MANUFACTURER: The Boeing Company Model 767-200,
-300, -300F, and -400ER Series Airplanes SUBJECT: Airworthiness Directive 2008-11-01 R1
SUMMARY: The FAA is revising an existing airworthiness
directive (AD), which applies to certain Model 767-200, -300,
-300F, and -400ER series airplanes. That AD currently 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 requirements. That AD
also requires an initial inspection to phase in certain repetitive
AWL inspections, and repair if necessary. This AD clarifies the
intended effect of the AD on spare and on- airplane fuel tank
system components. 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.
DATES: This AD is effective January 12, 2010.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in the AD as of January
On June 25, 2008 (73 FR 29414, May 21, 2008), the Director of the
Federal Register approved the incorporation by reference of a
certain other publication listed in the AD.
