AD NUMBER: 2011-12-11
MANUFACTURER: The Boeing Company Model 767
Airplanes
SUBJECT: Airworthiness Directive 2011-12-11
SUMMARY: The FAA is superseding an existing
airworthiness directive (AD) for the products listed above.
That AD currently requires, for certain airplanes, reworking the
bonding jumper assemblies on the drain tube assemblies of the slat
track housing of the wings. For certain other airplanes, the
existing AD requires repetitive inspections of the drain tube
assemblies of the slat track housing of the wings to find
discrepancies, corrective actions if necessary, and terminating
action for the repetitive inspections.
This new AD also requires replacing the drain tube assemblies.
For certain airplanes, this new AD also requires installing an
additional electrostatic bond path for the number 5 and 8 inboard
slat track drain tube assemblies. For certain other airplanes, this
new AD also requires reworking the bonding jumper assembly. This
new AD also revises the applicability to include additional
airplanes.
This AD was prompted by (1) reports of fuel leaks from certain
drain locations of the slat track housing near the engine exhaust
nozzle, which could result in a fire when the airplane is
stationary, or taxiing at low speed; (2) reports of a bonding
jumper assembly of certain drain tubes that did not meet bonding
specifications and could result in electrostatic discharge and an
in-tank ignition source; and (3) reports of fuel leaks onto the
main landing gear (MLG) as a result of a cracked drain tube at the
number 5 or 8 slat track housing, which could let fuel drain from
the main fuel tanks into the dry bay area of the wings and onto hot
MLG brakes and result in a fire.
