The FAA proposes to adopt 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 proposed AD was prompted by reports of leaks on closed fuel low pressure shut-off valves (LPSOVs). This proposed AD would require repetitive leak checks of certain fuel LPSOVs and replacement of an affected part if any discrepancy is detected. This proposed AD would also allow the installation of an affected part under certain conditions. The FAA is proposing this AD to address the unsafe condition on these products.
