Federal Register Abstract
We are superseding an existing airworthiness directive (AD) for certain Model 757-200, -200PF, -200CB, and -300 series airplanes. That AD currently requires inspecting certain power feeder wire bundles for damage, inspecting the support clamps for these wire bundles to determine whether the clamps are properly installed, and performing corrective actions if necessary. This new AD requires additional inspections for certain airplanes. This AD was prompted by a report that a power feeder wire bundle chafed against the number six auxiliary slat track, causing electrical wires in the bundle to arc, which damaged both the auxiliary slat track and power feeder wires. We are issuing this AD to prevent arcing that could be a possible ignition source for leaked flammable fluids, which could result in a fire. Arcing could also result in a loss of power from the generator connected to the power feeder wire bundle, and consequent loss of systems, which could reduce controllability of the airplane.

SUMMARY: We are superseding an existing airworthiness directive (AD)
for certain Model 757-200, -200PF, -200CB, and -300 series airplanes.
That AD currently requires inspecting certain power feeder wire bundles
for damage, inspecting the support clamps for these wire bundles to
determine whether the clamps are properly installed, and performing
corrective actions if necessary. This new AD requires additional
inspections for certain airplanes. This AD was prompted by a report
that a power feeder wire bundle chafed against the number six auxiliary
slat track, causing electrical wires in the bundle to arc, which
damaged both the auxiliary slat track and power feeder wires. We are
issuing this AD to prevent arcing that could be a possible ignition
source for leaked flammable fluids, which could result in a fire.
Arcing could also result in a loss of power from the generator
connected to the power feeder wire bundle, and consequent loss of
systems, which could reduce controllability of the airplane.
DATES: This AD is effective April 4, 2012.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of April 4, 2012.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2007-03-01, amendment 39-14912 (72 FR 3939,
January 29, 2007). That AD applies to the specified products. The NPRM
was published in the Federal Register on January 18, 2011 (76 FR 2848).
That NPRM proposed to continue to require inspecting certain power
feeder wire bundles for damage, inspecting the support clamps for those
wire bundles to determine whether the clamps are properly installed,
and performing corrective actions if necessary. That NPRM also proposed
to require additional inspections for certain 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.
Requests To Correct Figure Reference in Paragraph (i) of the NPRM (76
FR 2848, January 18, 2011)
United Airlines and American Airlines requested that paragraph (i)
of the NPRM (76 FR 2848, January 18, 2011) be changed to reference
Figure 1 rather than Figure 3 of Boeing Special Attention Service
Bulletin 757-24-0105, Revision 5, dated July 30, 2009. Boeing Special
Attention Service Bulletin 757-24-0105, Revision 5, dated July 30,
2009, has a typographical error referencing the incorrect figure.
United Airlines also requested that the NPRM refer to Boeing
Information Notice 757-24-0105 IN 03, dated August 19, 2009. United
Airlines stated that Boeing Information Notice 757-24-0105 IN 03, dated
August 19, 2009, was issued to notify operators of this error.
We agree to revise paragraph (i) of this AD to refer to Figure 1 of
Boeing Special Attention Service Bulletin 757-24-0105, Revision 5,
dated July 30, 2009. We have confirmed that the correct figure is
Figure 1; therefore, we have revised paragraph (i) of this AD to refer
to Figure 1 of Boeing Special Attention Service Bulletin 757-24-0105,
Revision 5, dated July 30, 2009. We have not revised paragraph (i) of
this AD to refer to Boeing Information Notice 757-24-0105 IN 03, dated
August 19, 2009, because we revised that paragraph to refer to the
correct figure.
Request To Add Inspection To Determine Airplane Configuration
American Airlines requested that the NPRM (76 FR 2848, January 18,
2011) be revised to include an inspection to determine if the airplane
has one or two attach brackets on the left wing prior to accomplishing
the required rework. American Airlines stated that Group 2 airplanes
were moved to Group 1 in Boeing Special Attention Service Bulletin 757-
24-0105, Revision 5, dated July 30, 2009, because some airplanes have
two attach brackets on the left wing, similar to earlier Group 1
airplanes identified in previous revisions of that service bulletin.
American Airlines stated that the NPRM does not contain a step to
