damage (crocking, corrosion, structural defonnauon, and dents) ofille

center wing box of the lower surface, and corrective actions if necessary.

box aHhe lower surface. We are proposing this AD to detect and correct

such cracks, which (;ould affect the structural failUre of the wings.

DATES: W""must r~ceive comments on this proposed AD by [i.l1sen date
