and tests in accordance with point [21.A.33](#_DxCrossRefBm1649096983) and all flight tests in accordance with point [21.A.35](#_DxCrossRefBm1649096994), should be completed before the issuance of the final statement of compliance required by point [21.A.20](#_DxCrossRefBm1649096852)(d). If so agreed by EASA, some compliance documentation may be produced after the issuance of the final statement of compliance required by [21.A.20](#_DxCrossRefBm1649096852)(d). ‘No feature or characteristics’ in point [21.A.20](#_DxCrossRefBm1649096852)(d)2 means the following: while every effort is made to address in the applicable certification basis all the risks to product safety or to the environment that may be caused by the product, experience shows that safety-related events may occur with products in service, even though compliance with the certification basis is fully demonstrated. One of the reasons may be that some existing risks are not properly addressed in the certification basis. Therefore, the applicant has to declare that they have not identified any such features or characteristics. Point [21.A.20](#_DxCrossRefBm1649096852) also applies by reference to minor changes, in which case the risk to product safety or to environmental protection is quite low. Nevertheless, minor changes should not be approved if either the applicant/design organisation approval (DOA) holder approving minor changes under their privileges, or EASA, is aware of a feature or characteristic that may make the product unsafe for the uses for which certification is requested. ##### GM 21.A.20(d) Final statement *ED Decision 2025/016/R* All compliance demonstrations in accordance with the certification programme, including all the inspections and tests in accordance with point [21.A.33](#_DxCrossRefBm485230474) and all flight tests in accordance with point [21.A.35](#_DxCrossRefBm485230485), should be completed before the issuance of the final statement of compliance required by point [21.A.20](#_DxCrossRefBm485230342)(d).
