AD NUMBER: 2006-08-04
SUBJECT: Airworthiness Directive 2006-08-04
FAA is adopting a new airworthiness directive (AD) for certain
Boeing Model 767 airplanes.
This AD requires performing a test of the bonding resistance
between the engine fuel feed tube fitting and the front spar,
applying sealant on a hex nut inside the dry bay, and performing
any applicable corrective actions. This AD results from a report
that the engine fuel feed tubes were found not electrically bonded
to the front spar.
We are issuing this AD to prevent an ignition source from
entering the fuel tank during a lightning strike event, which could
cause a fuel tank explosion.
