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) SparesAffected: None.
B. Reason: An analysis by DAC has revealeda potential nuisance conditionof the "MASTERCAUTION" and "CENTER FUEL PRESS LO" indication lights illuminatingduring final approach and landing. This condition is possible on aircraft incorporating low fuelpressure indicationsystem with alternate fuel burn systemor aircraft incorporatingonly the low fuel pressure indication system. This condition couldoccur during failure of a center fuel tank boostpump or a nearly empty center fuel tank during final approach. Incorporationof the low fuelpressure indicationinhibit, which activates when flaps are approximately 6 degrees or greater, will minimize thepossibility of a potential nuisance condition of "MASTERCAUTION" and "CENTER FUELPRESS LO" indication lights illuminatingduring final approach and landing. C. Description: All Groups Thismodification installs low fuel pressure indication inhibit system as follows: (1) Installsa relay and receptacle in the electricalpower center (EPC) at stationY-160.000. (2) Installs low fuel pressure inhibit nameplate on forward overhead switch panel. (3) Revises existing electricalwiring. (4) Installs new electrical wiring.
