Abstract
We are adopting a new airworthiness directive (AD) for certain Airbus Model A330-200, A330-300, A340-500, and A340-600 series airplanes. This AD requires a detailed inspection for cracked and missing nuts, and replacement of cracked or missing nuts with new nuts having the same part number. This AD was prompted by reports of cracked nuts detected during production. We are issuing this AD to detect and correct cracked or missing nuts, and replace all affected nuts in multiple locations (including fuel tank areas) that could result in reduced structural integrity of the airplane.
