Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede Airworthiness Directive (AD) 2013-26-
08, which applies to certain The Boeing Company Model 737-600, -700, -
700C, -800, -900, and -900ER series airplanes. AD 2013-26-08 currently 
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. Since we 
issued AD 2013-26-08, we have determined that additional airplanes are 
subject to the identified unsafe condition. This proposed AD would add 
airplanes to the applicability. We are proposing this AD

[[Page 3528]]

to prevent arcing, smoke, and fire in the flight deck, which could lead 
to injuries to or incapacitation of the flightcrew.

Discussion

    On December 20, 2013, we issued AD 2013-26-08, Amendment 39-17717 
(79 FR 545, January 6, 2014), for certain The Boeing Company Model 737-
600, -700, -700C, -800, -900, and -900ER series airplanes. AD 2013-26-
08 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. AD 2013-
26-08 resulted from reports of arcing and smoke at the left number 2 
window in the flight deck. We issued AD 2013-26-08 to prevent arcing, 
smoke, and fire in the flight deck, which could lead to injuries to or 
incapacitation of the flightcrew.

Actions Since AD 2013-26-08, Amendment 39-17717 (79 FR 545, January 6, 
2014) Was Issued

    In AD 2013-26-08, Amendment 39-17717 (79 FR 545, January 6, 2014), 
a commenter to the SNPRM (77 FR 41931, July 17, 2012) requested that we 
add additional airplanes to the applicability. We determined that 
further delay of AD 2013-26-08 was not appropriate in light of the 
identified unsafe condition that existed on the airplanes specified in 
the applicability of AD 2013-26-08. We stated that we might consider 
additional rulemaking in the future. We now have determined that 
further rulemaking is indeed necessary, and this proposed AD follows 
from that determination.

FAA's Determination

    We are proposing this AD because we evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of the same type design.

Proposed AD Requirements

    This proposed AD would retain all requirements of AD 2013-26-08, 
Amendment 39-17717 (79 FR 545, January 6, 2014). This proposed AD would 
add Group 3 airplanes, as identified in Boeing Special Attention 
Service Bulletin 737-30-1058, Revision 5, dated April 24, 2013, to the 
applicability.

Costs of Compliance

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

                                                                     Estimated Costs

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

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

                                      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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 the proposed 
regulation:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Is not a ``significant rule'' under the 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.
