## Abstract

The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A330-323, -342, and -343 airplanes. This AD was prompted by the discovery of an erroneous value in some airplane data files that are used for performance computations in the airplane flight manual (AFM). This AD requires revising the existing AFM and applicable corresponding operational procedures, 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.
