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 737-100, -200, -200C, -300, -400, and -500
series airplanes. This AD was prompted by reports of chaffing, arcing,
and burning damage to the control cabin overhead wiring and ducting
with smoke and fire caused by metal clamps installed on certain hoses.
This AD requires inspecting for the presence of metal clamps, replacing
metal clamps installed on the hoses to the air conditioning temperature
sensor, gasper air outlet, and diffuser on the left side of the control
cabin with plastic tie straps, and inspecting for and repairing damaged
wire bundles. We are issuing this AD to prevent damage to wire bundles,
which could cause electrical arcing that could result in a fire or
smoke in the control cabin of the airplane.
DATES: This AD is effective April 1, 2014.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of April 1,
2014.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would apply to certain The Boeing Company
Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. The
NPRM published in the Federal Register on September 26, 2013 (78 FR
59304). The NPRM was prompted by reports of chaffing, arcing, and
burning damage to the control cabin overhead wiring and ducting with
smoke and fire caused by metal clamps installed on certain hoses. The
NPRM proposed to require inspecting for the presence of metal clamps,
replacing metal clamps installed on the hoses to the air conditioning
temperature sensor, gasper air outlet, and diffuser on the left side of
the control cabin with plastic tie straps, and inspecting for and
repairing damaged wire bundles. We are issuing this AD to correct
incorrectly installed metal clamps, which could cause wire bundle
damage and electrical arcing that could result in a fire or smoke in
the control cabin of the airplane.
Comments
We gave the public the opportunity to participate in developing
this AD. The following presents the comment received on the proposal
(78 FR 59304, September 26, 2013) and the FAA's response to that
comment.
Statement of Supplemental Type Certificate (STC) Effect on
Applicability
Aviation Partners Boeing stated that the installation of winglets
per STC ST01219SE (http://rgl.faa.gov/Regulatory_and_Guidance_Library/rgstc.nsf/0/BE866B732F6CF31086257B9700692796?OpenDocument&Highlight=st01219se) does
not affect the accomplishment of the proposed requirements.
We have re-designated paragraph (c) of the NPRM (78 FR 59304,
September 26, 2013) as paragraph (c)(1) in this final rule and added
new paragraph (c)(2) to this final rule to state that installation of
STC ST01219SE (http://rgl.faa.gov/Regulatory_and_Guidance_Library/rgstc.nsf/0/BE866B732F6CF31086257B9700692796?OpenDocument&Highlight=st01219se) does
not affect the ability to accomplish the actions required by this AD.
Therefore, for airplanes on which STC ST01219SE is installed, a
``change in product'' alternative method of compliance (AMOC) approval
request is not necessary to comply with the requirements of 14 CFR
39.17.
Conclusion
We reviewed the relevant data, considered the comment received, and
determined that air safety and the public interest require adopting
this AD with the change described previously and minor editorial
changes. We have determined that these minor changes:
[Agr]re consistent with the intent that was proposed in
the NPRM (78 FR 59304, September 26, 2013) for correcting the unsafe
condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM (78 FR 59304, September 26, 2013).
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 426 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:
Estimated costs
----------------------------------------------------------------------------------------------------------------
Cost on U.S.
Action Labor cost Parts cost Cost per product operators
----------------------------------------------------------------------------------------------------------------
Inspection and Replacement........ 2 work-hours x $85 $0 $170 per replacement. $72,420
per hour = $170 per
replacement.
----------------------------------------------------------------------------------------------------------------
We have received no definitive data that would enable us to provide
cost estimates for the on-condition actions specified in this AD. We
have no way of determining the number of products that may need these
actions.
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,
[[Page 10352]]
(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.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
