For MSN001, the winglets have been customised with a nice gradation of blue which has required a special mix of colours, a real work of art for the painters.
Painting takes place in a new facility at Clément Ader site. In this new paintshop, there are specific equipment to support the new shapes while allowing the best ergonomic position for the painter.
The A320 sharklets are also painted in the same hall by the same team.
