That is correct. When we own the intellectual property, we can perform work at the highest level on the platforms that we purchase. So we are talking about engineering work, not just aircraft maintenance. It means engineering. It also means looking for solutions to problems that can arise after a certain number of flying hours, or before problems arise, relying on tests that can be done jointly with research institutes, and so on.
So it is extremely intricate. Many people underestimate the quality that goes into aircraft maintenance work. Not only does a lot of money go into it, but also a lot of time, because the platforms that we purchase usually have a lifespan of 20 to 30 years.
