Hi,
busTRE is right.
You can have a look here:
AIRBUS TECHNICAL SITE
Look at the table 1.27
30 ........ If the failure has caused ALTN LAW (that always turn in DIRECT LAW on anding Gear Down) then DON'T COUNT it (for LDF). If instead it's an INDEPENDENT failure, then you should multiply it's LDF.
Hope it clears.
