Just a limited amount of progress today. The routing of the rudder cables takes them through a cut out in the outer edges of the seat bottoms. To keep them out of the way a cover was fabricated and riveted to the seat bottom and screwed into tabs 120-122 welded onto the side rail that forms the bottom of the door frame. This provides a neat solution to locating the seat cushion and avoiding any risk of the rudder cable fouling.
