AMC1 21L.A.9(b) Instructions for continued airworthiness ED Decision 2023/013/R IDENTIFICATION OF A COMPLETE SET OF INSTRUCTIONS FOR CONTINUED AIRWORTHINESS (ICAs) The design approval holder (DAH) or declarant should identify the complete set of ICAs according to point [21L.A.9](#_DxCrossRefBm1649097761)(b) in such a way that the complete set can be: (a)     directly listed in the product’s type certificate data sheet (TCDS) or airworthiness data sheet; or (b)     indirectly referenced in the TCDS or airworthiness data sheet through other means, which allow the complete list of the ICAs to be obtained (e.g. a complete listing of ICAs contained in a ‘principal manual’ or a reference to the DAH’s or declarant’s website); or (c)      directly listed in the product’s supplemental type certificate (STC); or (d)     indirectly referenced in the STC through other means, which allow the obtainment of the complete list of the ICAs; or (e)     if direct reference is made to the ICAs in the product’s TCDS or the STC or airworthiness data sheet, no reference to the revision level of the ICAs should be made; in this case, the revision level should be available elsewhere (e.g. on the DAH’s or declarant’s website). For design changes and repairs to type certified or declared aircraft, the identification of ‘a complete set of the changes to the instructions for continued airworthiness’ should be performed by the DAH or declarant by a statement to provide this information, or by confirmation that there are no changes to the ICAs. This statement may also be made in the accomplishment document (e.g. embodiment instructions). For products and articles for which the DAH or declarant holds a design organisation approval (DOA), the ICAs are considered to have been issued under the authority of the DOA and, therefore, the approval of the ICAs should be made explicit to the reader in accordance with point [21.A.265](#_DxCrossRefBm1649096943)(h) of Annex I (Part 21) to this Regulation, unless otherwise agreed with EASA. ##### AMC1 21L.A.9(b) Instructions for continued airworthiness *ED Decision 2023/013/R* **IDENTIFICATION OF A COMPLETE SET OF INSTRUCTIONS FOR CONTINUED AIRWORTHINESS (ICAs)** The design approval holder (DAH) or declarant should identify the complete set of ICAs according to point [21L.A.9](#_DxCrossRefBm485231257)(b) in such a way that the complete set can be: (a) directly listed in the product’s type certificate data sheet (TCDS) or airworthiness data sheet; or (b) indirectly referenced in the TCDS or airworthiness data sheet through other means, which allow the complete list of the ICAs to be obtained (e.g. a complete listing of ICAs contained in a ‘principal manual’ or a reference to the DAH’s or declarant’s website); or (c) directly listed in the product’s supplemental type certificate (STC); or (d) indirectly referenced in the STC through other means, which allow the obtainment of the complete list of the ICAs; or (e) if direct reference is made to the ICAs in the product’s TCDS or the STC or airworthiness data sheet, no reference to the revision level of the ICAs should be made; in this case, the revision level should be available elsewhere (e.g. on the DAH’s or declarant’s website).
