Summary
We propose to adopt a new airworthiness directive (AD) for all Airbus SAS Model A330-200 Freighter series, Model A330-200 series, Model A330-300 series, Model A340-200 series, Model A340-300 series, Model A340-500 series, and Model A340-600 series airplanes. This proposed AD was prompted by a report that certain sensor struts, in the case of down drive element disconnection, would be unable to provide failure detection information. This proposed AD would require repetitive inspections of certain drive station elements and sensor struts; an inspection of certain other drive station elements if necessary; and corrective actions if necessary. We are proposing this AD to address the unsafe condition on these products.
