Airworthiness Directives; the Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
The Boeing Company Model 737-600, -700, -700C, -800, and -900 series 
airplanes. This AD was prompted by reports of arcing and smoke at the 
left number 2 window in the flight deck. This AD requires inspecting 
the orientation of both sides of the coil cord connector keyways of the 
number 2 windows on the flight deck; re-clocking the connector keyways, 
if necessary; and replacing the coil cord assemblies on both number 2 
windows on the flight deck. We are issuing this AD to prevent arcing, 
smoke, and fire in the flight deck, which could lead to injuries to or 
incapacitation of the flightcrew.

DATES: This AD is effective February 10, 2014.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of February 10, 
2014.

SUPPLEMENTARY INFORMATION:

[[Page 546]]

Discussion

    We issued a supplemental notice of proposed rulemaking (SNPRM) to 
amend 14 CFR part 39 by adding an AD that would apply to the specified 
products. The SNPRM published in the Federal Register on July 17, 2012 
(77 FR 41931). We preceded the SNPRM with a notice of proposed 
rulemaking (NPRM), which published in the Federal Register January 26, 
2011 (76 FR 4567). The NPRM (76 FR 4567, January 26, 2011) proposed to 
require inspecting the orientation of both sides of the coil cord 
connector keyways of the number 2 windows on the flight deck; re-
clocking the connector keyways to 12 o'clock, if necessary; and 
replacing the coil cord assemblies on both number 2 windows on the 
flight deck. The SNPRM proposed to require changing the keyway position 
of certain receptacle connectors and adding airplanes to the 
applicability.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the proposal 
(77 FR 41931, July 17, 2012) and the FAA's response to each comment.

Request To Expand Applicability

    Boeing requested that we revise the applicability of the SNPRM (77 
FR 41931, July 17, 2012) to include the airplanes specified in Boeing 
Special Attention Service Bulletin 737-30-1058, Revision 5, dated April 
24, 2013. Boeing stated that the effectivity of this service bulletin 
includes 75 airplanes that were delivered with the identified unsafe 
condition.
    We agree that the 75 airplanes were delivered with the identified 
unsafe condition. However, we disagree with expanding the applicability 
of this final rule, because that would necessitate (under the 
provisions of the Administrative Procedure Act) reissuing the notice, 
reopening the period for public comment, considering additional 
comments subsequently received, and eventually issuing a final rule. We 
have determined that further delay of this final rule is not 
appropriate in light of the identified unsafe condition that exists in 
the airplanes specified in the applicability of the SNPRM (77 FR 41931, 
July 17, 2012). However, we might consider additional rulemaking in the 
future. We have not changed this final rule in this regard.

Request To Allow a Power Removal Procedure

    American Airlines (AAL) stated that it has no objections to the 
SNPRM (77 FR 41931, July 17, 2012), but requested that we allow the 
removal of power by opening circuit breakers in Step B.1., of Part 1, 
of the Work Instructions in Boeing Special Attention Service Bulletin 
737-30-1058, Revision 4, dated November 3, 2011. AAL stated that 
removal of power by opening circuit breakers is allowed in Step 
B.1.(b)., of Part 2, of the Work Instructions in Boeing Special 
Attention Service Bulletin 737-30-1058, Revision 4, dated November 3, 
2011. AAL explained that removal of power by opening circuit breakers 
would greatly reduce the disruption to airplane maintenance being 
accomplished concurrently.
    We agree with AAL's request. The requested procedure is included in 
Boeing Special Attention Service Bulletin 737-30-1058, Revision 5, 
dated April 24, 2013. We have changed paragraphs (g), (h), and (k) of 
this final rule (paragraph (k) in this final rule was identified as 
paragraph (i) in the SNPRM (77 FR 41931, July 17, 2012)) to refer to 
Boeing Special Attention Service Bulletin 737-30-1058, Revision 5, 
dated April 24, 2013, as the appropriate source of service information.
    Boeing Special Attention Service Bulletin 737-30-1058, Revision 5, 
dated April 24, 2013, specifies an additional inspection that is not 
included in Revision 4 of Boeing Special Attention Service Bulletin, 
dated November 3, 2011. For Group 1, Configuration 3, and Group 2, 
Configuration 2, airplanes, Boeing Special Attention Service Bulletin 
737-30-1058, Revision 5, dated April 24, 2013, specifies a general 
visual inspection for rubbing damage on the coil cords, and replacement 
of the coil cord with a new coil cord if rubbing damage is found. 
Boeing Special Attention Service Bulletin 737-30-1058, Revision 5, 
dated April 24, 2013, describes the labor hours required for the 
inspection as less than one hour for each coil cord. We have determined 
that this minor change in inspection procedures will not impose an 
additional burden on any operator; further, because it is a logical 
outgrowth of the notice, an additional opportunity for public comment 
will not be necessary. We have added the costs for this inspection to 
the Costs of Compliance section of this final rule, added new paragraph 
(i) to this final rule to require the coil cord inspection, and re-
designated subsequent paragraphs accordingly.
    Revision 5 of Boeing Special Attention Service Bulletin 737-30-
1058, dated April 24, 2013, also describes changes to a wire diagram 
reference and adds improved figure work instructions.

