The training course aims to provide a broad range of staff with knowledge and understanding regarding the tasks and responsibilities of applicants and holders of Type Certificates (TC) and Restricted Type Certificates (RTC) addressing the requirements of Design Organization Approvals (DOA), and Production Organisation Approvals (POA) including changes to TC or RTC, Supplemental Type Certificates and Repair approvals.

Based on the EU Regulation (EC) 2018/1139, the EU Commission has issued Regulation (EU) 748/2012. Annexed to this Regulation is Annex I - Part 21, with Section - A Technical Requirements and Section B - Procedures for Competent Authorities. In addition, the EU Commission issued Regulation  (EU) 2022/201 and (EU) 2022/203 on 14 February 2022 amending Commission Regulation (EU) No 748/2012 introducing a requirement to operate a Safety Management System in the Production as well as in the Design Organisation. 

This course presents in general terms the legal and regulatory system, as defined by the regulations identified above. It addresses the EASA design and production organisation approval process and under which conditions a Type Certificate, Restricted Type Certificate, a Supplemental Type Certificate, and an ETSO Authorisation will be issued by EASA.

Also, the classification of changes and repairs will be explained, and under which conditions changes and repairs are approved by EASA or alternatively approved by an approved Design Organisation. The conditions under which Competent Authorities shall issue Certificates of Airworthiness, Noise Certificates, and Production approvals are addressed as well and also the different options regarding the issuance of the Permit to Fly by either the Competent Authority, the approved Design – or Production Organisation will be addressed.

At the end of the training, attendees will have a general understanding of Annex I - Part 21, Section A and Section B. 

Note: The handout material, e.g. the powerpoint presentations book and the EASA Easy Access Rule of Annex I - Part 21 can be consulted during the JAA-TO e-examination.
