AMC1 21.A.7(b) Identification of a complete set of instructions for continued airworthiness (ICA) ED Decision 2021/007/R The design approval holder (DAH) should identify the complete set of ICA according to point [21.A.7](#_DxCrossRefBm1649096932)(b) in such a way that the complete set can be: (a)     directly listed in the product TCDS; or (b)     indirectly referenced in the TCDS through other means, which allow the complete list of the ICA to be obtained (e.g. a complete listing of ICA contained in a ‘principal manual’ or a reference to a DAH’s website); or (c)      directly listed in the product STC; or (d)     indirectly referenced in the STC through other means, which allow the obtainment of the complete list of the ICA; or (e)     if direct reference is made to the ICA in the TCDS or the STC, no reference to the revision level of the ICA should be made; in this case, the revision level should be available elsewhere (e.g. on the DAH’s website). For changes to type certificates and repairs, the identification of ‘a complete set of the changes to the instructions for continued airworthiness’ should be performed by the DAH by a statement to provide this information, or by confirmation that there are no changes to the ICA. This statement can also be made in the accomplishment document (e.g. embodiment instructions). For products and articles for which the DAH holds a design organisation approval (DOA), the ICA are considered to be issued under the authority of the DOA and, therefore, the approval of the ICA should be made explicit to the reader in accordance with point [21.A.265](#_DxCrossRefBm1649096943)(h), unless otherwise agreed with EASA. ##### AMC1 21.A.7(b) Identification of a complete set of instructions for continued airworthiness (ICA) *ED Decision 2021/007/R* The design approval holder (DAH) should identify the complete set of ICA according to point [21.A.7](#_DxCrossRefBm485230423)(b) in such a way that the complete set can be: (a) directly listed in the product TCDS; or (b) indirectly referenced in the TCDS through other means, which allow the complete list of the ICA to be obtained (e.g. a complete listing of ICA contained in a ‘principal manual’ or a reference to a DAH’s website); or (c) directly listed in the product STC; or (d) indirectly referenced in the STC through other means, which allow the obtainment of the complete list of the ICA; or (e) if direct reference is made to the ICA in the TCDS or the STC, no reference to the revision level of the ICA should be made; in this case, the revision level should be available elsewhere (e.g. on the DAH’s website).
