ACTION: Supplemental notice of proposed rulemaking (NPRM); reopening of comment period. AGENCY: mstockstill on DSK4VPTVN1PROD with PROPOSALS Examining the AD Docket We are revising an earlier proposed airworthiness directive (AD) for certain The Boeing Company Model 737–600, –700, –700C, –800, and –900 series airplanes. That NPRM 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. That NPRM was prompted by reports of arcing and smoke at the left number 2 window in the flight deck. This action revises that NPRM by changing the keyway position of certain receptacle connectors and adding airplanes to the applicability. We are proposing this supplemental SUMMARY: VerDate Mar<15>2010 17:09 Jul 16, 2012 Jkt 226001 NPRM (SNPRM) to prevent arcing, smoke, and fire in the flight deck, which could lead to injuries to or incapacitation of the flightcrew.

SUPPLEMENTARY INFORMATION: Comments Invited We invite you to send any written relevant data, views, or arguments about this proposed AD. Send your comments to an address listed under the ADDRESSES section. Include ‘‘Docket No. FAA–2011–0032; Directorate Identifier 2010–NM–236–AD’’ at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this proposed AD. We will consider all comments received by the closing date and may amend this proposed AD because of those comments. We will post all comments we receive, without change, to https:// www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this proposed AD. Discussion We issued an NPRM to amend 14 CFR part 39 to include an AD that would apply to The Boeing Company Model 737–600, –700, –700C, –800, and –900 series airplanes, as identified in Boeing Special Attention Service Bulletin 737– 30–1058, Revision 3, dated July 7, 2010. That NPRM published in the Federal Register on January 26, 2011 (76 FR 4567). That NPRM 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. Actions Since Previous NPRM (76 FR 4567, January 26, 2011) Was Issued Since we issued the previous NPRM (76 FR 4567, January 26, 2011), we have received three reports by operators of wire connectors at the two ends of the coil cord rubbing each other. These operators had accomplished the actions described in Boeing Special Attention Service Bulletin 737–30–1058, Revision 3, dated July 7, 2010 (or earlier revisions), which was referred to in the previous NPRM as the appropriate source of service information. The rub condition occurs when the window opens or is in the fully open position. The rub condition can possibly cause damage to the wire connector and the coil cord and cause arcing, smoke, and fire in the flight deck, which could lead to injuries to or incapacitation of the E:\FR\FM\17JYP1.SGM 17JYP1 41932 Federal Register / Vol. 77, No. 137 / Tuesday, July 17, 2012 / Proposed Rules flightcrew. As a result of these findings, Boeing has issued Special Attention Service Bulletin 737–30–1058, Revision 4, dated November 3, 2011, to correct the rubbing condition. The SNPRM will specify Special Attention Service Bulletin 737–30–1058, Revision 4, dated November 3, 2011 as the appropriate source of service information for accomplishing the proposed actions. This SNPRM also adds airplanes to the applicability, which includes Model 737–900ER airplanes and airplanes that have accomplished the actions of Boeing Special Attention Service Bulletin 737–30–1058, Revision 3, dated July 7, 2010, in production. Comments We gave the public the opportunity to comment on the previous NPRM (76 FR 4567, January 26, 2011). The following presents the comments received on the NPRM and the FAA’s response to each comment. Support for Previous NPRM (76 FR 4567, January 26, 2011) American Airlines (American) and Delta Airlines (Delta) stated they have no objections to the previous NPRM (76 FR 4567, January 26, 2011). Request To Use Revised Clocking Positions Boeing requested that clocking of the connectors for the left window be changed to the 9 o’clock position, and the 3 o’clock position for the right window. Boeing stated that this will provide better separation between the two ends of the coiled cord when the windows are in the open position. Boeing stated that Special Attention Service Bulletin 737–30–1058, Revision 3, dated July 7, 2010, will be revised to reflect this change. We agree. The proposed change prevents coil cord damage resulting from the close proximity of the two ends of the cord when the windows are in the open position. Without this change, the unsafe condition that originally prompted the previous NPRM (76 FR 4567, January 26, 2011) would not be corrected. We have changed the SNPRM to reference the actions specified in Boeing Special Attention Service Bulletin 737–30–1058, Revision 4, dated November 3, 2011. Request To Revise Certain Service Information American stated that Paragraph 1.K.1. of Boeing Special Attention Service Bulletin 737–30–1058, Revision 3, dated July 