Bertrand Cardis et Gregoire Metz Décision

Grégoire METZ, appointed new general manager of  DECISION S.A.

On the eve of the new challenge, Grégoire Metz, 45, a naval engineer takes the helm of Décision S.A.

After more than 30 years of developing innovative projects in his Ecublens' workshops, Bertrand Cardis has asked to step down from the business's operational management in order to devote part of his time to new projects for Groupe Carboman.

"I asked to step down from the management of Décision in order that I might spend more time on special projects, in particular in the field of aeronautics. We worked for more than ten years in the construction of two solar planes -SOLAR IMPULSE and SOLAR IMPULSE 2- and we have developed a unique knowledge in this field. For us, it's now wise to make the most of this expertise", said Bertrand Cardis.

The former manager will remain in Groupe Carboman as both a shareholder and an administrator.

A collaboration since 2003

Décision-Groupe Carboman is proud to have collaborated with Solar Impulse since the beginning of the project, in May 2003, and becoming one of the key partner. The swiss company based in Ecublens was in charge of the production of the main carbon structures for both planes, HB-SIA and then S2, especially for the wings longitudinal beams, the fuselage, the engines and the pilot cockpit support system.
