McDonnell DouglasCommercial Airplanes MD90 Service Bulletin SummaryNumber: MD90-28-010Original Issue: February 22, 2008 Revision 1: June 16, 2009 ATA System: 2800 SUBJECT: FUEL - Fuel Systems - Change or Replace Fuel Boost Pumps
CONCURRENT REQUIREMENTS Refer to Paragraph 1.B., Concurrent Requirements.
BACKGROUND The Special Federal Aviation Regulation (SFAR 88) safety review has determined the need to protect the fuel boost pump stator lead wires from being able to contact the pump rotor/shaft assembly. Lead wire contact and the resulting chafing may result in an ignition source (energized rotor assembly) being produced in the fuel boost pump inlet that could propagate into the fuel tank when the fuel boost pump inlet is not fully covered by fuel.
Replacement of the fuel boost pump will minimize the risk of a potential arc/spark condition that may occur within the airplane's fuel tanks at critical fuel boost pumps in the center wing and forward auxiliary tanks. If not corrected, there is a potential that an arc/spark condition could occur within the fuel boost pumps and propagate into the fuel tank.
This service bulletin is the result of the safety assessments conducted by Boeing under SFAR 88, "Fuel Tank System Fault Tolerance Evaluation Requirements".
ACTION Refer to Paragraph 1.D., Description.
EFFECTIVITY MD-90-30 Airplanes. Refer to Paragraph 1.A.1., Airplanes for the list of affected airplanes.
COMPLIANCE Federal Aviation Administration (FAA) Notice of Proposed Rule Making 2008-NM-113-AD, is related to this service bulletin.
