# DC10 Service Bulletin **ALERT Summary**  **Number: DC10-28A261** Original Issue: December 01, 2009 ATA System: 2822 **SUBJECT:**FUEL - Engine Fuel Supply - Fuel Pump Housing Electrical Connector Assembly and Fuel Boost/Transfer Pump - Inspection/Replacement 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 and DC-10 operators have reported instances of fuel pump housing electrical connector assembly, part number 60-84355-1, failures. Inspecting the fuel boost/transfer pump housing electrical connector assembly, fuel boost/transfer pump and replacing any non-serviceable part with a serviceable part as required based on inspection results, will minimize the possibility of a potential ignition source in the fuel tanks and potential fuel tank explosion. If not corrected, insulation resistance degradation and/or arcing in the potted backside of the fuel boost/transfer pump housing electrical connector assembly could compromise the performance of the fuel boost/transfer pump housing electrical connector assembly and result in a failure that can introduce an ignition source into the fuel tank and potential fuel tank explosion. **ACTION** This service bulletin provides instructions to inspect/replace each fuel pump housing electrical connector assembly and fuel boost/transfer pump. **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** Refer to Paragraph 1.E., Compliance.

In addition, the Manager of the FAA Los Angeles Aircraft Certification Office approves the action (i.e. inspection or modification) defined in this service bulletin as an alternative method of compliance to the requirements of Paragraph (k) of FAA AD 2007-15-05. All provisions of FAA AD 2007-15-05 that are not specifically referenced in the above statement remain fully applicable and must be complied with. **G. Manpower** The table below shows an estimate of the task hours necessary to do this inspection for each airplane. This estimate is for direct labor only, done by an experienced crew. Adjust the estimate with operator task hour data if necessary. The estimate does not include lost time. These are some examples of lost time: • Time to adjust to the workplace • Time to schedule the work • Time to inspect the work • Time to cure the materials • Time to make the parts • Time to find the tools. **Group 1: Elapsed Hours**  **Task Hours Number of Persons**  **Task** 4.0 8.0 2 Open Access 12.0 24.0 2 Inspect *0.05 - 12.00 *0.1 - 24.0 2 Change 4.0 8.0 2 Close Access
