REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES
During endurance qualification tests on other AIRBUS Program Trimmable Horizontal Stabiliser Actuator
(THSA), a partial loss of No-Back Brake (NBB) efficiency was identified.
Due to similarity of design, same tests were initiated by the supplier UTAS on the Wide Body HSA
sampled from the field. Subject tests confirmed that the A300-600, A300F4-608ST and A310 HSA Part
Numbers 47142-403, 47142-413, 47142-414 and 47142-423 are also affected by this partial loss of
NBB efficiency.
Investigations have identified that a polishing and an auto-contamination by carbon particles of the
carbon friction disk surface are at the origin of this issue. This auto-contamination leads to a partial loss
of the carbon friction disks efficiency.
The partial loss of the NBB efficiency is not detect able by aircraft systems. In case of power gear train
not able to keep the ball screw in its last commended position, the loss of NBB efficiency can potentially
lead to an uncommanded movement of the THS under specific aerodynamic loads.
The phenomenon of polishing and auto-contamination of the carbon friction disks is confirmed to be an
ageing / endurance issue.
A new hard limit of the NBB carbon disks leading to HSA periodic maintenance is set to 14600 flight
cycles.
This Inspection Service Bulletin (ISB) requires to:

SERVICE BULLETIN
SUMMARY
- determine HSA current time from first installation on aeroplane and relevant FC and FH or last
NBB disks replacement whichever is later,
- check subject data against the compliance time for NBB disks replacement published through this
ISB,
- schedule the appropriate time frame for HSA removal and replacement by a serviceable unit.
After installation of serviceable HSA, operator must repeat the inspection in order to plan the next HSA
NBB disks replacement.
NOTE
: In the case the in-service history of the HSA is not known or partially missing, the
operator shall refer to the SIL 05-008 for estimation of FC and FH. The use of
conclusive maintenance records is allowed to positively determine the HSA in-service
history.
Accomplishment of this Service Bulletin permits scheduling the next HSA maintenance for NBB disks
replacement.

The partial loss of the NBB efficiency is not detectable by aircraft systems. In case of

A new hard limit of the NBB carbon disks leading to HSA periodic maintenance is set to

(2) Objective/Action
This Inspection Service Bulletin (ISB) requires to:

- determine HSA current time from first installation on aeroplane and relevant FC and
FH or last NBB disks replacement whichever is later,
- check subject data against the compliance time for NBB disks replacement

- schedule the appropriate time frame for HSA removal and replacement by a
serviceable unit.
After installation of serviceable HSA, operator must repeat the inspection in order to plan
the next HSA NBB disks replacement.
NOTE
: In the case the in-service history of the HSA is not known or partially
missing, the operator shall refer to the SIL 05-008 for estimation of

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.

3. ACCOMPLISHMENT INSTRUCTIONS
Task 276070-832-801-001 - General Vi sual Inspection of the Horizontal Stabilizer Actuator
(HSA) (FIN 35CB)
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 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 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
: The purpose of flow charts is to supplement the information given in the Procedure
and Compliance paragraphs and not to serve as the primary source for tasks or
compliance times given in this Service Bulletin.
NOTE
: This Service Bulletin is classified mandatory or expected to be classified mandatory
by an Airworthiness Directive (AD). The paragraphs 3.C. and 3.D. in these
accomplishment instructions are Required for Compliance (RC) and must be done
to comply with the AD. 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.
