14 CFR Part 39

[Docket No. FAA-2015-0075; Directorate Identifier 2014-NM-202-AD; 
Amendment 39-18461; AD 2016-07-16]

Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are superseding Airworthiness Directive (AD) 2013-26-08 for 
certain The Boeing Company Model 737-600, -700, -700C, -800, -900, and 
-900ER series airplanes. AD 2013-26-08 required 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. This new AD adds airplanes to the 
applicability. AD 2013-26-08 resulted from reports of arcing and smoke 
at the left number 2 window in the flight deck. This AD was prompted by 
a determination that additional airplanes are subject to the same 
identified unsafe condition. 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 May 12, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of February 10, 
2014 (79 FR 545, January 6, 2014).

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2013-26-08, Amendment 39-17717 (79 FR 545, 
January 6, 2014) (``AD 2013-26-08''). AD 2013-26-08 applied to certain 
The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER 
series airplanes. The NPRM published in the Federal Register on January 
23, 2015 (80 FR 3527) (``the NPRM''). AD 2013-26-08 resulted from 
reports of arcing and smoke at the left number 2 window in the flight 
deck. The NPRM was prompted by a determination that additional 
airplanes are subject to the same identified unsafe condition. The NPRM 
proposed to continue 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, if necessary; and 
replacing the coil cord assemblies on both number 2 windows on the 
flight deck. The NPRM also proposed to add airplanes to the 
applicability. 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.

Comments

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

Support for the NPRM

    Boeing stated that it supports the NPRM as written.

Effect of Winglets on Accomplishment of the Proposed Actions

    Aviation Partners Boeing stated that the installation of winglets 
per Supplemental Type Certificate (STC) ST00830SE (http://rgl.faa.gov/
Regulatory_and_Guidance_Library/rgstc.nsf/0/
184de9a71ec3fa5586257eae00707da6/$FILE/ST00830SE.pdf) does not affect 
the accomplishment of the manufacturer's service instructions.
    We agree with the commenter that STC ST00830SE (http://rgl.faa.gov/
Regulatory_and_Guidance_Library/rgstc.nsf/0/
184de9a71ec3fa5586257eae00707da6/$FILE/ST00830SE.pdf) does not affect 
the accomplishment of the manufacturer's service instructions. 
Therefore, the installation of STC ST00830SE does not affect the 
ability to accomplish the actions required by this AD. We have not 
changed this AD in this regard.

Comment Regarding Applicability

    United Airlines (UAL) stated that it found it curious that the 
technical compliance mandated in AD 2013-26-08 was per Boeing Special 
Attention Service Bulletin 737-30-1058, Revision 5, dated April 24, 
2013, whereas the airplane applicability in AD 2013-26-08 was based on 
Boeing Special Attention Service Bulletin 737-30-1058, Revision 4, 
dated November 3,

[[Page 20220]]

2011. UAL stated that, consequently, it anticipated further regulatory 
action that would include the Group 3 airplanes specified in Boeing 
Special Attention Service Bulletin 737-30-1058, Revision 5, dated April 
24, 2013, and has acted accordingly. UAL also stated that, since it was 
already planning accomplishment on the Group 3 airplanes, the only 
impact to it will be to change the AD number on the compliance 
documentation. UAL stated that it has no further comments at this time.
    We acknowledge UAL's comment. No change to this AD is necessary.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
this AD as proposed except for minor editorial changes. We have 
determined that these minor changes:
    <bullet> Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
    <bullet> Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Costs of Compliance

    We estimate that this AD affects 718 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

                                                                     Estimated Costs

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

    We estimate the following costs to do any necessary replacements 
that would be required based on the results of the coil cord 
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

    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.
