Commercial Airplanes DC10 Service Bulletin SummaryNumber: DC10-28-256Original Issue: June 24, 2014 ATA System: 2800 SUBJECT: FUEL - Fuel Systems - Change Fuel Pump Control and Indication System Wiring

CONCURRENT REQUIREMENTS Refer to Paragraph 1.B., Concurrent Requirements.

BACKGROUND Frictional heating or sparking resulting from fuel pump failure, wear of fuel pump rotating components, or ingestion of debris by the fuel pump, may result in development of a fuel tank ignition source. Frictional heating or sparking in fuel pump inlets or priming system outlets exposed (i.e. not covered by fuel) to the tank ullage in combination with the ullage being flammable, may result in a fuel tank ignition event. Center wing auxiliary, fuselage auxiliary, and wing tip compartment (KC-10 only) fuel tanks may be subject to this condition since they are normally pumped dry over the course of a mission. A fuel tank ignition event could develop with a fuel pump running in an empty tank if the normal shutoff command is delayed or as a result of control system failures that keep the fuel pump in a latent uncommanded running condition. To ensure a timely fuel pump shutoff command revise flight crew shutoff procedures for center wing auxiliary, fuselage auxiliary, and wing tip compartment (KC-10 only) fuel tanks. To address the latent fuel pump uncommanded running condition change center wing auxiliary, fuselage auxiliary, and wing tip compartment (KC-10 only) fuel pump control and indication system wiring to detect and indicate fuel pump uncommanded running conditions. If not corrected, a fuel tank pump running in an empty fuel tank may result in a fuel tank ignition event.

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.
