I have been thinking about the brake lines running under the rear floor. If I have any issues in the future, I would be unable to access the brake lines under the floor without de-riveting the entire rear floor. So I decided to put two access panels in each side. The access covers I have are too wide, so I cut them down along the hole line each side and re- drilled the holes. Can't imagine why I am taking so long to build this aircraft.