Request To Allow Re-installation of Coil Cords

    AAL requested that we allow retention and re-installation of coil 
cords if they are the new part number and no damage is found on them 
during the inspections proposed in the SNPRM (77 FR 41931, July 17, 
2012). AAL stated that since the new coil cord has been available for 
several years, it is possible that some airplanes may already have the 
new coil cord installed.
    We disagree with revising this final rule because this final rule 
and the referenced service information, Boeing Special Attention 
Service Bulletin 737-30-1058, Revision 5, dated April 24, 2013, specify 
further actions beyond simply installing a new coil cord. Figures 12 
and 14 in Boeing Special Attention Service Bulletin 737-30-1058, 
Revision 5, dated April 24, 2013, provide procedures for installation 
of receptacle connectors on the cover as part of the coil cord 
replacement for certain airplanes. Operators must ensure that all 
applicable actions specified in the service information have been done 
in addition to the installation of the new coil cord. However, under 
the provisions of paragraph (l) of this final rule, we will consider 
requests for approval of an alternative method of compliance (AMOC) to 
allow retaining and reinstalling the coil cord on airplanes after the 
effective date of this final rule, providing sufficient data is 
submitted to address the identified unsafe condition. We have not 
changed this final rule in this regard.

Request To Clarify Certain Work Instructions

    AAL requested that we clarify the work instructions for 
reinstallation of connector receptacle D10572 for Group 1, 
Configuration 1, airplanes as identified in Boeing Special Attention 
Service Bulletin 737-30-1058, Revision 4, dated November 3, 2011. AAL 
stated that Figures 12 and 14 of this service bulletin have steps to 
reinstall the connector receptacle, but the work instructions and 
figures for Group 1, Configuration 1 airplanes do not include steps 
that remove the connector receptacle.
    We agree to clarify. The removal of the receptacle connector D10572 
was addressed in Boeing Special Attention Service Bulletin 737-30-1058, 
Revision 3, dated July 7, 2010. The instructions were inadvertently 
omitted in Boeing Special Attention Service Bulletin 737-30-1058, 
Revision 4, dated November 3, 2011. Boeing has added the requested

[[Page 547]]

clarification to Boeing Special Attention Service Bulletin 737-30-1058, 
Revision 5, dated April 24, 2013. As referenced previously, we have 
specified Boeing Special Attention Service Bulletin 737-30-1058, 
Revision 5, dated April 24, 2013, as the appropriate source of service 
information in this final rule.

Additional Change to This Final Rule

    We have added new paragraph (j) to this final rule to specify 
exceptions to Boeing Special Attention Service Bulletin 737-30-1058, 
Revision 5, dated April 24, 2013, and redesignated the subsequent 
paragraphs accordingly.

Conclusion

    We reviewed the available data, including the comments received, 
and determined that air safety and the public interest require adopting 
this AD with the changes described previously and minor editorial 
changes. We have determined that these changes:
     Are consistent with the intent that was proposed in the 
SNPRM (77 FR 41931, July 17, 2012) for correcting the unsafe condition; 
and
     Do not add any additional burden upon the public than was 
already proposed in the SNPRM (77 FR 41931, July 17, 2012).
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this AD.

Costs of Compliance

    We estimate that this AD affects 712 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

    We estimate the following costs to do any necessary replacements 
that would be required based on the results of the inspection. We have 
no way of determining the number of aircraft that might need these 
replacements:

                                               On-Condition Costs

                                      assembly.
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, some of the costs of this AD may be 
covered under warranty, thereby reducing the cost impact on affected 
individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all costs in our cost 
estimate.

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

    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.
