Service Center Terlet organizes workshops on a regular basis.
The Composite workshops is organized every three year. This workshop covers two days in a weekend.
Theory and practice will go hand-in-hand these two days and you will be prepared for a basic sandwich repair and the painting of it.
Below you will find a testimonial of one of the students of our workshop in 2001.
The start is immediately of a high level.

Louis van Rijn presents a very interesting presentation about the possibilities and restrictions of Composite gliders. We can refresh our knowledge. The thing that I remembered most is that the maximum speed of a Composite glider is really the maximum speed.
The stories that above the maximum speed there is a safety factor of 20% before the wings show flutter indications are very stubborn. Flutter can already start at 10% above maximum speed.

Hitting a hole in the wing.
After this presentation we receive practical work instructions of Peter Jansen, Managing Director of Service Center Terlet, and we start working in pairs. The wings of an Astir a divided in eight blocks. We have to hit a hole in the wing. The students show during this task with enthusiasm, most likely because it is not a glider of their own club. The objective is to repair this hole professionally. Together with Sjoerd van den Berg I do my upmost best to keep up the honour of the Frisian Aero Club. First we repair the lower laminate and we attach a layer of divinicell. Then we start with the preparation and finishing of the upper laminate.
The next day is planned for painting and polishing.
Theory and practice.
 The workshops is a good mix of theory and practical experience. Peter Jansen and the Composite miracle ‘Bobo’ Slobodan Djandara were well prepared, give excellent instructions and seem to enjoy it themselves. From the other technicians we can learn a lot.
Numerous experiences are changed between the students. It is very exciting to see all these men and one women, Monique van Tilburg, working hard. Only a few times some of the technicians were looking to the gliders flying overhead Terlet. I hear someone saying: ‘the workshop is perfect, only the next time they have to change the weather slightly.’
A look inside the kitchen
 Who looks around carefully get’s an impression how they work within Service Center Terlet. Big repairs to gliders are approached professionally according to me. I review the repair of an LS-4 that landed in the high voltage electricity cables. When I see the pin-wire bars I can see clearly these bars safe lives.
I ask Peter Jansen:
‘Why do you give your professional knowledge to us? What we repair ourselves is lost revenue for you?’. ‘That’s correct’, says Peter, ‘we have thought about this before we said yes to the workshop concept’. ‘We are convinced that every gliding club should do the small work themselves and that you leave the big repairs to us’. ‘You can see and judge for yourselves here what we can at this moment’.

At the last part of the workshop quality inspector Jan Vermeer comes in to review the quality of our work. This respected head of the technicians gives us the certificate and from the personal chat he has with every student shows he knows all technicians in the Netherlands.
The end
Peter, Bobo and all SCT employees, this workshop was fantastic! At the end I understand that there will also be a Carbon workshop.
