From four spar caps, the front and rear spars were constructed. In the space between the upper and lower caps are the webs and pillars that connect the two. The pillars in particular deserve closer attention: they serve to transfer loads, for example from the undercarriage, and may at first glance look like simple wooden blocks. In fact, they are made from cross-laminated spruce boards. The grain direction was also critical in the webs: it had to run vertically there, while t
