Revision 1: June 16, 2009

ATA System: 2822

SUBJECT: FUEL - Pump Fuel Boost - 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, forward and aft auxiliary fuel 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

All MD-80 and DC-9-31, DC-9-32, DC-9-32(VC9C), DC-9-32F, DC-9-32F(C-9A), DC-9-32F(C-9B), DC-9-33F,

DC-9-34, DC-9-34F, DC-9-41 and DC-9-51 Airplanes. Refer to Paragraph 1.A.1., Airplanes for affected airplanes.

COMPLIANCE

BOEING SERVICE BULLETIN DC9-28-212
B. Concurrent Requirements

Group 1-8, Configuration 1:

The service bulletin listed below must be done at the same time as this service bulletin:

Company Service Bulletin Description

Change or replace fuel boost pump 398000-1

to 398000-2 configuration.

Argo-Tech 398000-28-2 Revision 1

A copy may be obtained from:

Argo-Tech Corporation 23555 Euclid Avenue

Cleveland, Ohio 44117 USA

Phone: (216) 692-7151

Group 1-8, Configuration 2:

None.

C. Reason

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, forward and aft auxiliary fuel 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".

Revision 1 is sent to change the Revision level of Argo-Tech Service Bulletin 398000-28-2 to Revision

1.
