HYDRAULIC LOCKING FUNCTION

MODIFICATIONS

REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES

During a post maintenance check flight, it has been identified that 5 Spoiler Servo Controls (SSC) MZ

series had lost their Hydraulic Locking Function. The failure was confirmed during shop investigations at

LIEBHERR facilities: a seal involved in the locking function was found sheared the same way in the 5

Servo Controls.

All Operators Telex (AOT) A330-27A3185 and AOT A340-27A4181 dated 04 January 2012 were

issued to request a one-time inspection of the Hydraulic Locking Function as per the new AMM Task

27-64-00-710-802 on all MZ Spoiler Servo Controls.

Currently there is no repetitive maintenance task to check the Hydraulic Locking Function of the

Spoiler Servo Controls (whatever the PN). The aim of this Service Bulletin is to introduce a repetitive

maintenance task to check the hydraulic locking function.

Due to hydraulic power generations re-configuration laws, it is more probable to lose the Blue or Yellow

pressure in the event of an engine failure at take-off (one engine pump on Blue and Yellow circuits, two

engine pumps on Green circuit).

Consequently, to preserve the low probability of a spoiler extension at take-off in case of engine

failure, and in accordance with Airworthiness objectives, the accomplishment of this Inspection Service

Bulletin (ISB) requires performing the test of the Hydraulic Locking Function as per AMM Task

27-64-00-710-802 on Spoiler Servo Controls installed on Blue and Yellow Hydraulic Circuits, that is to

say:

positions FINs 14CS1, 15CS1, 16CS1, 18CS1, 14CS2, 15CS2, 16CS2 and 18CS2 within 48 months

after aircraft first flight or within 24 months after ISB issue, whichever occurs the latest, and then at

intervals not exceeding 48 months.

SUMMARY

Accomplishment of this ISB is not required on Spoiler Servo Controls installed on Green Hydraulic

Circuit (positions 13CS1, 17CS1, 13CS2 and 17CS2).

Accomplishment of this Inspection Service Bulletin will contribute to detect possible failure of the

Hydraulic Locking Function.

3. ACCOMPLISHMENT INSTRUCTIONS

Task 275059-832-801-001 - Operational Test

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 refer to procedures

included in other AIRBUS documents. When the words ’refer to’ are used and the

operator has an accepted alternative procedure, the accepted alternative procedure

can be used. When the words ’in accordance with’ are included in the instruction,

the procedure in the AIRBUS document must be used.

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.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.

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.
