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.

Boeing Service Related Problem (SRP) 767-SRP-38-0063 is related to this service bulletin.

Boeing Service Related Problem (SRP) 767-SRP-38-0074 is related to this service bulletin.

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.

ALERT ALERT
Revision 1 is 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 is 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.
