Based on the EU Regulation (EU) 2018/1139, the EU Commission has issued amongst others 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.

At the end of this 4 days 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.

A basic understanding of the subjects dealt with in the training course is an advantage, but not necessary.
