Based on the EU Regulation (EC) 216/2008, the EU Commission has issued, amongst others, the Regulation (EU) 748/2012. Annexed to this Regulation is Annex I ( Part 21), Certification of aircraft and related products, parts and appliances, and of design and production organisations. JAA TO has developed this course to help understanding of these changes.

The general course breakdown for this 3 day training course is as follows:

1) During the first day and second day of the training course, the legal and regulatory system, as defined by the Regulation (EC) 216/2008, will be explained in general terms.

2) This will be followed by a detailed presentation of Annex I (Part 21), addressing the main topics, including the relevant AMC & GM.

3) During the third day of the training course, Subpart J – Design Organisation Approval, including the AMC & GM,  will be presented in detail.

At the end of this 3-day training course, the attendees should have a detailed understanding of all the steps necessary to obtain an EASA Design Organisation Approval, the tasks and responsibilities of such an organisation and all relevant certification processes.