7, 2010, states that the only affected publication is the Boeing Model 737 illustrated parts catalog (IPC). But American pointed out that the wiring diagram manual (WDM) also needs to be revised, because Figures 2 and 7 of Boeing Special Attention Service Bulletin 737–30–1058, Revision 3, dated July 7, 2010, show the new wiring diagram after the installation of the new coil cord assembly. We agree that the WDM is affected by wiring changes shown in Figures 2 and 7 of Boeing Special Attention Service Bulletin 737–30–1058, Revision 3, dated July 7, 2010. As previously described, we have updated this supplemental NPRM to refer to Boeing Special Attention Service Bulletin 737–30– 1058, Revision 4, dated November 3, 2011. Paragraph 1.K.1. of that service bulletin does include the WDM as an affected reference. Request To Revise Service Information Reference American stated that, in Figures 4 and 9 of Boeing Special Attention Service Bulletin 737–30–1058, Revision 3, dated July 7, 2010, Section 20–10–11 of the standard wiring practices manual (SWPM) is referenced as an accepted procedure for adjusting the connector keyway if it needs to be re-clocked. American pointed out that this SWPM section does mention connectors, but does not reference clocking of keyways. Therefore, the more appropriate reference would be Section 20–60–06 of the SWPM, which covers the installation of electrical connectors. We agree that Section 20–10–11 of the SWPM does not provide instructions for setting the keyway or re-clocking the connectors. Those instructions are included in Section 20–60–06 of the SWPM. However, re-clocking or resetting the connector keyway is a misnomer of the intended action. According to Boeing, the intended action in Figures 4 and 9 of Boeing Special Attention Service Bulletin 737– 30–1058, Revision 3, dated July 7, 2010, is the repositioning of the connector, not re-clocking or resetting the connector keyway. Boeing Special Attention Service Bulletin 737–30–1058, Revision 4, dated November 3, 2011, deletes the wording ‘‘re-clocking or resetting the connector keyway,’’ and replaces it with text more clearly describing the intended action. As explained previously, we have changed the SNPRM to reference Boeing Special Attention Service Bulletin 737–30– 1058, Revision 4, dated November 3, 2011. FAA’s Determination We are proposing this SNPRM 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. Certain changes described above expand the scope of the previous NPRM (76 FR 4567, January 26, 2011). As a result, we have determined that it is necessary to reopen the comment period to provide additional opportunity for the public to comment on this SNPRM. Costs of Compliance We estimate that this proposed AD will affect 712 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: ESTIMATED COSTS Cost per product Cost on U.S. operators mstockstill on DSK4VPTVN1PROD with PROPOSALS Labor cost Keyway inspection and installation of new cord assemblies on both sides of the flight deck (Group 1, Configuration 1 airplanes). Adjustment of receptacles on both sides of the flight deck (Group 1, Configuration 1, and Group 2 airplanes). 6 work-hours × $85 per hour = $510. $1,608 $2,118 712 $1,508,016 4 work-hours × $85 per hour = $340. 0 340 404 137,360 According to the manufacturer, some of the costs of this proposed AD may be covered under warranty, thereby reducing the cost impact on affected VerDate Mar<15>2010 17:09 Jul 16, 2012 Jkt 226001 Parts cost Number of airplanes Action individuals. We do not control warranty coverage for affected individuals. As a result, we have included all costs in our cost estimate. PO 00000 Frm 00003 Fmt 4702 Sfmt 4702 Authority for This Rulemaking Title 49 of the United States Code specifies the FAA’s authority to issue E:\FR\FM\17JYP1.SGM 17JYP1 Federal Register / Vol. 77, No. 137 / Tuesday, July 17, 2012 / Proposed Rules 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 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 this 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.

SUMMARY: We are revising an earlier proposed airworthiness directive 
(AD) for certain The Boeing Company Model 737-600, -700, -700C, -800, 
and -900 series airplanes. That NPRM 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. That NPRM was prompted by 
reports of arcing and smoke at the left number 2 window in the flight 
deck. This action revises that NPRM by changing the keyway position of 
certain receptacle connectors and adding airplanes to the 
applicability. We are proposing this supplemental NPRM (SNPRM) to 
prevent arcing, smoke, and fire in the flight deck, which could lead to 
injuries to or incapacitation of the flightcrew. Since these actions 
impose an additional burden over that proposed in the NPRM, we are 
reopening the comment period to allow the public the chance to comment 
on these proposed changes.

