SUMMARY
This summary is for information only and is not approved for modification of the aircraft.
A. MODIFICATIONS
MODIFICATION CLASSIFICATION
MAJOR None
MINOR 209295S35581
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.
B. REASON
(1) History
A330 aircraft powered by PW4164, PW4168, PW4168A, PW4164-1D, PW4168-1D,
PW4168A-1D and PW4170 engines and in pre-MOD 53623 configuration are currently
equipped with part number (PNR) 72A100-701 or PNR 72A100-703 Lower Aft Pylon
Fairing (LAPF). These LAPF include PNR 72A100-425 firewalls, which are subject to
mandated DVI for crack inspection every 2 years, as requested by Airworthiness
Directive (AD) F-2004-028 R2.
(2) Objective/Action
This Service Bulletin (SB) is issued to advise all operators of A330 aircraft as
mentioned above of the issue of PRATT & WHITNEY Service Bulletin PW4G-100-A54-12.
This Service Bulletin recommends replacing PNR 72A100-703 LAPF (including PNR
72A100-425 firewalls) by new PNR 72A100-713 LAPF (including new 72A100-627
firewalls). A330 aircraft equipped with pre-MOD 53623 PNR 72A100-701 LAPF shall
apply PW VSB PW4G-100-54-1 first, in order to modify PNR 72A100-701 into PNR
72A100-703, before applying the current SB A330-54-3050.
(3) Advantages
The accomplishment of this Service Bulletin will allow terminating Airworthiness
Directive pending at the time of release of this SB.

WARNING: MAKE SURE THAT YOU OBEY ALL THE WARNINGS AND ALL THE CAUTIONS
INCLUDED IN THE REFERENCED PROCEDURES.
CAUTION: ALWAYS OBEY THE PRECAUTIONS THAT FOLLOW TO KEEP ELECTRICAL
WIRING IN A SATISFACTORY CONDITION (ELECTRICALLY AND MECHANICALLY
SERVICEABLE). WHEN YOU DO A MAINTENANCE WORK, REPAIRS OR
MODIFICATIONS, ALWAYS KEEP ELECTRICAL WIRING, COMPONENTS AND
THE WORK AREA AS CLEAN AS POSSIBLE. TO DO THIS:
- PUT PROTECTION, SUCH AS PLASTIC SHEETING, CLOTHS, ETC., AS
NECESSARY ON WIRING AND COMPONENTS.
- REGULARLY REMOVE ALL SHAVINGS, UNWANTED MATERIAL AND
OTHER CONTAMINATION.
THESE PRECAUTIONS WILL DECREASE THE RISK OF CONTAMINATION AND
DAMAGE TO THE ELECTRICAL WIRING INSTALLATION.
IF THERE IS CONTAMINATION, REFER TO ESPM Ref. ESPM 20-55-00.
NOTE: The accomplishment instructions of this Service Bulletin include procedures given in
other documents or in other sections of the Service Bulletin. When the words “refer to”
are used and the operator has a procedure accepted by the local authority he belongs to,
the accepted alternative procedure can be used. When the words “in accordance with”
are used then the given procedure must be followed.
NOTE: The access and close-up instructions, not comprising return to service tests, in this
Service Bulletin do not constitute or affect the technical intent of the Service Bulletin.
Operators can therefore, as deemed necessary, omit or add access and/or close-up steps
to add flexibility to their maintenance operations as long as the technical intent of the
Service Bulletin is met within the set parameters.
NOTE: Manual titles given in the accomplishment instructions are referred to by acronyms. Refer
to paragraph 1.J., References, for the definition of acronyms.
NOTE: This Service Bulletin contains the instructions for the on-aircraft maintenance necessary
to ensure the continued airworthiness of the aircraft.
For any deviations to the instructions, contact AIRBUS for further instructions and
approval.
