CONCURRENT REQUIREMENTS
None.
BACKGROUND
Accomplishment of this service bulletin will make sure that the potable water system couplings in section 41 do
not leak onto electrical equipment. If this service bulletin is not done, an uncontrolled water leak from a defective
potable water system coupling could cause the Main Equipment Center (MEC) Line Replaceable Units (LRU's)
to become wet. Wet Main Equipment Center (MEC) Line Replaceable Units (LRU's) could result in an electrical
short and potential loss of several functions essential for safe flight.
An operator reported problems with the Engine Indication and Crew Alerting System (EICAS) display system
during flight. An investigation of the event determined that it was caused by a water leak from a fractured plastic
potable water coupling. Boeing analysis of all 767 models, based on delivered configurations, identified nine
possible coupling locations as being near enough to electrical LRU's to cause a potential problem if water leaked
from them. To reduce this risk, plastic couplings have now been made one way replaceable by metal couplings.
Plastic couplings were delivered on airplanes between line numbers 534 and 890. Plastic couplings have also
been listed as two-way interchangeable with metal couplings applicable to 767 passenger airplanes up to line
number 1062, thus, the changes in this service bulletin are applied to line numbers 534 thru 1062. Any plastic
couplings found in the identified locations will be replaced with metal couplings. In addition, to further protect
LRU's, spray shrouds, used on all new production airplanes, will be installed on operational airplanes to cover
the identified couplings, to direct any leakage away from electrical equipment.
This service bulletin gives instructions to inspect and replace plastic potable water couplings with metal couplings
in the identified locations in Section 41. In addition, spray shrouds and shields are installed to cover the identified
couplings. Installation of new metal couplings will reduce the chance of uncontrolled water leakage and the
spray shrouds will protect essential electrical systems should a leak occur.

2. Spares Affected
None.
B. Concurrent Requirements
None.
C. Reason
Accomplishment of this service bulletin will make sure that the potable water system couplings in section
41 do not leak onto electrical equipment. If this service bulletin is not done, an uncontrolled water leak
from a defective potable water system coupling could cause the Main Equipment Center (MEC) Line
Replaceable Units (LRU's) to become wet. Wet Main Equipment Center (MEC) Line Replaceable Units
(LRU's) could result in an electrical short and potential loss of several functions essential for safe flight.
An operator reported problems with the Engine Indication and Crew Alerting System (EICAS) display
system during flight. An investigation of the event determined that it was caused by a water leak from
a fractured plastic potable water coupling. Boeing analysis of all 767 models, based on delivered
configurations, identified nine possible coupling locations as being near enough to electrical LRU's to
cause a potential problem if water leaked from them. To reduce this risk, plastic couplings have now
been made one way replaceable by metal couplings. Plastic couplings were delivered on airplanes

between line numbers 534 and 890. Plastic couplings have also been listed as two-way interchangeable
with metal couplings applicable to 767 passenger airplanes up to line number 1062, thus, the changes
in this service bulletin are applied to line numbers 534 thru 1062. Any plastic couplings found in the
identified locations will be replaced with metal couplings. In addition, to further protect LRU's, spray
shrouds and shields, used on all new production airplanes, will be installed on operational airplanes
to cover the identified couplings, to direct any leakage away from electrical equipment.
This service bulletin gives instructions to inspect and replace plastic potable water couplings with metal
couplings in the identified locations in Section 41. In addition, spray shrouds and shields are installed
to cover the identified couplings. Installation of new metal couplings will reduce the chance of uncontrolled
water leakage and the spray shrouds and shields will protect essential electrical systems should a leak
occur.

Revision 1 was sent to make some minor text changes in the Work Instructions, correct some part
numbers in the Material Information section and to add reference to FAA NPRM 2014-NM-059-AD in
the Compliance section.
Revision 2 was sent to remove Boeing Converted Freighter (BCF) airplanes from Groups 1 and 12 of
this service bulletin effectivity as these airplanes are not affected by this change. In addition, more work
is added for Groups 1-3, 9, and 11 airplanes that have already accomplished this service bulletin to do
a general visual inspection of the spray shield at location 4 to make sure it is manufactured with two
slits and is correctly installed. Configurations 1 and 2 are also added to Groups 1-3, 9, and 11 to
separate airplanes that have already accomplished previous releases of this service bulletin from those
that have not. Revision 2 also adds a new Appendix which shows an illustration of a correctly
manufactured spray shield and changes some figure illustrations to clarify the correct installation of
the spray shields.
Revision 3 is sent to change the work instructions for Group 11 Configuration 1, add more work for
Group 11 Configuration 2 and to add Group 11 Configuration 3. Group 11 work instructions are changed
to remove three hose assemblies and to install four new hose assemblies between location 6 and
location 9. Airplane variable numbers VL871, VN654, VN655, VN656, VN676 and VS316 are added
to new Group 14 and Airplane variable numbers VF251, VR107, VR108 and VR109 are added to new
Group 15. A new figure for airplanes in Groups 4, 5, 12 and 15 is added to give an alternative installation
of the spray shield at location 5.

F. Approval
This service bulletin was examined by the Federal Aviation Administration (FAA). The changes specified
in this service bulletin comply with the applicable regulations and are FAA approved, as well as European
Aviation Safety Agency (EASA)/Joint Aviation Authorities (JAA) approved for all EASA/JAA approved
airplanes listed in the service bulletin effectivity. This service bulletin and its approval were based on
the airplane in its original Boeing delivery configuration or as modified by other approved Boeing
changes.
If an airplane has a non-Boeing modification or repair that affects a component or system also affected
by this service bulletin, the operator is responsible for obtaining appropriate regulatory agency approval
before incorporating this service bulletin.
G. Manpower
The table below shows an estimate of the task hours necessary to do this inspection and change for
each airplane. This estimate is for direct labor only, done by an experienced crew. Adjust the estimate
with operator task hour data if necessary. The estimate does not include lost time. These are some
examples of lost time:
