AD NUMBER: 2008-11-07
MANUFACTURER: Boeing
SUBJECT: Airworthiness Directive 2008-11-07 SUMMARY: We are adopting a
new airworthiness directive (AD) for all Boeing Model 757
airplanes. This AD requires installation of an automatic shutoff
system for the center tank fuel boost pumps, and installation of a
placard in the airplane flight deck if necessary. This AD also
requires revisions to the Limitations and Normal Procedures
sections of the airplane flight manual to advise the flight crew of
certain operating restrictions for airplanes equipped with an
automated center tank fuel pump shutoff control. This AD also
requires a revision to the Airworthiness Limitations(AWLs) section
of the Instructions for Continued Airworthiness to incorporate AWLs
No. 28-AWL-20 and No. 28-AWL-26. This AD also requires replacement
of the fuel control panel assembly with a modified part,
installation of two secondary pump control relays for the center
tank fuel pumps, other specified actions, and concurrent
modification of the fuel control panel assembly.This AD results
from fuel system reviews conducted by the manufacturer. We are
issuing this AD to prevent center tank fuel pump operation with
continuous low pressure, which could lead to friction sparks or
overheating in the fuel pump inlet that could create a potential
ignition source inside the center fuel tank; these conditions, in
combination with flammable fuel vapors, could result in a center
fuel tank explosion and consequent loss of the airplane.
