How do I check my fuselage fittings vertical location to determine if they are correct? Im other words whether wing angle of incidence will be correct. Should they be the same height with the fuselage in a level attitude?

It is a 63 7EC

Thanks!

Jeff,
Unless the fuselage has been damaged this point can't be easily changed.
Level the plane on the longitudinal axis and use this point to get the measurement to the fittings. You should be able to make a triangle from the points and with a little math figure for the angle. Or zero a smart level on the longitudinal axis and measure between the fittings.

Thanks Paul.

I was confusing line of the bottom of the butt rib with the wing cord which I now realize is different and they are not parallel.

Thanks

Jeff,
What are you trying to do to the airplane? Repair work will need the correct print for accomplishment. I you're not satisfied with the rig of the plane that would be a little different. Let me know if I can help.

I'm installing and rigging the wings after rebuilding. No damage to the fuselage and the angle of incidence is fine once I figured it out.
