TITLE: POWER PLANT - GENERAL - WRONG AFT MOUNT TORQUE VALUE

FOR ENGINES CFM56-5A IN AMM 71-00-00-400-040-A01

REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES

In the May 2013 AMM revision, an incorrect AFT pylon bolt torque value was introduced in AMM Task

71-00-00-400-040-A01 "Installation of the Power Plant with Engine Positioner TWW 75E" used only for

CFM56-5A engine model.

The correct torque value to be mentioned in this AMM Task should be 65.08-78.64 m.daN (480-580

lbf.ft) whereas it mentioned 43.39-47.45 m.daN (320-350 lbf.ft) in the May 2013 AMM revision.

This AMM Task has been corrected to reflect the correct torque value for AFT engine mounts in the

May 2014 AMM revision.

Pending availability of the AMM correction, a Temporary Revision (TR) 71-030 with correct information

is available since Mar 14/14.

The aim of this Service Bulletin is to re-torque the affected bolts at correct level to assure the

proper assembly performance and comply with current fatigue and damage tolerance certification

requirements.

Accomplishment of this Service Bulletin will contribute to avoid pylon bolts and beam holes fretting

damages and joint separation which would decrease their fatigue life and make the pylon bolts noncompliant with certified maintenance program.

(5) Configuration definition

**CONF 001

Config. 001 is valid for all the aircraft given in the effectivity of this Service Bulletin as a

standard configuration.

(6) Material Effectivity

No Material Set

B. CONCURRENT REQUIREMENTS

None

C. REASON

(1) History

In the May 2013 AMM revision, an incorrect AFT pylon bolt torque value was introduced

in AMM Task 71-00-00-400-040-A01 "Installation of the Power Plant with Engine

Positioner TWW 75E" used only for CFM56-5A engine model.

The correct torque value to be mentioned in this AMM Task should be 65.08-78.64

m.daN (480-580 lbf.ft) whereas it mentioned 43.39-47.45 m.daN (320-350 lbf.ft) in the

May 2013 AMM revision.

This AMM Task has been corrected to reflect the correct torque value for AFT engine

mounts in the May 2014 AMM revision.

Pending availability of the AMM correction, a Temporary Revision (TR) 71-030 with

correct information is available since Mar 14/14.

(2) Objective/Action

The aim of this Service Bulletin is to re-torque the affected bolts at correct level to

assure the proper assembly performance and comply with current fatigue and damage

tolerance certification requirements.

(3) Advantages

Accomplishment of this Service Bulletin will contribute to avoid pylon bolts and beam

holes fretting damages and joint separation which would decrease their fatigue life and

make the pylon bolts non-compliant with certified maintenance program.

(4) Operational/Maintenance Consequences

None

D. DESCRIPTION

To accomplish this Service Bulletin it is necessary to :

E. COMPLIANCE

(1) Classification

RECOMMENDED: Service Bulletin recommended to be accomplished to prevent

significant operational disruptions.

(2) Accomplishment Timescale

This Service Bulletin has been classified Recommended. It is expected that an

Airworthiness Directive (AD) published by the European Aviation Safety Agency (EASA)

will be issued to change this classification to Mandatory. It is anticipated that the AD will

confirm the threshold 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

Organization Approval No. EASA.21J.031.

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 711063-832-801-001 - Inspection of the AFT Engine Mount Pylon Bolts (FINs 1000EM1

and 1000EM2)

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 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: 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.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.
