the disconnection of the high level switches on the affected helicopters.  Disconnecting the switches inhibits the high (fuel) level warning system which normally informs the flight crew of the risk of fuel overflowing from the tank vents.  To mitigate that risk, this Directive also requires, for certain helicopters, the installation of a placard near the fuel panel, limiting the transfer of fuel between fuel tank groups to cases where the receiving fuel tank group contains less than 300 litres (240 kg or 529 lbs).

   This Directive is considered to be a temporary measure and further rulemaking is likely to follow.
