GM1 21L.B.183(b) Oversight ED Decision 2023/013/R CRITICAL DESIGN REVIEW, PHYSICAL INSPECTION AND FIRST-ARTICLE INSPECTION The oversight of a declared design organisation should be built around the product design and the investigations performed by EASA during the certification or the registration of a declaration of design compliance. These investigations are performed as follows: (a)     for the certification of design compliance: (1)     a critical design review is performed, as applicable, before the approval of the flight conditions (see point [21L.B.242](#_DxCrossRefBm1649097844)(a)(1) and (a)(3)); (2)     a physical inspection is performed, as applicable, before the approval of the flight conditions (see point [21L.B.242](#_DxCrossRefBm1649097844)(a)(1) and (a)(3)); and (3)     a physical inspection of the first article (first-article inspection) is performed, as applicable, after receiving the declaration of compliance and before the issuance of the respective product design certificate or approval (see points [21L.B.46](#_DxCrossRefBm1649097807)(c), [21L.B.83](#_DxCrossRefBm1649097897)(c), [21L.B.102](#_DxCrossRefBm1649097928)(c) and [21L.B.203](#_DxCrossRefBm1649098100)(c)); (b)     for a declaration of design compliance: (1)     a physical inspection is performed, as applicable, before the approval of the flight conditions (see point [21L.B.242](#_DxCrossRefBm1649097844)(a)(2) and (a)(4)); and (2)     a physical inspection of the first article (first-article inspection) is performed, as applicable, after receiving the declaration of design compliance and before the registration of the respective declaration (see points 21.B.62(b), 21.B.121(b) and [21L.B.221](#_DxCrossRefBm1649098132)(b)). Note: The physical inspections mentioned above are: —    for a certified product: compliance inspections during which EASA verifies that the product is compliant with the applicable type-certification basis and the applicable environmental protection requirements; —    for a declared aircraft: safety inspections during which EASA ensures that the aircraft is capable of safe flight and environmentally compatible; these physical inspections may include ground, functional and flight tests, as relevant. For the contents and methodology to perform critical design reviews, physical inspections and first-article inspections, refer to [AMC2 21L.B.46(c)](#_DxCrossRefBm1649098238), AMC1 21L.B.62(b), AMC1 21L.B.241(a)(1) and point 21L.B.242(a)(1), and AMC 21L.B.241(a)(2) and point 21L.B.242(a)(2). ##### GM1 21L.B.183(b) Oversight *ED Decision 2023/013/R* **CRITICAL DESIGN REVIEW, PHYSICAL INSPECTION AND FIRST-ARTICLE INSPECTION** The oversight of a declared design organisation should be built around the product design and the investigations performed by EASA during the certification or the registration of a declaration of design compliance.
