Description

The FAA proposes a new airworthiness directive (AD) for all Airbus SAS Model A330 and A340 series airplanes. This AD addresses reports of leaks on closed fuel low pressure shut-off valves (LPSOVs) which could sustain a fire if not corrected. The directive requires repetitive leak checks of certain fuel LPSOVs and replacement of affected parts if discrepancies are found. It also allows installation of affected parts under certain conditions to ensure safety.
