## Abstract

We are superseding Airworthiness Directive (AD) 2009-11-08, which applied to certain Airbus Model A330-202, -223, -243, -301, -322, and -342 airplanes. AD 2009-11-08 required repetitive special detailed (high frequency eddy current) inspections to detect cracking of the keel beam fitting horizontal flange edge at a certain frame (FR) on the left- and right-hand sides of the fuselage, and repair if necessary. This AD was prompted by a new fatigue and damage tolerance evaluation that concluded the current inspection thresholds and intervals had to be modified. This AD requires contacting the FAA to obtain instructions for addressing the unsafe condition on these products, and doing the actions specified in those instructions. We are issuing this AD to address the unsafe condition on these products.
