EAA Technical Counselor stopped by to inspect left wing and pitot tube installation. He recommended making a couple of loops on the air hoses (see picture) so that if we needed to get to the pitot tube heating unit that we'd have enough hose to drop the pitot tube out of the way. He also recommended putting bulkhead fittings for the tubes in the root rib so we could route the tube through the fuselage without the wing. He also didn't like the scratching around the rivet holes where we de-burred. Touched-up the scratches and we'll use the countersink tool (lightly!) in the future.
