- for IAE engines (Ref. AMM TASK 28-16-00-790-00100).
(7) If the reported fuel leakage occurred for:
(a) The first time: 1 Make an entry in the aircraft technical log to make a record
_
of this procedure.
2 Return the aircraft to service.
_
3 Make a record in the aircraft log book for the flight crew,
_
during the next flight, to:
a Monitor and record the initial FOB, the final or current
_ FOB and the FU for fault confirmation of the original fuel leak.
b Compare the initial FOB with the sum of the final FOB and
_ FU for calculated signs of a fuel leak (discrepancy).
(b) The second time:
1 Do the step (1) again in more detail.
_ NOTE : Make sure that good lighting is available.
____ 2 Do the steps (4) thru (6) again in more detail.
_
3 Troubleshoot the data supplied by the systems that follow:
_
- FOB - FQIS Chap. 28-42-00
- FU - FFIS Chap. 73-31-00.

R General Background Data
R
R In the Flight Warning Computer (FWC) standards H1E2, H2E2 (or earlier)
R the related logic diagrams for the ECAM FUEL warnings that follow do not
R include an A321 logic input:
R - FUEL-LEFT WING TANK OVERFLOW -A321 (See LOGIC IDENT 1.28.582)
R - FUEL-RIGHT WING TANK OVERFLOW -A321 (See LOGIC IDENT 1.28.584).
R NOTE : The applicable logic diagrams can be found in the ECAM SYSTEM____
R LOGIC BOOKs (ECLB), as described in AIRBUS SIL 31-017, (paper
R copies in three binders).
R Thus it is possible that a failure in a SDAC can trigger a (spurious)
R ECAM warning for an item of equipment, or system, that is not installed
R in that standard (type) of single aisle aircraft (Ref. OEB 148-2).
R
R With the introduction of Flight Warning Computer (FWC) standards H1E3,
R H2E3 or later, the same logic diagrams (as referred to above) were given
R a A321 logic input.
