# 767 Service Bulletin ALERT Summary Number: 767-38A0073 Original Issue: November 12, 2013 Revision 2: August 10, 2015 ATA System: 3810 3071 SUBJECT: WATER/WASTE - Potable - Section 41 Potable Water Couplings Inspection and Replacement and Spray Shroud Installation THIS BULLETIN IS SENT TO THE OPERATORS OF RECORD OF THE AIRPLANES SHOWN IN PARAGRAPH 1.A., EFFECTIVITY. IF AN AIRPLANE HAS BEEN LEASED OR SOLD, SEND THIS SERVICE BULLETIN TO THE NEW OPERATOR. IF APPLICABLE SPARES HAVE BEEN SOLD, SEND THIS SERVICE BULLETIN TO THE NEW OWNER. 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. 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.

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.
