OVERHEAD PLENUM. Drain Installation #1


The plans call for installation of an aluminum tube between the back of the overhead plenum and the bottom of the fuselage for drainage of water entering through the roof’s fresh air NACA. I believe this to be an overkill and a cumbersome installation. I decided to permanently install one short piece of aluminum tubing on the plenum and another one on the bottom of the fuselage with flox and connect them with a plastic hose for drainage. This is a much simpler installation with the ability to inspect for possible obstructions and easy replacement of the hose, when needed.
