Commercial Airplanes DC10 Service Bulletin ALERT SummaryNumber: DC10-28A253Original 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.

2. Group 6, Configuration 1:

Changes lower auxiliary fuel boost/transfer pump terminal board and associated wiring located in the Main Landing Gear (MLG) right-side wheel-well.

3. Group 4, 8, Configuration 1:

Changes upper auxiliary fuel boost/transfer pump terminal board and associated wiring located in the MLG left and right-side wheel well.

4. Group 1-8, Configuration 1:

Changes fuel tank boost/transfer pump ground wire termination.

5. Group 7:

Removes the Aux tank pump relays and associated wiring.

NOTE: The FCD is intended for use with ONLY airplane Original Equipment Manufacturer (OEM) certified fuel pumps and fuel pump housings, including OEM pump/housing spare parts and parts repaired per OEM approved repair instructions.

EFFECTIVITY DC-10-10, DC-10-10F, DC-10-15, DC-10-30, DC-10-30F, DC-10-30F(KC-10A), DC-10-30F(KDC-10), DC-10-40, DC-10-40F, MD-10-10F, and MD-10-30F Airplanes. Refer to Paragraph 1.A.1., Airplanes, for the list of affected airplanes.

COMPLIANCE Federal Aviation Administration (FAA) Airworthiness Directives AD 2013-08-23, AD 2002-13-10 and AD 2011-11-05 are 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 2013-08-23.

INDUSTRY SUPPORT INFORMATION Boeing warranty remedies are not available for the configuration changes given in this service bulletin.
