AD NUMBER: 2008-10-11
SUBJECT: Airworthiness Directive 2008-10-11 SUMMARY: The FAA is
adopting a new airworthiness directive (AD) for all Boeing Model
This AD requires revising the Airworthiness Limitations (AWLs)
section of the Instructions for Continued Airworthiness by
incorporating new limitations for fuel tank systems to satisfy
Special Federal Aviation Regulation No. 88 requirements.
This AD also requires 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.
