Abstract: A method of fabricating an aircraft structural component for an aircraft includes providing a component precursor with a web and a flange. The web has a length, height shorter than the length, thickness shorter than the height, first end proximal to the flange and second end distal from the flange.

Then shaping the component precursor includes curving the component precursor into a curved shape having a first radius of curvature at the one of the first and second ends and a second radius of curvature at the another of the first and second ends, the second radius of curvature greater than the first.
