GM1 21L.A.21 Scope ED Decision 2023/013/R A type certificate (TC) that is issued under Subpart B of Annex I (Part 21) has the same validity as a TC that is issued under Subpart B of Annex Ib (Part 21 Light). However, the eligibility for design organisations is different (e.g. declared design organisations using Subpart J of Annex Ib are permitted to apply for a TC), and also the means of verifying compliance is different. In addition, the production organisation requirements are also different, and organisations are permitted to become declared production organisations using Subpart G of Annex Ib (Part 21 Light) and produce products and parts within the scope of point [21L.A.21](#_DxCrossRefBm1649097718). As per point [21L.A.23](#_DxCrossRefBm1649097313)(b), an organisation that holds a design organisation approval (DOA) issued under Subpart J of Annex I (Part 21) meets the eligibility criteria of Subpart B of Annex Ib (Part 21 Light).

Furthermore, an organisation that holds a production organisation approval (POA) issued under Subpart G of Annex I (Part 21) is permitted to use that approval to release products and parts within the scope of Subpart B of Annex Ib (Part 21 Light), and use the privileges that are granted under that approval (as per point [21.A.163](#_DxCrossRefBm1649096916)(b) of Annex I (Part 21)) and further described under points [21L.A.143](#_DxCrossRefBm1649097272)(c)(1)(ii) and [21L.A.163](#_DxCrossRefBm1649097271)(c)(1)(i)(C) of Annex Ib (Part 21 Light). ##### GM1 21L.A.21 Scope *ED Decision 2023/013/R* A type certificate (TC) that is issued under Subpart B of Annex I (Part 21) has the same validity as a TC that is issued under Subpart B of Annex Ib (Part 21 Light).
