Lots of visible progress today, so this is part 1 of 2 (limit 3 photos per entry). Drilled the verticals of the 2 L angles that brace the seat sides. Then temporarily installed the seat bases to fix the final location of the Ls and back drilled. Then removed the seat bases.
Before mounting the cabin sides, I test fitted on the rear fuselage to make sure the longerons did not touch the baggage back. There was clearance on mine. Removed them from the rear fuselage and cleco'd to the cabin floor. Continued next entry.
