Group 1-2:

1. CONCURRENT REQUIREMENTS

Refer to Data Module SB B787-A-21-00-0055-00A-932A-D, Paragraph 2., Concurrent Requirements.

2. BACKGROUND

This service bulletin gives instructions to replace the inboard and outboard Cabin Air Compressor (CAC)

modules on the left side and right side Cabin Air Conditioning and Temperature Control System (CACTCS)

packs. The current CAC module has experienced six in-service events in which electrical shorts of the motor

stator wiring burned a hole through the CAC motor stator housing. The pack bay is classified as a flammable

fluid leakage zone and the burn-through would be classified as an ignition source. The new CAC motor

housing thickness is increased to contain the arc. In addition, the CACTCS pack has reinforcements made

to support the increased weight of the new CAC. Also, a change is made to the right side CACTCS pack

CAC motor cooling ducts to help mitigate water ingress into the motor. If the service bulletin is not incorporated, the CAC may experience an electrical motor short and burn a hole in the CAC motor housing, which

could result in a fire in the pack bay.

Boeing Service Related Problem (SRP) 787 SRP-21-0208 is related to this service bulletin.

3. Reason

This service bulletin gives instructions to replace the inboard and outboard Cabin Air Compressor (CAC)

modules on the left side and right side Cabin Air Conditioning and Temperature Control System (CACTCS)

packs. The current CAC module has experienced six in-service events in which electrical shorts of the

motor stator wiring burned a hole through the CAC motor stator housing. The pack bay is classified as a

flammable fluid leakage zone and the burn-through would be classified as an ignition source. The new

CAC motor housing thickness is increased to contain the arc. In addition, the CACTCS pack has reinforcements made to support the increased weight of the new CAC. Also, a change is made to the right side

CACTCS pack CAC motor cooling ducts to help mitigate water ingress into the motor. If the service bulletin

is not incorporated, the CAC may experience an electrical motor short and burn a hole in the CAC motor

housing, which could result in a fire in the pack bay.

Boeing Service Related Problem (SRP) 787 SRP-21-0208 is related to this service bulletin.

Fleet Team Digest (FTD) 787-FTD-21-13011 is related to this service bulletin.

As part of a service bulletin validation program, this change was completed on airplanes ZA294-ZA295,

ZA536 and ZA539-ZA541 by Service Bulletin B787-81205-VB210055-00 Issue 001, dated October 17,

2014, before Issue 001 of this service bulletin. The changed completed on airplanes ZA294-ZA295, ZA536

and ZA539-ZA541 by Service Bulletin B787-81205-VB210055-00 Issue 001, dated October 17, 2014, is

equivalent to Issue 001 of this service bulletin. Airplanes ZA294-ZA295, ZA536 and ZA539-ZA541 have

the configuration of a Group 1 airplane.

12. Where the work instructions include installation of a kept part, a new or serviceable part with

the same part number can be installed as an alternative to the kept part.

13. This service bulletin includes functional test procedures for the systems changed by this service

bulletin. More functional tests can possibly be necessary in accordance with standard maintenance practices because of interruption to other airplane systems.

14. The compliance times for the actions in Step 2., Work Instructions are in Data Module SB B787-

A-21-00-0055-00A-932A-D, Paragraph 5., Compliance.

AIRCRAFT SERVICE BULLETIN
NOTE: As an option operators can install the inlet housing and flexible duct after the outboard

CAC has been installed. When the outboard CAC is being installed, it may prove difficult

to line the outboard CAC upper bracket to the 3-way mount bracket. Without the inlet

housing and flexible duct installed, it allows more space to install the fasteners required

to attach the outboard CAC upper bracket to the 3-way mount bracket. 

(11) RC - Install the modified outboard CAC Module, with CAC assembly part number 7010101H09,

onto the left CACTCS pack. Refer to UTC Aerospace Systems, Hamilton Sundstrand service bulletin

7010097-21-6 and 787 AMM 21-51-19 "Cabin Air Compressor - Left Outboard - Installation", as

accepted procedures.

NOTE: If using the ground support equipment referred to in the AMM, operators can avoid damage

back the insulation so that the insulation is not between the collar and the CAC. After the

CAC module is installed and the tool is removed, reposition and re-attach the blanket back

onto the CAC module. 

(12) RC - Do installation test of the inboard CAC. Refer to 787 AMM 21-51-19 "Cabin Air Compressor

- Left Inboard - Installation" as an accepted procedure. If steps in the installation test have not

passed, perform the corrective action and repeat the test until the test has passed.

(13) RC - Do installation test of the outboard CAC. Refer to 787 AMM 21-51-19 "Cabin Air Compressor

- Left Outboard - Installation" as an accepted procedure. If steps in the installation test have not

passed, perform the corrective action and repeat the test until the test has passed.

(14) Reidentify the CACTCS Pack. Do one of the following:

(a) For airplanes with existing left side CACTCS Pack part number 7010097H07, mark part number

7010097H08 below the CACTCS Pack identification plate. Also apply the Boeing service bulletin

number B787-81205-SB210055-00 and the UTC Aerospace Systems Hamilton Sundstrand

service bulletin number 7010097-21-6 below the CACTCS Pack identification plate. Refer to

SOPM 20-50-10 as an accepted procedure.

(b) For airplanes with existing left side CACTCS Pack part number 7010097H02 through

7010097H06, apply the Boeing service bulletin number B787-81205-SB210055-00 and the

UTC Aerospace Systems Hamilton Sundstrand service bulletin number 7010097-21-6 below

the CACTCS Pack identification plate. Refer to SOPM 20-50-10 as an accepted procedure.

(15) Close access and put the airplane back to a serviceable condition.

CONDITIONING AND TEMPERATURE CONTROL SYSTEM (CACTCS) PACK, INBOARD AND

OUTBOARD CABIN AIR COMPRESSOR (CAC) - CHANGE

NOTE: Both the inboard and the outboard CAC Module on the right Cabin Air Conditioning and Temperature Control System (CACTCS) pack must be replaced at the same time. 

NOTE: The order in which the following instructions are accomplished may be switched to simplify the

CAC change, if necessary. 

NOTE: The inlet sensor bracket is also referred to as the Right Hand (RH) CAC Pressure Sensor

Bracket in the UTC Aerospace Systems, Hamilton Sundstrand service bulletin 7010098-21-6.
