Summary
We propose to supersede Airworthiness Directive (AD) 2009-18- 16, for certain Airbus Model A310-203, -204, -221, -222, -304, -322, - 324, and -325 airplanes. AD 2009-18-16 requires an inspection for cracking of certain fastener holes on certain frames, and related investigative and corrective actions if necessary; and modification of certain fastener holes. Since we issued AD 2009-18-16, an evaluation by the design approval holder (DAH) indicated that the compliance times should be reduced. We are proposing this AD to address the unsafe condition on these products.
