AD NUMBER: 2004-24-07
MANUFACTURER: Boeing SUBJECT: Airworthiness Directive 2004-24-07 SUMMARY: The FAA is adopting a new airworthiness
directive (AD) for certain Boeing Model 737-600, -700, -700C, -800,
and -900 series airplanes. This AD requires replacing the bracket
for the wire bundle of the fuel quantity indicating system (FQIS),
performing a general visual inspection of the FQIS wire bundle for
damage, and doing corrective actions if necessary. This AD is
prompted by are port of an incorrectly installed FQIS wire bundle.
We are issuing this AD to prevent chafing of the FQIS wire(s) in
the center fuel tank, which, when combined with a lightning strike
or a power wire short to the FQIS wire(s), could result in arcing
in the center fuel tank and consequent fuel tank explosion.
