CFM56-5C – Advanced Engine Interface Vibration Monitoring (AEIVM) system

upgrade: software introduction (19-12-7200-01)

Reference: CFM56 Fleet Highlites article (18-01-7200-03), January 2018, “AEIVM System upgrade”

This article informs CFM56-5C operators that the new CFM56-5Cpowered-A340

Advanced Engine Interface Vibration Monitoring Unit

(AEIVMU) algorithm is available on the Meggitt portal. Refer to the

January 2018 Fleet Highlites article (link) for background.

Background

The AEIVMU was introduced on the Airbus A340 in June 2010 by

Airbus SB A340-73-4018 to help detect no.3 and no.4 bearing

degradation. Three algorithms (4R, 4L and 3B) analyze the vibration

broadband during various flight phases and trigger an alert (ACMS

report 34) when a signature surpasses a specified threshold. The

new 4L+ algorithm is being added to the existing algorithms to

improve detection by performing an analysis during the sub-idle

start phase.

CFM, Meggitt and Airbus have conducted lab tests and flight tests to

validate this new software configuration.

Please contact Meggitt Technical Publication Department :

techpubs@ch.meggitt.com to obtain SB 201-73-009 and a

Username/Password required to download the new version of

Ground Support Software and associated firmware files.

The link on the Meggitt download site to obtain the GSS and the

new firmware to update the AEIVMU is as follows:

https://mymeggittsupport.com/

• Then click on “Technical Support “tab (Figure 1)

Figure 1

• Next step, login at the bottom of the page to get the files (Figure 2)

An “in service evaluation” (ISE) was conducted for one year.

Feedback from this ISE was used to develop improvements that have

been incorporated into the new algorithm (4L+).

Note that with the new configuration, the process for downloading

and reporting AEIVMU alarms does not change. Following an

AEIVMU alarm, a report 45 will be automatically printed from the

MCDU. Then, a download is required to send the report to CFM for

processing the signal and analyzing the data.

TSM task 77-32-00-810-819-A/820-A download procedure has to

be done before replacing an engine to avoid data reset.

Figure 2

Downloading the AEIVMU software

Meggitt issued Service Bulletin SB 201-73-009 (November 2017) to

introduce the availability of a new set of improved algorithms to be

loaded onto the Advanced Engine Interface and Vibration Monitoring

Units (Advanced EIVMUs) with PN 271-201-011-501 that are

installed on the Airbus A340 aircraft with CFM56-5C engines.

• Use laptop and specific Meggitt cable: PN 984-415-000-011

• Load GSS 3.0.5 software from Meggitt web site (on request) and

install it on laptop

• Upload Algorithms to AEIVMU with GSS 3.0.5, laptop and cable as

described in the Service Bulletin accomplishment instructions

CFM56-All – Hexavalent Chromium on engine parts (19-12-7200-03)

CFM has learned that some engine parts have been observed with a

residue containing hexavalent chromium (Cr(VI)). The residue has

primarily been found at shop level but can also be found during line

maintenance. This article provides the status of the investigation

and offers recommendations if a residue is found on engine

hardware.

Recommendations

CFM recommends that maintenance personnel comply with local

regulatory guidelines, including wearing eye/face protection and

disposable gloves/clothing when handling parts to minimize worker

exposure.

Approved penetrant and consumables oils should be applied to

affected areas prior to removing the residue by scraping and/or

wiping.

Figure 1: Photo of an engine component exhibiting a residue that may

contain hexavalent chromium

What is hexavalent chromium: Cr(VI)?

Hexavalent chromium, also referred to as Cr(VI), is a group of

substances that contain the metallic element chromium (Cr) in its

positive 6 valence (hexavalent) state. It is a product used in a variety

of industrial applications, including stainless steel

production/welding, thermal cutting, chrome plating, painting, and

coating processes.

Exposure to high levels of airborne, oral or dermal Cr(VI) compounds

is associated with an increased health hazard, and should be avoided.

Investigation of Cr(VI) findings

CFM is investigating which engine components and product lines are

potentially affected, with the following findings:

• The presence of a residue that may contain Cr(VI) has been

observed on various engine parts across engine programs.

• The residue is not found on every engine part.

• Not every engine part that has been found with a residue has tested

positive for Cr(VI).

CFM has determined that the Cr(VI) residue is a surface phenomenon

only and has no impact on bulk material properties.

The root cause investigation of the formation of Cr(VI) is ongoing.

Initial findings indicate a chemical reaction between some assembly

aids and environmental dust containing MgO, CaO, Ca(OH)2 with

chromium occurs at the surface of metallic parts also containing

chromium (Ni, Co and Fe based alloys) at engine operating

temperatures. Depending on the composition of environmental dust,

formation of Cr(IV) can continue. Industrial Hygiene (IH) and

handling precautions should be followed in order to minimize

airborne exposure to Cr(IV) during engine maintenance.

If potentially contaminated component parts are to be moved or

transported, take precautions to minimize direct contact or release

of the residue during handling and transportation. All such parts

should be placed in plastic bags or securely wrapped in plastic.

Shipping and marking must be in compliance with regulatory

requirements.

Documentation

CFM is creating/revising applicable manuals to include:

• New SPM (Standard Practices Manual) procedure to aid in the

identification and handling of parts with residue potentially

containing Cr(VI).

