Still some parts to deburr. I first did the forward fuselage angles, they also need to be countersunk and there are ten of them. Then I deburred the seatback angles (eight of them), and finally I did the seatback hinges (ten).

Deburring of the forward side skins : it is very long and boring. I also deburred the edges and rolled those that needed it (it's to avoid they stick out after riveting).

Deburring of the firewall. No problems with the aluminium parts, but the steel and inox parts are a bit more difficult. I also countersink one of the angles.

Both longerons need to be prepared before priming. The inside is deburred and the outside is countersunk. There are two hundred holes per longeron to countersink.
During this time, Sabine began tackling the deburring of the forward fuselage skins.

Next work today is dimpling all the small parts from the forward fuselage : the armrests, the auxiliary bulkheads, the bagage side covers. There are some specific things to do : a nutplate here, a different rivet size there.
