Airworthiness Directives; Airbus SAS Airplanes

The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A330-243, A330-243F, A330-341, A330-342, A330-343, A330-841, and A330-941 airplanes; and Model A340-211, A340-212, A340- 213, A340-311, A340-312, A340-313, A340-541, and A340-642 airplanes. This AD was prompted by reports of leaks on closed fuel low pressure shut-off valves (LPSOVs). This AD requires repetitive leak checks of certain fuel LPSOVs and replacement of an affected part if any discrepancy is detected. This AD also allows the installation of an affected part under certain conditions. The FAA is issuing this AD to address the unsafe condition on these products.
