Systems and methods are provided for fabricating multiple segment spars for an aircraft. In one example the method includes fabricating preforms of fiber reinforced material for spar segments, hardening the preforms to form the spar segments, and bonding the spar segments together to form a completed spar detail. In addition to bonding, other examples include co-curing and fastening the spar segments. In additional examples, the spar segments include kinks or sub-kinks as described.

A method of inspecting a secondary bond of a laminated part includes positioning the laminated part within a sealed chamber. The method also includes reducing a pressure within the sealed chamber to below a pressure outside the sealed chamber when the laminated part is positioned within the sealed chamber. The method further includes, when the pressure within the sealed chamber is reduced to below the pressure outside the sealed chamber, measuring a gradient of change of a surface profile of the laminated part. The method additionally includes determining a condition of the secondary bond based on the gradient of change of the surface profile of the laminated part.
