Summary
We propose to supersede airworthiness directive (AD) 2008-14- 17, for certain Airbus Model A330-200 and A340-300 series airplanes. AD 2008-14-17 currently requires a high frequency eddy current (HFEC) inspection, corrective actions if necessary, and modifications. Since we issued AD 2008-14-17, it has been determined from a fatigue and damage tolerance evaluation that the compliance time needs to be revised. This proposed AD would require the same actions as those required by AD 2008-14-17, but with a reduced compliance time. We are proposing this AD to detect and correct damage of the upper shell structure at the skin and frame interface, which could result in reduced structural integrity of the airframe.
