Today, I removed the port fwd and centre skins. I checked the angle of the flanges on the various bulkheads and armrests etc, most were just off the 90 degrees angle by a tiny amount, so I adjusted them to the 90 degree requirement. I then reclecoed the port skins back onto the fuselage. I removed the starboard side fwd and centre skins, and will deal with the bulkhead, armrest adjustment, if needed, tomorrow. I am doing one side at a time because I'm concerned that the fuselage would sag without the skins clecoed in place. Indeed the fuselage sags about 1/4 of an inch with the skins off of one side of th fuselage.
