Unsafe Condition
Wing upper skin joints being manufactured without sealant, which allows water to enter and stay in sealed, bonded stringers. Left uncorrected, corrosion could develop, and freeze/thaw cycles of water could cause deformation of the skin with follow-on disbonding between the stringer flanges and the inner surface of the wing skin, reducing the structural integrity of the wing.