• The following warning in the Engine Shop Manual front matter

introduction section and other applicable manuals that describes

environmental, health and safety precautions required for moving,

touching, replacing or discarding hardware with possible Cr(VI)

residue.

* Note that revisions to the front matter introduction cannot be

released as an Incremental Change; therefore, the revisions will

be incorporated during the normal engine manual release cycle.

WARNING:

THIS ENGINE, MODULE AND ATTACHING PARTS MAY HAVE RESIDUE

PRESENT ON THEIR SURFACES THAT MAY CONTAIN HEXAVALENT

CHROMIUM. WHEN YOU WORK WITH THIS ENGINE YOU MUST OBEY THE

PRECAUTIONS THAT FOLLOW.

• YOU MUST OBEY ALL APPLICABLE ENVIRONMENTAL, HEALTH AND

SAFETY REGULATORY PRECAUTIONS BEFORE YOU MOVE, TOUCH,

REPLACE OR DISCARD HARDWARE THAT CONTAINS HEXAVALENT

CHROMIUM.

• HEXAVALENT CHROMIUM MAY CAUSE ADVERSE HEALTH EFFECTS

IF INGESTED, INHALED, OR CONTACTED WITH SKIN AND REQUIRES

CARE IN HANDLING.

- AVOID CONTACT WITH SKIN, EYES AND MUCUS MEMBRANES.

- AVOID INHALATION OR INGESTION OF RESIDUE.

- WEAR DISPOSABLE NITRILE GLOVES AND EYE PROTECTION

WHENEVER INSPECTING OR HANDLING PARTS WITH THE

SUSPECTED RESIDUE.

- IN CASE OF CONTACT, IMMEDIATELY IRRIGATE AFFECTED AREA

WITH RUNNING WATER.

- IF CONTACT IS SEVERE, OBTAIN MEDICAL ATTENTION.

Summary

Residue potentially containing hexavalent chromium has been found

on some engine parts. Exposure to high levels of airborne, oral or

dermal Cr(VI) compounds is associated with an increased health

hazard, and should be avoided. Hazardous material cautions and

environmental, health & safety protocols compliant with applicable

regulations are required when encountered.

If you have further questions or concerns, please submit an inquiry

through the myCFM portal.

CFM56-All – Minutes of the TechPubs Customer call – Upcoming TechPubs Customer

Forum (19-12-7200-06)

CFM hosts a periodic TechPubs Customer Call that is available to all TechPubs users. The calls offer direct discussion between the CFM technical

documentation team and CFM Tech Pubs users. Summaries of these calls are provided in Fleet Highlites.

In order to provide the best support for myCFM portal users, the

myCFM TechPubs team held the 15 th TechPubs customer call on

December 12, 2019 to present the latest developments and news

regarding CFM Technical Documentation.

CFM56-5B/CFM56-7B revision schedule change

(reminder)

Currently, all CFM56 engine programs except the CFM56-5B and the

CFM56-7B have one global revision per year for technical

publications.

Beginning next year, the revision cycle for the CFM56-5B and the

CFM56-7B engine programs will be reduced from two revisions per

year to one revision per year. Figure 1 shows the CFM56-5B and

CFM56-7B revision schedule for 2020:

Moreover, the ICs packages, which are cumulative, provide the

following benefits:

• Packages are smaller in size than a global revision

• Faster download

• Possibility to select the documents you need

• Same files as for a revision (Raw data: XML, SGML, illustrations,

PDF, etc.…)

Please note that

• For the myTechPub online viewer users: the technical

documentation is always up-to-date (updates included

automatically).

• For the offline viewer users: users need to download the update

packages to be always up-to-date. using the myCFM portal

myDownload widget.

Incremental Changes delivery planning

Figure 1: CFM56-5B and CFM56-7B revision schedule for 2020

The TMI (Technical Manual Index) was updated on November 1, 2019

to reflect these changes. Users are invited to check it as needed:

https://www.cfmaeroengines.com (section “Support” → scroll down

until the section, “Technical Manuals,” then click on”CFM56 Engine

Manuals Index”).

CFM provides updates between two revisions called Incremental

Changes (ICs), when necessary, according to the IC publication

planning below.

• ESM & CMM ICs are published weekly according to the following

schedule (Figure 2):

Please note that extra publications may be published for urgent ICs.

CFM will continue to update the CFM56-5B and CFM56-7B

documentation by Incremental Change, when necessary, between

revisions.

CFM encourages users to subscribe to the myCFMportal Incremental

Changes notifications to remain informed of the latest CFM56-5B and

CFM56-7B Incremental Change releases.

For more details on the myCFM portal notifications, please refer to

the September 2019 Fleet Highlites article “CFM56-All –

myCFMportal notifications news; 2020 TechPubs Customer Forum

survey (19-09-7200-03).”

Figure 2: ESM global IC delivery planning

• EIPC ICs are published according to the following schedule, on the

same day as an ESM update (Figure 3).

Incremental Change (IC): I see, You see, We all use IC!

CFM strongly recommends users to use the ICs in order to

• Be always up to date with the CFM technical documentation, prior to

the next revision

• Get the latest criteria

• Get the latest procedures

• Save time and resources implementing earlier new procedures

• No need to wait for the next revision
