ENG FUEL SYS CONTAMINATION
This procedure must be applied if a fuel contamination has been confirmed by the application of the SUSPECTED ENG FUEL SYS CONTAMINATION procedure. This fuel contamination may result, in the worst case, in a loss of engine thrust control. This procedure aims at maintaining the thrust on one engine while minimizing the thrust changes on the other, in order to prevent contaminant from blocking the mechanical devices of engine thrust regulation.
In case of ENG 1(2) CTL SYS FAULT on only one engine:
– Set and maintain the thrust on the engine affected by the ECAM
caution
– Minimize the thrust changes on the engine not affected by the
ECAM caution
In case of ENG 1 and 2 CTL SYS FAULT (both engines affected by the ECAM caution):
– Set and maintain the thrust on the first engine affected by the ECAM caution
– Minimize the thrust changes on the second engine affected by the ECAM caution
WHEN FUEL CONTAMINATION IS CONFIRMED
LAND ASAP – A/ THR ..........................................................KEEP OFF
– MAN THR (ECAM affected or 1st ECAM affected engine) ....................................................... SET and MAINTAIN
Set the thrust (N1) on the applicable engine according to the following table. This thrust should be maintained until final approach.

! FOR CRUISE
– MAN THR (Non ECAM affected or 2nd ECAM affected
engine)..................................................SET AS RQRD
Minimize thrust changes on the applicable engine.
! DESCENT
– MAN THR (Non ECAM affected or 2nd ECAM affected
engine).................................................................. IDLE – SPD BRK......................................................AS RQRD Manage the descent using speed brakes as necessary
so as to perform a level-off at approximately 3 000 ft
AGL and 20 nm from the runway threshold.
– ATC.................................................................NOTIFY
Notify ATC to ensure runway availability for landing. - cont’d -
