Commercial Airplanes MD11 Service Bulletin ALERT SummaryNumber: MD11-28A133Original 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 MD-11 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) MD-11 FTD 28-03006, MD-11 FTD 28-12001, MD-11 FTD 28-13001 and MD-11 FTD 28-13004 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. Changes lower auxiliary fuel boost/transfer pump terminal board installation and associated wiring located in the Main Landing Gear (MLG) right-side wheel-well.

3. Changes fuel tank boost/transfer pump wire termination.
4. Group 4:
Removes the Forward Aux tank 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 MD-11 and MD-11F 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.
MANPOWER Refer to Paragraph 1.G., Manpower.
MATERIAL INFORMATION Boeing Supplied Kits/Parts.
Refer to Paragraph 2.A., Material - Price and Availability.
Operators are encouraged to complete the survey provided in APPENDIX A of this service bulletin to help Boeing predict the quantity and timing of the Boeing Supplied Kits/Parts.
