Airworthiness Directives; Airbus SAS Airplanes

The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A318-112; Model A319-115, -132, and -133; Model A320-214, -216, -232, -233, -251N, and -271N; and Model A321-211, -213, -231, -271N, -251NX, -253NX, and -271NX airplanes. This AD was prompted by a quality escape identified in the production assembly line on the main landing gear (MLG) support rib 5 lugs, which resulted in tool mark damage in the bore of the forward and aft lugs. This AD requires repetitive detailed visual inspections (DVIs) of the affected parts and applicable corrective actions. This AD also provides a one- time special detailed inspection (SDI) as a terminating action for the repetitive inspections. The FAA is issuing this AD to address the unsafe condition on these products.
