Would you like to start a business in aviation and don’t know how to deal with the paper? Or would you like to know more about the so called “Initial and Continuing Airworthiness”?

Ok, I will try to provide you here with an overview, simple and concise, so that we do not need to loose ourselves within the forest of the complicated details of the EASA regulations, which you know …it is something like tremendous.

However, if you would like to have a bit of sense on what the EASA Regulation is and HUGE it is, you may have a look at the EASA’ webpage dedicated to the “Regulations”:

You will see that it looks a bit too much for a human being.
Perhaps some AI or intelligent robot will soon take over their jobs, in order to make it more efficient and quick! 😀

Anyway, what I’d like to clarify here is about a simple cycle which involves aircraft, engine, components and its use.

To do so, let me first introduce you a very simple definition given by the EASA for Product and Part.

A ‘product’ means an aircraft, an engine or a propeller.

A ‘part’ means any element of a product (as defined by that product’s type design).

Whatever is the product or the part you want to focus on, it needs first to be designed, then manufacttured and finally operated, which also means maintained.

For what concerns the design, it this must be done in accordance with certain specifications (CS / Certification Specifications) that are identified by the EASA.

A Design Organisation (DOA) is approved under EASA Part 21/J

The Organisations designing the products (and the modifications and repairs applicable to such products) are called Design Organisations and they are Organisations approved in accordance with the EASA Part 21, subpart J regulation.

An approved Production Organisation (POA) needs to comply with EASA Part 21/G

Once the design is ready, you want somebody able (and authorised) to manufacture such a product or part. There you need a Production Organisation, which is approved under Part 21 subpart G.

After that the product (or part) has been first designed and then produced, it can be used but, especially in aviation, it will need a lot of maintenance and technical support.

This is why there are the so called “Continuing Airworthiness Maintenance Organisations” (CAMOs) and the Approved Maintenance Organisations (AMOs), which are those with mechanics and engineering who carry out the actual maintenance.

An approved Maintenance Organisation needs to comply with the EASA Part 145 requirements.

Now you know some further detail about the amazing regulatory crucibles of the aircraft and its parts, even though this is really the very beginning of the story.

There are indeed rules for operations, airspace, pilots, drones, engineers, air traffic controllers etc. for which you might want to visit the EASA website All of them have something to do with all the steps that we have gone through….

Ok, I hope that this small article was of some interest to those who need an initial understanding on who is doing what and according to which rule.

Thank you and good luck!
