By way of derogation from Articles 9 to 13, as appropriate: the compliance with the applicable essential requirements referred to in Article 9 of the design of products, of parts and of non-installed equipment may be assessed without the issuance of a certificate, where the delegated acts referred to in point (d)(i) of Article 19(1) so provide. In that case, the delegated acts referred to in point (j) of Article 19(1) are to define the conditions and procedures for such assessment. The delegated acts referred to in point (d)(i) of Article 19(1) might provide that the organisation responsible for the design and production of those products, parts and non-installed equipment is to be allowed to declare the compliance of their design with those essential requirements and with the detailed specifications established in accordance with the delegated acts referred to in point (i) of Article 19(1) adopted to ensure compliance of those designs with those essential requirements; when the design of an aircraft does not comply with the essential requirements referred to in Article 9, a restricted type certificate may be issued. In that case, that certificate shall be issued upon application, when the applicant has demonstrated that the design of the aircraft complies with the certification basis established in accordance with the delegated acts referred to in point (b)(i) and (ii) of Article 19(1) and that the design of the aircraft is adequate, as regards airworthiness and environmental compatibility, in light of the intended use of the aircraft.
