## Abstract

The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A321-111, -112, -131, -211, -212, -213, -231, -232, -251N, -252N, -253N, -271N, -272N, -251NX, -252NX, -253NX, -271NX, and -272NX airplanes. This AD was prompted by the identification of an erroneous value of the main landing gear (MLG) tire width in the aircraft data files used for aircraft performance computation. This AD requires revising the existing airplane flight manual (AFM) to incorporate a complementary performance data file (CPDF) update as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
