Summary
The FAA proposes to supersede Airworthiness Directive (AD) 2016-07-14, which applies to certain Airbus Model A319-111, -112, -113, -114, -115, -131, -132, and -133 airplanes; Model A320-211, -212, -214, -231, -232, and -233 airplanes; and Model A321-111, -112, -131, -211, - 212, -213, -231, and -232 airplanes. AD 2016-07-14 requires replacing the clips, shear webs, and angles, related investigative actions, and repair if necessary. Since the FAA issued AD 2016-07-14, it has been determined that the fatigue life associated with the clips, shear webs, and angles is not sufficient to reach the limit of validity (LOV) in certain configurations; therefore, additional modifications to the airplane are required. The FAA has also determined that additional airplanes are subject to the unsafe condition. This proposed AD would retain the actions of AD 2016-07-14, and require modifying (replacing) the clips, shear webs, and angles at a certain rear fuselage area with new parts, as specified in a European Union Aviation Safety Agency (EASA) AD, which will be incorporated by reference. The FAA is proposing this AD to address the unsafe condition on these products.
