So the preflight is done, and it’s time to fly. Take off and notice the ASI is not working and then, jumps slowly to speed. Sluggish, but working. Back to the hangar.

Pull the wingtip off the plane, pulled the tubing off the pitot tube and blew air backwards through it, nothing but a little dust.

Take the AN fitting on the pitot line off the fuselage nipple under the left sump cover. Blow air back out the wing. This is what came out.

Cheers
