This Topic is relevant to the whole fleet

A fuel leak may be detected by either :

	the sum of the FOB and the F. USED is significantly less than the FOB at departure, or
	passenger observation (fuel spray from engine or from wing tip), or
	total fuel quantity decreasing at an abnormal rate, or
	fuel imbalance, or
	a tank emptying too fast (leak from engine or a hole in a tank), or
	a tank overflowing (due to a pipe rupture in a tank).

WHEN A LEAK IS CONFIRMED

LAND ASAP

LEAK FROM ENGINE

-THR LEVER (of affected engine)		IDLE

-ENG MASTER (of affected engine)		OFF

The Xfeed valve can now be selected open for rebalancing or to allow use of the fuel from both wings. Do not restart the engine.

LEAK NOT FROM ENGINE or LEAK NOT LOCATED

-FUEL X FEED		MAINTAIN CLOSED

The Xfeed valve must remain closed to prevent the leak affecting both sides.

-L + R INR TK		SPLIT

DESCEND TO GRVTY FUEL FEEDING CEILING
See grvty fuel feeding proc

-ENG START SEL		IGN

-ALL TK PUMPS (when gravity ceiling is reached)		OFF

In almost all cases, switching the pumps off will prevent any further loss of fuel. All pumps must be switched off, even if the leak is from one wing only, as there are some failures on one side that will result in fuel loss from the other side.

AVOID NEGATIVE G FACTOR

If one engine flames out when there is still fuel in the feeding tank :

-LEAK FROM ENGINE proc		APPLY

-ALL TK PUMPS		ON


Note : The flameout is due to air suction from a leak from the engine.

FOR LANDING

CAUTION
- Notify ATC and do not use reverse

Note : Even with a fuel imbalance of one inner tank full / one inner tank empty there is no special procedure required for approach and landing.
