AD NUMBER: 2008-11-01
SUBJECT: Airworthiness Directive 2008-11-01 SUMMARY: We are adopting a
new airworthiness directive (AD) for certain Boeing Model 767-200,
-300,-300F, and -400ER series airplanes.
This AD requires revising the FAA-approved maintenance program
to incorporate new airworthiness limitations (AWLs) for fuel tank
systems to satisfy Special Federal Aviation Regulation No. 88
This AD would also require the initial inspection of certain
repetitive AWL inspections to phase in those inspections, and
repair if necessary. This AD results from a design review of the
fuel tank systems.
We are issuing this AD to prevent the potential for ignition
sources inside fuel tanks caused by latent failures,
alterations,repairs, or maintenance actions, which, in combination
with flammable fuel vapors, could result in a fuel tank explosion
and consequent loss of the airplane.
