SummaryNumber: MD80-28-228Original Issue: September 27, 2013
ATA System: 2800
SUBJECT: FUEL - Fuel Systems - Install Ground Fault Interrupter Relays and Change Fuel Pump
System Wiring
CONCURRENT REQUIREMENTS
Refer to Paragraph 1.B., Concurrent Requirements.
BACKGROUND
Frictional heating or sparking may develop from fuel pump failure, wear of fuel pump rotating components, or
ingestion of debris by the pump. Electrical faults in a fuel pump may result in electrical arc burn through of a fuel
pump. Frictional heating or sparking and electrical arc burn through in fuel pump inlets or priming system outlets
exposed (i.e. not covered by fuel) to the tank ullage in combination with the ullage being flammable, may result
in a fuel tank ignition event. A fuel tank ignition event could develop with a pump running in an empty tank if the
normal shutoff command is delayed or as a result of control system failures that keep the pump in a latent
uncommanded running condition. Center wing and auxiliary fuel tanks may be subject to this condition since
they are normally pumped dry over the course of a flight. If not corrected frictional heating or sparking, electrical
arc burn through, or a fuel tank pump running in an empty fuel tank may result in a fuel tank ignition event.
This service bulletin is the result of the safety assessments conducted by Boeing under a Special Federal Aviation
Regulation (SFAR) 88, Fuel Tank System Fault Tolerance Evaluation Requirements.
Boeing Fleet Team Digest (FTD) MD-80 FTD 28-03001 is related to this service bulletin.
ACTION
This service bulletin installs Ground Fault Interrupter (GFI) relays and cuts/coils/stows wires to center wing and
auxiliary fuel tank pump motor neutral circuits.
EFFECTIVITY
All DC-9-81 (MD-81), DC-9-82 (MD-82), DC-9-83 (MD-83), DC-9-87 (MD-87) and MD-88 Airplanes. Refer to
Paragraph 1.A.1., Airplanes, for the list of affected airplanes.
COMPLIANCE
Federal Aviation Administration (FAA) Airworthiness Directive AD 2012-18-05 is related to this service bulletin.
Boeing recommends that the change given in this service bulletin be done within 60 months after the effective
date of AD 2012-18-05.

2. Spares Affected
None.
B. Concurrent Requirements
The service bulletins listed below must be done before or at the same time as this service bulletin:
NOTE: For each service bulletin listed below the concurrent requirements are applicable only to the
airplanes listed in the effectivity of that service bulletin.

Revision 1 or Revision 2
The Boeing Company
C. Reason
Frictional heating or sparking may develop from fuel pump failure, wear of fuel pump rotating
components, or ingestion of debris by the pump. Electrical faults in a fuel pump may result in electrical
arc burn through of a fuel pump. Frictional heating or sparking and electrical arc burn through in fuel
pump inlets or priming system outlets exposed (i.e. not covered by fuel) to the tank ullage in combination
with the ullage being flammable, may result in a fuel tank ignition event. A fuel tank ignition event could
develop with a pump running in an empty tank if the normal shutoff command is delayed or as a result
of control system failures that keep the pump in a latent uncommanded running condition. Center wing
and auxiliary fuel tanks may be subject to this condition since they are normally pumped dry over the
course of a flight. If not corrected frictional heating or sparking, electrical arc burn through, or a fuel
tank pump running in an empty fuel tank may result in a fuel tank ignition event.
This service bulletin is the result of the safety assessments conducted by Boeing under a Special
Federal Aviation Regulation (SFAR) 88, Fuel Tank System Fault Tolerance Evaluation Requirements.
