Still working on the center fuselage, a lot of small tasks are to be done. First the installation and drilling of the baggage compartment side ribs.



The I backdrilled the seat side ribs. There aws also some fluting to be done before drilling all the ribs, the bulkheads and the skin. To do this, the ribs had to be taken of and installed a few times. On the picture, the side rib which has to be fluted to get the same curve as the skin.



Then I installed the forward part of the main bulkhead and the inner skins. On this part I still have to backdrill the main bulkhead and install the scrotch strap kit.
