21L.A.121 Scope

APPLICABLE DESIGN DATA Applicable design data is defined as all necessary drawings, specifications and other technical information provided by the applicant for, or holder of, a design approval to be issued in accordance with this Annex or by a natural or legal person that has declared or intends to declare the compliance of the aircraft design in accordance with this Annex, and has released it in a controlled manner to a declared production organisation. This should be sufficient for the development of production data to enable repeatable manufacture to take place in conformity with the applicable design data. Prior to the issuance of the type certificate (TC), supplemental type certificate (STC), approval of the changes to the TC/STC or approval of the repair design, design data is defined as ‘non- approved’ but parts may be released with an EASA Form 1 as a certificate of conformity. After the issuance of the TC, STC, approval of the changes to the TC/STC or approval of the repair design, the design data is defined as ‘approved’ and items manufactured in conformity with this data are eligible for release on an EASA Form 1 for airworthiness purposes. When the compliance of the aircraft design and any subsequent compliance of any changes to the design or the repair design are subject to a declaration according to the requirements of Subparts C, F or N respectively of Annex Ib (Part 21 Light) to Regulation (EU) No 748/2012, the design data is considered ‘non-approved’. However, a distinction can be made between the status of the data before the issuance of the declaration and after. This will be indicated in Block 12 ‘Remarks’ of the EASA Form 1. Note: For the EASA Form 1 layout, contents and instructions for completion, please refer to Appendix I to Annex I (Part 21) to Regulation (EU) No 748/2012. For the purpose of Subpart G of Part 21 Light, the term ‘applicable design data’ includes the information related to the applicable environmental protection requirements.