determine the airplane configuration before the rework.
We disagree with adding an inspection to determine the airplane
configuration; however, we agree to clarify paragraph (i) of this AD.
Therefore, we have revised paragraph (i) of this AD to specify the
affected airplanes on which the actions are required by that paragraph.
Request To Clarify Affected Airplanes in Paragraph (i) of the NPRM (76
FR 2848, January 18, 2011)
United Airlines requested that a statement be added to clarify that
the new requirement specified in paragraph (i) of the NPRM (76 FR 2848,
January 18, 2011) is only applicable to airplanes with upper and lower
brackets installed in the left wing (Group 1, Configuration 1
airplanes), as defined in Boeing Special Attention Service Bulletin
757-24-0105, Revision 5, dated July 30, 2009. United Airlines stated
that the NPRM is unclear regarding which
[[Page 12167]]
airplanes are affected by the new requirements.
We agree that clarification is needed. Airplanes in Group 1, as
specified in Boeing Special Attention Service Bulletin 757-24-0105,
Revision 5, dated July 30, 2009, could be in the configuration shown in
Figure 1 (Configuration 1 with two attach brackets on the left wing) or
Figure 3 (Configuration 2 with one attach bracket on the left wing).
Therefore, as stated previously, we have clarified paragraph (i) of
this AD to specify the affected airplanes.
Request To Provide Credit for Previous Work Done Using Boeing Special
Attention Service Bulletin 757-24-0105, Revision 5, Dated July 30, 2009
European Air Transport, a company of DHL, requested that we revise
the NPRM (76 FR 2848, January 18, 2011) to provide credit to operators
that have accomplished inspections and corrective actions prior to the
effective date of this AD in accordance with Boeing Special Attention
Service Bulletin 757-24-0105, Revision 5, dated July 30, 2009. European
Air Transport pointed out that the NPRM provides credit for actions
accomplished using previous revisions of Boeing Special Attention
Service Bulletin 757-24-0106, which is applicable to Model 757-300
airplanes.
We agree that inspections and corrective actions done before the
effective date of this AD in accordance with Boeing Special Attention
Service Bulletin 757-24-0105, Revision 5, dated July 30, 2009, are
acceptable for accomplishing the applicable actions specified in this
AD. However, operators may always accomplish the actions in an AD using
the required service information at any time before the effective date
of the AD, as allowed by the phrase ``unless the actions have already
been done.'' Therefore, because these actions are not required to be
repeated, it is unnecessary to provide specific credit for these
actions. We have made no change to the AD in this regard.
Additional Changes to Final Rule
We have revised the headings of Tables 1, 2, 3, 4, and 5 of this AD
to clarify the purpose of the content in those tables.
We have included headings for paragraphs (i) and (j) of this AD to
clarify the purpose of the content in those paragraphs.
Boeing Special Attention Service Bulletin 757-24-0105, Revision 3,
dated October 3, 2006; and Revision 4, dated January 4, 2008; have been
added to Table 5, ``Previous Service Information for Paragraph (g) of
this AD,'' of this AD.
We have also revised the headings for and wording in paragraphs (h)
and (k) of this AD; these changes have not changed the intent of these
paragraphs.
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 changes described previously and minor editorial
changes. We have determined that these minor changes:
<bullet> Are consistent with the intent that was proposed in the
NPRM (76 FR 2848, January 18, 2011) for correcting the unsafe
condition; and
<bullet> Do not add any additional burden upon the public than was
already proposed in the NPRM (76 FR 2848, January 18, 2011).
We also determined that these changes will not increase the
economic burden on any operator or increase the scope of the AD.
Costs of Compliance
We estimate that this AD affects 683 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:

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,
[[Page 12168]]
(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.

auxiliary slat track and power feeder wires. The Federal Aviation
Administration is issuing this AD to prevent arcing that could be a
possible ignition source for leaked flammable fluids, which could
result in a fire. Arcing could also result in a loss of power from
the generator connected to the power feeder wire bundle, and
consequent loss of systems, which could reduce controllability of
the airplane.
(f) Compliance
You are responsible for having the actions required by this AD
performed within the compliance times specified, unless the actions
