## Abstract

We are adopting a new airworthiness directive (AD) for certain Airbus Model A330-301, -321, -322 and -342 airplanes. 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. This AD was prompted by a report of cracking in the top skin of the horizontal stabilizer (HS) center box (CB) of an airplane in pre-modification 41330 configuration. We are issuing this AD to address the unsafe condition on these products.
