This AD is the result of some critical rivets on the wing not being fully age-hardened and being installed in specific locations where reduction in rivet strength reduces wing strength. The actions specified in this AD are intended to ensure wing ultimate load requirements are met. If wing ultimate load requirements are not met, wing failure could result with consequent loss of control of the airplane.
