The AOA plumbing is intact (passes manometer tests) except for a leak at the wing-to-fuselage junction, where the little aluminum tube connects the fitting on the wing to the one on the fuselage. Has anyone else run into this? How did you solve it? I've thought of a couple wraps of teflon pipe joint tape, or some kind of goo (e.g. Dow 4 silicone), or replacing with one continuous line from AOA port to AHARS box.
