Airworthiness Directive · Amendment 39-12364 · Airbus Model A330-301, -321, -322, -341, and -342 Series Airplanes and Airbus Model A340 Series Airplanes
Airbus Model A330-301, -321, -322, -341, and -342 Series Airplanes and Airbus Model A340 Series Airplanes
Model A330-301, -321, -322, -341, and -342 series airplanes, as listed in Airbus Service Bulletin A330-57-3021, Revision 03, including Appendices 01 and 02, dated November 5, 1999; and Model A340 series airplanes, as listed in Airbus Service Bulletin A340-57-4025, Revision 02, including Appendices 01 and 02, dated November 5, 1999; certificated in any category.
This amendment supersedes an existing airworthiness directive (AD), applicable to certain Airbus Model A330-301, -321, -322, and -342 series airplanes and certain Airbus Model A340 series airplanes, that currently requires reinforcement of the wing structure at the inboard pylon rear pickup area. This amendment revises the applicability to include additional airplanes. The actions specified by this AD are intended to prevent fatigue cracking of the bottom skin and reinforcing plate of the wing due to bending, which could lead to reduced structural integrity of the airplane wing. This action is intended to address the identified unsafe condition.
