USE AS RQRD
If the leak stops, the crossfeed valve can now be opened to re-balance fuel quantity,
or to enable
use of fuel from both wings. Do not restart the engine.
LEAK FROM ENGINE/PYLON NOT CONFIRMED or LEAK NOT
LOCATED:
Stop any fuel transfer, and then monitor the depletion rate of each inner tank, to
determine if the leak
is from an engine or a wing (case 1), or from the Center tank or the APU feeding line
(case 2).
FUEL X FEED......................................................................................................
MAINTAIN CLOSED
The crossfeed valve must remain closed to prevent the leak from affecting both sides.
CTR TK PUMP
1+2........................................................................................................................OFF
Each engine is fed via its associated inner tank only.
INNER TANK FUEL
QUANTITIES....................................................................................... MONITOR
Monitor the depletion rate of each inner tank.
CASE 1: IF ONE INNER TANK DEPLETES FASTER THAN THE OTHER
BY AT LEAST
300 kg (660 lb ) IN LESS THAN 30 min:
An engine leak may still be suspected. Therefore:
THR LEVER (engine on leaking
side).................................................................................... IDLE
ENG MASTER (engine on leaking
side)................................................................................. OFF
CTR TK PUMP
1+2...................................................................................................................ON
FUEL LEAK....................................................................................................................
MONITOR
If leak stops:
If the inner tank fuel quantity of the affected side stops decreasing, the engine leak is
confirmed and stopped.
FUEL X FEED................................................................................................. USE AS
RQRD
The crossfeed valves can now be opened to re-balance fuel quantity, or to enable use
of
fuel from both wings. Do not restart the engine.
If leak continues (after engine shutdown):
The inner tank fuel quantity of the affected side continues to decrease. If the leak has
not
stopped after engine shut down, a leak from the wing may be suspected.
ENGINE
RESTART................................................................................................CONSIDER
CAUTION Do not apply the FUEL IMBALANCE procedure. Approach and landing
can be
done, even with one full wing/one empty wing.

FUEL LEAK (Cont'd)
CASE 2: IF BOTH INNER TANKS DEPLETE AT A SIMILAR RATE:
A leak from the Center tank or the APU feeding line may be suspected.
If fuel smell in the cabin:
APU (if
ON)....................................................................................................................... OFF
This prevents additional fuel loss through the APU feeding line.

DETERMINE GRAVITY FEED CEILING:
Consult the following table to determine the flight altitude limitation.
Flight conditions at time of gravity feeding Gravity feed ceiling
Flight time above FL 300 more than 30 min
(Fuel deaerated)
Current FL(1)
Flight time above FL 300 less than 30 min
(Fuel non-deaerated)
FL 300(1)
Aircraft flight level never exceeded FL 300
(Fuel non-deaerated)
FL 150(1), or 7 000 ft above takeoff airport, whichever is higher
(1) For JET B, gravity feed ceiling is FL 100 in all cases.
DESCEND TO GRVTY FEED CEILING (if applicable).
