Summary
We propose to adopt a new airworthiness directive (AD) for all Airbus Model A330-200 Freighter, -200, and -300 series airplanes; and Airbus Model A340-500, and -600 series airplanes. This proposed AD was prompted by reports that non-conforming aluminum alloy was used to manufacture several structural parts on the inboard flap. This proposed AD would require identification of the potentially affected inboard flap parts, a one-time eddy current inspection to identify which material the parts are made of, and depending on findings, replacement with serviceable parts. We are proposing this AD to detect and correct structural parts of inboard flaps made of nonconforming aluminum alloy, which could result in reduced structural integrity of the airplane.
