NOTE
: As per EASA IR 21, a minor change is one that has no appreciable effect on the
mass, balance, structural strength, reliability, operational characteristics affecting the
airworthiness of the product. All other changes are major changes.
REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES
As a result of vendor testing, it has been shown that under specific circumstances, with a combination
of conditions, the fuel pump thermal fuses may not open in time to prevent fuel pump overheat and
subsequent in tank ignition. As a result a new standard of fuel pump motor has been developed with
improved thermal protection. The new standard restores compliance with the SFAR88 policy.
This Service Bulletin is published to advise all operators of A300 series aircraft of the issue of ZODIAC
Service Bulletin No. 2052C23-28-02.
This Service Bulletin installs the new standard of fuel pumps to all positions.
Fuel pumps can be modified to the latest standard by two means:
- Return to vendor for exchange or modification
- Modify in accordance with ZODIAC Service Bulletin No. 2052C23-28-02.
Accomplishment of this Service Bulletin will improve the fuel pump thermal protection and fully restore
compliance to the SFAR88 policy. Full embodiment of this modification is expected to terminate the
repeat inspection requirements of AD 2013-0163.

(1) Classification
MANDATORY: Service Bulletin must be accomplished.
(2) Accomplishment Timescale
This Service Bulletin has been classified Mandatory. It is expected that an Airworthiness
Directive (AD) published by the European Av iation Safety Agenc y (EASA) will be issued
to confirm this classification. It is anticipated that the AD will confirm the threshold of 72
months from Service Bulletin issuance date given but reference should be made to the
AD for confirmation of the mandated accomplishment timescale.
F. APPROVAL
The technical content of this document is approved under the authority of Design
Organisation Approval No. EASA.21J.031.

SERVICE BULLETIN
If an aircraft listed in the effectivity has a modification or repair embodied that is not of
AIRBUS origin, and which affects the content of this Service Bulletin, the operator is
responsible for obtaining approval by its airworthiness authority for any adaptation necessary
before incorporation of the Service Bulletin.
G. MANPOWER
The manpower estimates given in this Service Bulletin are based on the direct labor cost to
do the work. These estimates assume that the work will be done by experienced personnel,
and may need to be revised upwards to suit operator’s circumstances. The estimates do not
include the time to prepare, plan or inspect the work. Manufacture and procurement of parts
and tools, drying times for paints, sealants, etc., and general administration work are also not
included.
