B. REASON
(1) History
The Trimmable Horizontal Stabilizer Actuator (THSA) has a fail-safe design: each
attachment, upper and lower, has two load paths, a normally loaded primary load
path and a secondary load path, which is only engaged in case of primary load path
rupture.
When the secondary load path is engaged, the design purpose was to generate a stall
of the unit by friction and to detect it by the position monitoring.
It has been demonstrated by test that the upper secondary load path may not stall
correctly in some cases.
Hence a new device has been developed, called Load Sensing Device (LSD) and
manufactured by UTC Aerospace, which aims at detecting the engagement on the
secondary load path.
(2) Objective/Action
This Service Bulletin details instructions for installation and activation of the LSD,
following the wiring provisions embodied by AIRBUS at aircraft production.
(3) Advantages
Accomplishment of this Service Bulletin will allow to detect upper secondary load
path engagement. The periodic detailed inspection of THSA upper attachments for
secondary load path loading will be preserved.

B. CONCURRENT REQUIREMENTS
Accomplishment of this Service Bulletin requires the prior or simultaneous accomplishment
of this Service Bulletin:
Service Bulletin(s) Modification(s)
Ref. SB A330-27-3237  
NOTE: Service Bulletin No. Ref. SB A330-27-3237 (FLIGHT CONTROLS - TRIMMABLE
HORIZONTAL STABILIZER (THS) HYDRAULIC ACTUATION - INTRODUCE WIRING
PROVISION FOR LOAD SENSING DEVICE (LSD) RETROFIT) is a concurrent
requirement if MOD No. 205978S33729 has not been embodied before delivery.
C. REASON
(1) History
The Trimmable Horizontal Stabilizer Actuator (THSA) has a fail-safe design: each
attachment, upper and lower, has two load paths, a normally loaded primary load
path and a secondary load path, which is only engaged in case of primary load path
rupture.
When the secondary load path is engaged, the design purpose was to generate a stall
of the unit by friction and to detect it by the position monitoring.
It has been demonstrated by test that the upper secondary load path may not stall
correctly in some cases.
Hence a new device has been developed, called Load Sensing Device (LSD) and
manufactured by UTC Aerospace, which aims at detecting the engagement on the
secondary load path.
(2) Objective/Action
This Service Bulletin details instructions for installation and activation of the LSD,
following the wiring provisions embodied by AIRBUS at aircraft production.
(3) Advantages
Accomplishment of this Service Bulletin will allow to detect upper secondary load
path engagement. The periodic detailed inspection of THSA upper attachments for
secondary load path loading will be preserved.
(4) Operational/Maintenance Consequences
The Operational/Maintenance Consequences of this Service Bulletin are covered by
the update of the affected publications detailed in "PLANNING INFORMATION".
D. DESCRIPTION
T o accomplish this Service Bulletin it is necessary to:
(1) Modification to the THSA by Installation and Activation of the Electrical Load
Sensing Device (ELSD)
(a) T ask set A330-A-27-XX-3234-01000-93AA-A Modification to the THSA by
Installation and Activation of the Electrical Load Sensing Device (ELSD)
1 Remove the T wo Fail Safe Secondary Upper Bolts of the THSA FIN (1CS)
2 Install the ELSD FIN (58CS) on the THSA FIN (1CS)

4 Modify the Circuit Breaker FIN (59CS) in the APU Control Box FIN (5000VE)
E. COMPLIANCE
(1) Classification
MANDATORY: Service Bulletin must be accomplished.
(2) Accomplishment Timescale
This Service Bulletin has been classified Mandatory by the issue of an Airworthiness
Directive (AD) published by the European Aviation Safety Agency (EASA). The AD must
be used as the reference document for the mandated accomplishment timescale.
F. APPROVAL
The technical content of this document is approved under the authority of the Design
Organisation Approval ref. EASA.21J.031.
If an aircraft listed in the applicability 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
CONF 001
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.

Modification to the THSA by Installation and Activation of the Electrical Load Sensing Device
(ELSD)
WARNING: MAKE SURE THAT YOU OBEY ALL THE WARNINGS AND ALL THE CAUTIONS
INCLUDED IN THE REFERENCED PROCEDURES.
WARNING: MAKE SURE THAT THE SAFETY DEVICES AND THE WARNING NOTICES ARE IN
POSITION BEFORE YOU START A TASK ON OR NEAR:
- THE FLIGHT CONTROLS
- THE FLIGHT CONTROL SURFACES
- THE LANDING GEAR AND THE RELATED DOORS
- COMPONENTS THAT MOVE.
MOVEMENT OF COMPONENTS CAN KILL OR CAUSE INJURY TO PERSONS
AND/OR CAN CAUSE DAMAGE TO THE EQUIPMENT.
WARNING: MAKE SURE THAT THE TRAVEL RANGES OF THE FLIGHT CONTROLS ARE
CLEAR.
MOVEMENT OF FLIGHT CONTROLS CAN CAUSE INJURY TO PERSONS AND/OR
DAMAGE.
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 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 is classified mandatory or expected to be classified mandatory by
an Airworthiness Directive (AD). The paragraphs 3.C. and 3.E. in these accomplishment
instructions are Required for Compliance (RC) and must be done to comply with the AD.
T o allow more flexibility, the rule "refer to" and "in accordance with" will apply to these
paragraphs 3.C. and 3.E. Other paragraphs are recommended and may be deviated from,
done as part of other actions or done with accepted methods different from those given
in the Service Bulletin, as long as the RC paragraphs can be done and the aircraft can be
put back into a serviceable condition.
