The instructions ask us to check the wing for twist after the fuel tank has been cleco'd to the spar and the T912 attach brackets have been drilled to the wing. I am curious...why do the instructions ask us to check for twist now? It seems strange.
The reason I ask is I have one wing that has 1/32nd of twist and the other wing has 3.5-4/32 of twist. No matter what I do, I am unable to work the twist out of the wing, short of pulling it out by the rear spar and clamping it down.
How tight does the measurement have to be and when is it critical to have it right on?
