Airworthiness Directives; Airbus Airplanes
We are superseding Airworthiness Directive (AD) 2011-14-10, which applied to certain Airbus Model A330-342 airplanes. AD 2011-14-10 required repetitive ultrasonic inspections for cracks of a certain fuselage frame at the fastener hole area just above a certain stringer, and repair, if necessary. This new AD was prompted by a new fatigue and damage tolerance evaluation, which showed that certain inspection thresholds and intervals need to be shorter. This AD requires contacting the FAA to obtain instructions for addressing the unsafe condition on these products, and doing the actions specified in those instructions. We are issuing this AD to address the unsafe condition on these products.
