That proseal on the wing wiring conduit hasn't set yet (probably 'cos its winter here and getting colder each day). So I double checked the aileron bellcrank/pitot tube and the tube will definitely rub on the bellcrank. I'm not happy with that, so I'll get an adel clamp and clamp the tub against the spar (using a convenient hole!) and that will give it the clearance it needs. I guess I'll need to send an order to Spruce. Meanwhile, I measured the pitot tube length I'll need, with a little to spare for future maintenance, and then used silicon to hold it in place in the bushes, just like I did with the proseal on the wiring conduit. I left the two bays around the aileron bellcrank access until I do the clamping, etc. Hopefully, the silicon and proseal will be all set by Sunday and we can at least rivet on the bottom inboard wing skin.
