IR: (EU) No 748/2012
‘Part 21’ means the requirements and procedures for the certification of aircraft and related products, parts and appliances, and of design and production organisations laid down in Annex I (Part 21) to this Regulation.
‘Part 21 Light’ means the requirements and procedures for the certification or declaration of design compliance of aircraft intended primarily for sports and recreational use and related products and parts, and declaration of design and production capability of organisations laid down in Annex Ib (Part 21 Light) to this Regulation.
适用于Part 21 Light的通用航空器设计和制造单位，仍然可以选择按照传统的Part 21进行适航取证 (ELA1/ELA2)，但采用Part 21 Light将获得诸多优势。

Light certified process
来源：EASA
02
Light declared process
这一流程对机构不设设计和生产能力要求；设计和制造单位可直接声明对具体技术规范的符合性；EASA将对上述声明进行登记、但不进行符合性确认；最终，航空器无需取得TC，即可直接取得带限制的适航证，但仅允许在欧盟内部运行。
