• ED Decision 2019/018/R found in: Initial Airworthiness and Environmental Protection (748/2012) Part-21 Part-21L (Jul 2024)

GM 21.A.131 Scope – Applicable design data ED Decision 2019/018/R Applicable design data is defined as all necessary drawings, specifications and other technical information provided by the applicant for, or holder of a design organisation approval, TC, STC, approval of repair or minor change design, or ETSO authorisation and released in a controlled manner to a production organisation approval holder. This should be sufficient for the development of production data to enable repeatable manufacture to take place in conformity with the design data. Prior to issue of the TC, STC, approval of repair or minor change design or ETSO authorisation, or equivalent, design data is defined as ‘not approved’ but parts and appliances may be released with an [EASA Form 1](#_DxCrossRefBm1649096870) as a certificate of conformity. After issue of the TC, STC, approval of repair or minor change or ETSO authorisation, or equivalent, this design data is defined as ‘approved’ and items manufactured in conformity are eligible for release on an [EASA Form 1](#_DxCrossRefBm1649096870) for airworthiness purposes. For the purpose of Subpart G of Part 21, the term ‘applicable design data’ includes the information related to the applicable engine exhaust emissions and aeroplane CO2 emissions production cut-off requirements. ##### GM 21.A.131 Scope – Applicable design data *ED Decision 2019/018/R* Applicable design data is defined as all necessary drawings, specifications and other technical information provided by the applicant for, or holder of a design organisation approval, TC, STC, approval of repair or minor change design, or ETSO authorisation and released in a controlled manner to a production organisation approval holder.
