Federal Register Abstract

We are 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.

Airworthiness Directives; The Boeing Company Model 767 Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are 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.

DATES: This AD is effective July 22, 2011.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of July 27, 2011.
The Director of the Federal Register approved the incorporation by
reference of certain other publications listed in this AD as of August

SUPPLEMENTARY INFORMATION:

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2001-14-19, amendment 39-12330 (66 FR 38350,
July 24, 2001). That AD applies to the specified products. The NPRM was
published in the Federal Register on October 7, 2010 (75 FR 61999).
That NPRM proposed to continue to require, for certain airplanes,
reworking the bonding jumper assemblies on the drain tube assemblies of
the slat track housing of the wings. That NPRM also proposed to
continue to require, for certain other airplanes, 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. That NPRM also
proposed to require replacing the drain tube assemblies, and, for
certain airplanes, installing an additional electrostatic bond path for
the number 5 and 8 inboard slat track drain tube assemblies. For
certain other airplanes, that NPRM also proposed to require reworking
the bonding jumper assembly. That NPRM also proposed to revise the
applicability to include additional airplanes.

Comments

We gave the public the opportunity to participate in developing
this AD. The following presents the comments received on the proposal
and the FAA's response to each comment.

Support for the NPRM

Boeing concurs with the contents of the NPRM.

Request To Clarify Service Information

Continental Airlines requested that we revise the NPRM to correct
discrepancies in Boeing Service Bulletin 767-57A0094, Revision 2, dated
December 17, 2009. (That service bulletin was cited in the NPRM as the
appropriate source of service information for the drain tube
replacement on Model 767-200, -300, and -300F series airplanes.) In
Figure 13 (Sheet 2 of 5) on page 104, and Figure 14 (Sheet 2 of 5) on
page 109, the view identified as ``C'' should be identified as ``A.''
These discrepancies were communicated to Boeing and confirmed as
discrepancies.
We agree and have revised paragraph (j) in this final rule to
specify these corrections.

Request To Clarify Requirements

American Airlines stated that the Relevant Service Information
section of the NPRM provides the current requirements (for AD 2001-14-
19) but does not provide in detail the new additional requirements for
the NPRM. That paragraph, according to the commenter, merely provides
information regarding the service bulletins, not the specific proposed
requirements. The commenter added that the Relevant Service Information
section does not explain whether the new actions are to be done in
accordance with the original or revised service information. The
commenter

[[Page 35337]]

requested that the final rule provide in detail the specific actions
that would be required to comply with the new AD.
We agree to provide clarification. The commenter is correct that
the Relevant Service Information section describes only the procedures
specified in the service information referenced in an AD. When we
supersede an existing AD, the Relevant Service Information section
highlights the differences in any new service information to provide
notice for the public to comment on the new material. New service
information includes new service bulletins as well as significant
changes in revisions to previously described service bulletins. The
proposed requirements are then provided in ``The FAA's Determination
and Requirements of the Proposed AD.'' We have not changed the final
rule regarding this issue.

Explanation of Change to NPRM

We have revised the Costs of Compliance section in this final rule
to provide updated figures for the estimated number of affected
airplanes. This change does not significantly affect the fleet cost.

Conclusion

We reviewed the relevant data, considered the comments received,
and determined that air safety and the public interest require adopting
the AD with the change described previously. We also determined that
this change will not increase the economic burden on any operator or
increase the scope of the AD.

Costs of Compliance

There are about 920 airplanes of the affected design in the
worldwide fleet. The following table provides the estimated costs for
U.S. operators to comply with this proposed AD. The average labor rate
is $85 per hour.

Authority for This Rulemaking

Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I, section 106, describes the
authority of the FAA Administrator. Subtitle VII, Aviation Programs,
describes in more detail the scope of the Agency's authority.
We are issuing this rulemaking under the authority described in
subtitle VII, part A, subpart III, section 44701, ``General
requirements.'' Under that section, Congress charges the FAA with
promoting safe flight of civil aircraft in air commerce by prescribing
regulations for practices, methods, and procedures the Administrator
finds necessary for safety in air commerce. This regulation is within
the scope of that authority because it addresses an unsafe condition
that is likely to exist or develop on products identified in this
rulemaking action.

Regulatory Findings

We have determined that this AD will not have federalism
implications under Executive Order 13132. This AD will not have a
substantial direct effect on the States, on the relationship between
the national government and the States, or on the distribution of power
and responsibilities among the various levels of government.
For the reasons discussed above, I certify that this AD:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866,
(2) Is not a ``significant rule'' under DOT Regulatory Policies and
Procedures (44 FR 11034, February 26, 1979),
(3) Will not affect intrastate aviation in Alaska, and
(4) Will not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
