EASA Part 21G Certificate of AESC

AESC just received the Production Organization Approval (Part 21G) from European Aviation Safety Agency (EASA) on 18th June 2018 with the Certificate Number EASA.21G.0056. With this Approval, AESC is approved to have in its production non-structural cabin interior parts, providing minor repair service, in compliance with EASA standards, to its customers not only within Vietnam, but also in the region and over the world.

Therefore, we had a small interview with Mr. Ryan and Ms. Jennifer - the ones who mainly in charge of POA Department in the process of approving.


1. First of all, congrats on the company for this achievement. It is known that AESC has been awarded the EASA Part 21G Approval Certificate after a period of 4 years by European Aviation Safety Agency. At the present, AESC becomes the only company in Vietnam that is allowed to manufacture equipment for replacement and repair of aircraft interior. As one of the people directly involved in the validation process, please share with us your feeling? 

Jennifer: Since being involved in this project from the early days, we feel immensely proud of the results we have achieved with so much effort over the past four years. In retrospect, at the beginning, we struggled from lack of resources, including human capacity, facilities, and well-equipped working environment. There were only five of us back then, and although having experience in engineering and manufacturing, we had not been exposed to the aviation field. The achievement today is due to the sweat and tears of our people.


2. Since having considerable working experience, in your opinion, in the field of manufacturing equipment for replacement and repair of aircraft interior, what is the most important factor? To meet the standard, how does AESC invest your resources?

Ryan: The most important factor for us is people. Here, we would like to talk about the people trained to understand and build a system that meets the standards of the European Aviation Safety Agency (EASA). AESC has invested heavily in core human resource training to build and operate the system to achieve this. At the beginning, we needed the support of our consultants from Europe. Once we have grasped the key issues, we have implemented the approval process ourselves.

3. It is known that EASA always requires strict standards of safety, so what challenges did AESC face during the standardization of equipment involved in manufacturing activities such as replacement, repair of aircraft interior to achieve EASA certificate 21 G?

Jennifer: Under the approval process, AESC has encountered many difficulties.

It was difficult at first to build a system that met  new standards while the young and inexperienced workers were first familiarized with the requirements of EASA, specifically Part 21. That was when we decided that it was necessary to have good training courses. We studied with a specialist from France who had just joined us to work with an analyst, system builder, process builder and on-demand forms. After learning and working in order to accumulate some knowledge, we improve the system itself and carry out the process of applying for approval.

Ryan: As a result, AESC has encountered difficulties in finding partners who are suppliers of materials/services that meet the very strict requirements of EASA. It is due to the shortage of capable domestic suppliers in Vietnam.

In order to overcome this difficulty, our technical staff and supply staff need to work harder to expand our range of domestic and foreign suppliers. In addition, we also have a policy to support our suppliers to upgrade the system, build processes, forms and certificates to meet the requirements.

4. In your point of view, what is the role of EASA Part 21 Approval in company’s future development?

Ryan: EASA Part 21 Approval is a milestone marking the maturity of AESC. By achieving this certification, AESC can expand its customer base beyond the national and regional boundaries of the world of aircraft manufacturing. AESC will also have the opportunity to cooperate with other EASA approved design and manufacturing organizations.


5. There are not many EASA approved manufacturing organizations in the region. Could you tell us what makes this distinctive advantage for AESC?

Ryan: There are not many organizations in the region that have received the EASA Part 21G Approval, which is a great advantage, as obtaining this approval means that AESC has the "ticket" to penetrate this niche market of the world's leading manufacturer of aircraft equipment. Besides, this is the base for us to build customers awareness and loyalty since the production system we are operating is fully compliant with the requirements of EASA.

6. What did you personally learn in the process of preparing for approval?

Jennifer: The application process for approval includes understanding the requirements and developing a system that meets the requirements of EASA. In addition, to understand the approval process, we have additional work experience and information exchange with EASA. Their mindset on addressing system management, safety issues, and also how they supervise production organizations is very detailed and methodical.

7. Do you have any prodigious memory throughout the journey?

Ryan: It was our first trip to Europe that strikes me as the most memorable. At that time, Jennifer and I represented AESC at a meeting held annually by EASA for all Design and Manufacturing organizations from around the world. We were also the youngest on the list to attend the meeting. As we presented at the meeting, we had the chance to meet representatives from other organizations, even the largest ones in the world such as BOEING, AIRBUS…

For the first time, AESC, a company from Vietnam, was named in the EASA report on the list of organizations that being approved on design and manufacture. We felt overwhelmingly proud. After the meeting we also met some colleagues from design and production organizations in France and Germany. This is a memorable trip for both of us.

Thank you. Wish AESC will achieve great success in the future!
