I suggest that there was at least another 60 litres in the system.
Where do you get that from Sid?
From the attitude of the ac when the fuel drain was taking place.
The amount of fuel drained would be limited to the level of the drain point, (near to the pump). Much like those boxes of wine, when the level of the wine gets to below the tap you can't pour any more wine out unless you tip the box.
In the scenario of the fwd transfer pump failing above 80 kts, ( greater nose down attitude), the unusable fuel is 59 kgs. Therefore if the ac on the strops is at an angle equal to or greater than the 80 kt attitude, that fuel will not be able to be drained until the ac is level. The same drain point/fuel level explanation applies for the smaller amount not accessible in the supply tanks.
Mind you, the report said that "
approximately 95 litres of fuel were drained from the fuel tank", which doesn't necessarily mean that they drained it until it was empty, perhaps that's as much as their container could hold.
