Check list use
Fuel leak Check list is for leaks between spar valve ( low pressure cutoff valve) and engine . There is no check list ( boeing planes too.. ) dealing with fueĺ leaks before the spar valve wich is shut off by ENG MASTER shut off , such as fuel tanks .
Bolded text by myself .
CASE 1: IF ONE INNER TANK DEPLETES FASTER THAN THE OTHER BY AT LEAST 500 kg IN LESS THAN 30 min:
An engine leak may still be suspected. Therefore:
THR LEVER (engine of affected inner tank) . . . . . . . . . . . . . . . . . . . . . . IDLE
ENG MASTER (engine of affected inner tank) . . . . . . . . . . . . . . . . . . . . .OFF

❖ If leak stops:
If the fuel quantity of the affected inner tank stops decreasing, the engine leak is confirmed and stopped.

❖ If leak continues (after engine shutdown):
If the fuel quantity of the affected inner tank continues to decrease, a leak from the wing may be suspected.
