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.
