SERVICE BULLETIN SUMMARY

NOTE: This summary is for information only and reflects the Intent of the attached

FAA approved Service Bulletin.

SUBJECT: FUEL - Indicating - Install

Low Fuel Pressure Indication

Inhibit System.

NOTE

MD-80 Service Bulletin 28-53, which

installs low fuel pressure indication

system, must be accomplished prior to

or in conjunction with Service Bulletin

28-63. Only aircraft listed in the

effectivity of Service Bulletin 28-53

that are contained in Service Bulletin

28-63 are affected by this contingency.

ANALYSIS: An analysis by DAC has

revealed a potential nuisance condition

of the "MASTER CAUTION" and "CENTER

FUEL PRESS LO" indication lights

illuminating during final approach

and landing. This condition is

possible on aircraft incorporating low

fuel pressure indication system with

alternate fuel burn system or aircraft

incorporating only the low fuel

pressure indication system. This

condition could occur during failure

of a center fuel tank boost pump or a

nearly empty center fuel tank during

final approach.

wiring. (4) Installs new electrical

wiring. Incorporation of the low fuel

pressure indication inhibit, which

activates when flaps are approximately

6 degrees or greater, will minimize the

possibility of a potential nuisance

condition of "MASTER CAUTION" and

"CENTER FUEL PRESS LO" indication

lights illuminating during final

approach and landing.

EFFECTIVITY: DC-9-81, -82, -83, and

-87 (MD-81, -82, -83, and -87); MD-88

aircraft. (See Service Bulletin 28-63

for detailed Effectivity.)

DESCRIPTION: All Groups - Installs low

fuel pressure indication inhibit system as follows: (1) Installs a relay and

receptacle in the electrical power

center (EPC) at station Y-160.000.

(2) Installs low fuel pressure inhibit

nameplate on forward overhead switch

panel. (3) Revises existing electrical

This modification will be incorporated prior to delivery on

all applicable DC-9-81, -82, -83, -87, and MD-88 aircraft,

manufacturer's fuselage numbers 1872, 1886, 1899, 1922, and

subsequent.

(2) Spares Affected:

None.

B. Reason:

An analysis by DAC has revealed a potential nuisance condition of

the "MASTER CAUTION" and "CENTER FUEL PRESS LO" indication lights

illuminating during final approach and landing. This condition is

possible on aircraft incorporating low fuel pressure indication system

with alternate fuel burn system or aircraft incorporating only the low

fuel pressure indication system. This condition could occur during

failure of a center fuel tank boost pump or a nearly empty center fuel

tank during final approach. Incorporation of the low fuel pressure

indication inhibit, which activates when flaps are approximately

6 degrees or greater, will minimize the possibility of a potential

nuisance condition of "MASTER CAUTION" and "CENTER FUEL PRESS LO"

indication lights illuminating during final approach and landing.

C. Description:

All Groups

This modification installs low fuel pressure indication inhibit system

as follows:

(1) Installs a relay and receptacle in the electrical power

center (EPC) at station Y-160.000.

(2) Installs low fuel pressure inhibit nameplate on forward

overhead switch panel.

(3) Revises existing electrical wiring.

(4) Installs new electrical wiring.

D. Compliance:

It is recommended that this modification be accomplished at the earliest

practical maintenance period.

E. Approval:

The resultant modification described in paragraph 1.C has been shown

to comply with the applicable Federal Aviation Regulations and is FAA

approved for the affected aircraft listed in paragraph 1.A.

F. Manpower:

NOTE: Man-hours are estimated based on work to be performed

by skilled personnel on aircraft/unit which has been

placed in a maintenance status. The man-hour/elapsed

time estimates do not include:

1. Preparation for the modification: Examples; defueling,

purging, placing work stands, opening standard access

doors, obtaining tools, and jacking when not essential

to the modification.

2. Nonproductive elapsed time: Examples; sealant or

adhesive cure time, cleaning, paint drying time, lunch

and/or rest periods, and quality assurance inspections.

3. Administrative functions: Examples; planning,

engineering liaison, parts requisition, shift change

coordination, and report writing.

Operators should take the above into consideration when

scheduling this modification.

Man-hours required for wire routing for aircraft with forward

auxiliary fuel tank are to be determined by the operator.

This modification may be accomplished in the following approximate

man-hours or elapsed hours per aircraft:
