SUBJECT: FUEL - Engine Fuel Supply - Replace Fuel Pump Control Relays with Fault Current
Detectors and Change Fuel Tank Boost/Transfer Pump Wire Termination
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
Refer to Paragraph 1.B., Concurrent Requirements.
BACKGROUND
DC-10 and MD-10 fuel boost/transfer pumps failures have occurred due to electrical ground or phase to phase
fault within the fuel pump electrical interface connector shell, pump motor windings and pump motor assembly
lead wires. These failures have caused arcing damage to the interface connector shell or fuel pump explosion
proof compartment. Investigation by Boeing has determined that during an electrical arcing event the affected
Remote Control Circuit Breaker (RCCB) may not react to the thermal rise from an electrical fault fast enough to
prevent arcing damage. Replacing the fuel boost/transfer pump control relays with Fault Current Detectors (FCD)
will minimize arcing events at the fuel pump electrical interface connector, pump motor windings and pump
motor assembly lead wires that could breach the explosion proof compartment. If not corrected, failure of the
connector or fuel pump motor could result in a breach of the fuel boost/transfer pump interface connector shell
or the fuel pump housing assembly and potentially become a fuel tank ignition source.
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.

FTD 28-13001 and DC-10, MD-10 FTD 28-13003 are related to this service bulletin.
ACTION
This service bulletin provides instructions to do as follows:
1. Replaces fuel boost/transfer pump control relays in the Center Accessory Compartment (CAC), Electrical
Power Center (EPC) and Avionics Compartment (AC) forward equipment panel with fuel boost/transfer
pump FCDs.

ALL PRECAUTIONS WHILE YOU DO WORK. IF YOU DO NOT OBEY THE
PRECAUTIONS, DEATH OR INJURY TO PERSONS, AND DAMAGE TO THE AIRPLANE
CAN OCCUR.
CAUTION: KEEP THE WORK AREA, WIRES AND ELECTRICAL BUNDLES CLEAN OF METAL
PARTICLES OR CONTAMINATION WHEN YOU USE TOOLS. UNWANTED MATERIAL,
METAL PARTICLES OR CONTAMINATION CAUGHT IN WIRE BUNDLES CAN CAUSE
DAMAGE TO THE BUNDLES. DAMAGED WIRE BUNDLES CAN CAUSE SPARKS OR
OTHER ELECTRICAL DAMAGE.
CAUTION: ELECTRICALLY GROUND THE AIRPLANE. THIS WILL HELP TO PREVENT DAMAGE
TO THE AIRPLANE OR EQUIPMENT.
NOTE: 1. Manual titles are referred to by acronyms. Refer to Paragraph 1.J., References, for
definition of the acronyms.
2. Equivalent parts are listed in the AEPL, Drawing 7595071.
3. Use the approved fastener and process material substitutions, in accordance DC-10,
MD-10 SRM 51.
4. If the length of any fastener specified in this service bulletin does not meet installation
standards given in Structural Repair Manual (SRM) Chapter 51, then a fastener of
the same specification, or an approved substitute, with a length which meets the
installation standards given in SRM Chapter 51 may be used. In addition, washers
may be installed for fastener grip length in accordance with SRM Chapter 51. Refer
to SOPM 20-50-01 for alternate full threaded fasteners (screws) needed for installation
in this service bulletin.
5. A 1/8-inch thick stack of the same type washers called for in this service bulletin is
the maximum thickness which may be used under fastener head or nut to counteract
accumulation of tolerances.
EXCEPTION: When the available fastener length increments are greater than
1/16-inch, a 3/16-inch thick stack of the same type washers may be used.
6. Unless shown differently, these dimensions and tolerances are used:
 Linear dimensions are in inches.
 Tolerance on linear dimensions, other than rivet and bolt edge margins, is plus
or minus 0.03 inch.
 Tolerance on rivet and bolt edge margin is plus or minus 0.05 inch.
 Angular tolerance is plus or minus 2 degrees.
 Hole dimensions for standard solid rivets are in DC-10, MD-10 SRM 51.

8. Obey all of the warnings and cautions given in the specified manual sections.
9. These work instructions refer to procedures included in other Boeing documents.
When the words "refer to" are used and the operator has an accepted alternative
procedure, the accepted alternative procedure can be used. When the words "in
accordance with" are included in the instruction, the procedure in the Boeing document
must be used.
10. Some Boeing parts are supplied in a temporary configuration. Those parts are
identified with a 'U' or 'Y' in place of the '-' (dash) in the part number. It is permitted
to install parts identified with a 'U' or 'Y' as an alternative to the '-' (dash) number
part. Boeing Drawing SE10000000, Sheets 5.0 and 6.0 contain more data.
11. If it is necessary to remove more parts for access, you can remove those parts. If
you can get access without removing identified parts, it is not necessary to remove
all of the identified parts. Jacking and shoring limitations must be observed.
12. Where the work instructions include installation of a kept part, a new or serviceable
part with the same part number can be installed as an alternative to the kept part.
13. This service bulletin includes functional test procedures for the systems changed by
this service bulletin. More functional tests can possibly be necessary in accordance
with standard maintenance practices because of interruption to other airplane systems.
14. Review and understand all general notes of Service Rework Drawing SR10280053
sheets 3, 3.1, 3.2 before start of modification.
