# DC10 Service Bulletin **ALERT Summary**  **Number: DC10-28A253** Original Issue: June 05, 2014 ATA System: 2822 **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. Boeing Fleet Team Digest (FTD) DC-10, MD-10 FTD 28-03003, DC-10, MD-10 FTD 28-12001, DC-10, MD-10 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.

1.**Group 1-5, 8:** DC-10 Airplanes This service bulletin was examined by the Federal Aviation Administration (FAA). The changes specified in this service bulletin comply with the applicable regulations and are FAA approved, as well as European Aviation Safety Agency (EASA)/Joint Aviation Authorities (JAA) approved for all EASA/JAA approved airplanes listed in the service bulletin effectivity. This service bulletin and its approval were based on the airplane in its original Boeing delivery configuration or as modified by other approved Boeing changes. In addition, the Manager of the FAA Los Angeles Aircraft Certification Office approves the modification defined in this service bulletin as a Alternative Method of Compliance (AMOC) to the requirements of paragraph (g), (g)(1) and (h) of AD 2013-08-23 and to the repetitive inspection interval requirement of paragraph (a) of AD 2002-13-10 and paragraph (j) of AD 2011-11-05 as follows. Accomplishment of this service bulletin will allow the existing repetitive 18 month inspection interval to be increased to no later than 24 months and no later than every 24 months thereafter. All provisions of AD 2013-08-23, AD 2002-13-10 and AD 2011-11-05 that are not specifically referenced in the above statement remain fully applicable and must be complied with. If an airplane has a non-Boeing modification or repair that affects a component or system also affected by this service bulletin, the operator is responsible for obtaining appropriate regulatory agency approval before incorporating this service bulletin.

BLANK PAGE**3. ACCOMPLISHMENT INSTRUCTIONS A. GENERAL INFORMATION**  **WARNING:**IF ELECTRICAL POWER IS APPLIED TO THE AIRPLANE, MAKE SURE YOU OBEY 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. • Torque limits to tighten nuts and bolts are in DC-10, MD-10 SRM 51. 7. Refer to these SWPM chapters for applicable operations, as accepted procedures:

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.
