Summary
We propose to adopt a new airworthiness directive (AD) for certain Airbus SAS Model A330-200 Freighter, -200 and -300 series airplanes; and certain Airbus SAS Model A340-200, -300, -500, and -600 series airplanes. This proposed AD was prompted by a determination that certain wing slat tracks that were inadvertently indicated as eligible for installation on all Model A330 and A340 series airplanes are unable to sustain the ultimate loads relative to the weight variant of certain airplane configurations. This proposed AD would require inspecting any affected part for cracking, and replacing with a serviceable part, as specified in an European Aviation Safety Agency (EASA) AD, which will be incorporated by reference. We are proposing this AD to address the unsafe condition on these products.
