‘Big Yusuf’s are renewed in the hands of Turkish engineers and rise to the sky


The version development process of the A400M transport aircraft, known as “Koca Yusuf”, which increases the tactical and transportation capabilities of the Turkish Armed Forces and has strategic features, called “retrophit”, is carried out by Turkish engineers in Kayseri.

Light and heavy maintenance of A400M aircraft is carried out only in Kayseri 2nd Air Maintenance Factory Directorate, apart from Airbus facilities.

In the factory, maintenance of the “flying castles” deployed at the 12th Air Transport Base Command in Kayseri and strengthening the strength of the Air Force can be carried out.

Turkey, on the other hand, is the only country that can apply retrofit (maintenance-repair-improvement) to A400Ms, other than Airbus.

With this new step taken, Turkey has made a significant contribution to the country’s economy by increasing its recognition in the world aviation maintenance and repair sector.

2. Air Maintenance Factory Manager, Air Brigadier General Haldun Taşan, told Anadolu Agency (AA) that large propeller-driven aircraft are maintained at the factory.

Emphasizing that the manufacturing and units of the aircraft were made, Taşan explained that the A400M is a transport aircraft with strategic features.

Stating that Turkey is one of the production partners of the A400M aircraft, Taşan said:

“The 2nd Air Maintenance Factory Directorate has very wide capabilities in terms of A400M maintenance. We are the only one in the world where heavy maintenance is carried out outside the Airbus facility. We are the only facility. In addition, our negotiations with Airbus continue. Retrofit activities carried out for the aircraft to reach the current configuration are also carried out in Kayseri facilities. We have 8 more aircraft ahead of us, we will build 8 aircraft in total. We are also open to countries such as Germany and France, and we are in a position to meet their retrofit requests.”

Emphasizing that they have reached a high level in quality standards with Retrofit, Taşan stated that they have also made important progress in terms of world standards by working with Airbus.

“The vision of the 2nd Air Maintenance Factory Directorate is to be a regional maintenance facility”

Taşan said that they are trying to spread this quality in other aircraft and that they are in talks with Europe about maintenance and continued as follows:
“We have meetings from abroad. We also have measures to increase our production capacity. There are countries that are interested in the A400M from friendly countries in our region. We are in talks with each other about these. They toured our facilities and saw our capabilities on site. The cost of one heavy maintenance is approximately 3 million euros. These are large numbers. Depends on the number. We will be happy if we see other European countries in our retrofit facilities. After that, we are candidates here to carry out heavy maintenance in Europe and other countries. Our quality standards are at a level to meet these. The vision of the 2nd Air Maintenance Factory Directorate is to be a regional maintenance facility. In line with these goals, Africa There are also European, Middle Eastern and Asian countries.”

Explaining that applications are made from time to time, Taşan said, “We have meetings, we will receive good news soon. We have a new study on the modernization of the CN-235 aircraft in particular. We are evaluating this with Airbus. We are in a position to give this to France and Korea.” said.

Taşan said that retrofit maintenance can be done abroad in 6 months, and that they believe that this period will be shortened even more with a new learning curve in Kayseri.

Stating that maintenance is carried out in “light” and “heavy”s in a shorter time than abroad, especially in C maintenance, Taşan said, “We worked with Airbus in retrofit activities here, and we brought our standards to an international position. In return, we want to get jobs from the countries of the region and Europe and be beneficial to the economy.” he said.

Taşan added that the factory works entirely with Turkish technicians and engineers, and the number of personnel receiving training is increasing day by day.
