I feared that the pitot line was kinked in the wing root from when we zip tied the wires together while inserting the wings. That would mean that the wing bolts would need to be removed and the left wing slid out a few inches to access....that would be a bear of a job! I started looking there with the borescope through the fuel line acess panels and pulled off the wire root tape to see what I could see through the gap. Everything I saw looked good.
Plan was to re-rerun a new line from the fuselage to the tips, so pulled front seat and forward panel out. Decided to pull wing tip off on try to establish whether the line was open before I started hacking away.
When I opened the tip up, I found that the metal connector from pitot tube to nynaflow 90 degree fitting was very loose... must have missed tightening it when installed. Pulled it out and rigged up a line that I could blow into and watch the AS indicator in the panel..... got a nice reading...was able to blow it to over 200 knots. Concluded the line was clear and not kinked, although it may be leaking somewhere else. Right now I am assuming that the losse connection was the culprit. Will re-install pitot line and everything else tomorrow when I am fresh.
