Airworthiness Directives; Airbus Airplanes

We are adopting a new airworthiness directive (AD) for certain Airbus Model A330-200 Freighter, -200, and -300 series airplanes. This AD was prompted by a report of a manufacturing defect that affects the durability of affected parts in the cargo and cabin compartment. This AD requires an inspection of affected structural parts in the cargo and cabin compartments to determine if proper heat treatment has been done, and replacement if necessary. We are issuing this AD to prevent crack initiation and propagation, which could result in reduced structural integrity of the fuselage.