DATES: We must receive comments on this supplemental NPRM by August 31, 
2012.

Discussion

    We issued an NPRM to amend 14 CFR part 39 to include an AD that 
would apply to The Boeing Company Model 737-600, -700, -700C, -800, and 
-900 series airplanes, as identified in Boeing Special Attention 
Service Bulletin 737-30-1058, Revision 3, dated July 7, 2010. That NPRM 
published in the Federal Register on January 26, 2011 (76 FR 4567). 
That NPRM 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.

Actions Since Previous NPRM (76 FR 4567, January 26, 2011) Was Issued

    Since we issued the previous NPRM (76 FR 4567, January 26, 2011), 
we have received three reports by operators of wire connectors at the 
two ends of the coil cord rubbing each other. These operators had 
accomplished the actions described in Boeing Special Attention Service 
Bulletin 737-30-1058, Revision 3, dated July 7, 2010 (or earlier 
revisions), which was referred to in the previous NPRM as the 
appropriate source of service information. The rub condition occurs 
when the window opens or is in the fully open position. The rub 
condition can possibly cause damage to the wire connector and the coil 
cord and cause arcing, smoke, and fire in the flight deck, which could 
lead to injuries to or incapacitation of the

[[Page 41932]]

flightcrew. As a result of these findings, Boeing has issued Special 
Attention Service Bulletin 737-30-1058, Revision 4, dated November 3, 
2011, to correct the rubbing condition. The SNPRM will specify Special 
Attention Service Bulletin 737-30-1058, Revision 4, dated November 3, 
2011 as the appropriate source of service information for accomplishing 
the proposed actions.
    This SNPRM also adds airplanes to the applicability, which includes 
Model 737-900ER airplanes and airplanes that have accomplished the 
actions of Boeing Special Attention Service Bulletin 737-30-1058, 
Revision 3, dated July 7, 2010, in production.

Comments

    We gave the public the opportunity to comment on the previous NPRM 
(76 FR 4567, January 26, 2011). The following presents the comments 
received on the NPRM and the FAA's response to each comment.

Support for Previous NPRM (76 FR 4567, January 26, 2011)

    American Airlines (American) and Delta Airlines (Delta) stated they 
have no objections to the previous NPRM (76 FR 4567, January 26, 2011).

Request To Use Revised Clocking Positions

    Boeing requested that clocking of the connectors for the left 
window be changed to the 9 o'clock position, and the 3 o'clock position 
for the right window. Boeing stated that this will provide better 
separation between the two ends of the coiled cord when the windows are 
in the open position. Boeing stated that Special Attention Service 
Bulletin 737-30-1058, Revision 3, dated July 7, 2010, will be revised 
to reflect this change.
    We agree. The proposed change prevents coil cord damage resulting 
from the close proximity of the two ends of the cord when the windows 
are in the open position. Without this change, the unsafe condition 
that originally prompted the previous NPRM (76 FR 4567, January 26, 
2011) would not be corrected. We have changed the SNPRM to reference 
the actions specified in Boeing Special Attention Service Bulletin 737-
30-1058, Revision 4, dated November 3, 2011.

Request To Revise Certain Service Information

    American stated that Paragraph 1.K.1. of Boeing Special Attention 
Service Bulletin 737-30-1058, Revision 3, dated July 7, 2010, states 
that the only affected publication is the Boeing Model 737 illustrated 
parts catalog (IPC). But American pointed out that the wiring diagram 
manual (WDM) also needs to be revised, because Figures 2 and 7 of 
Boeing Special Attention Service Bulletin 737-30-1058, Revision 3, 
dated July 7, 2010, show the new wiring diagram after the installation 
of the new coil cord assembly.
    We agree that the WDM is affected by wiring changes shown in 
Figures 2 and 7 of Boeing Special Attention Service Bulletin 737-30-
1058, Revision 3, dated July 7, 2010. As previously described, we have 
updated this supplemental NPRM to refer to Boeing Special Attention 
Service Bulletin 737-30-1058, Revision 4, dated November 3, 2011. 
Paragraph 1.K.1. of that service bulletin does include the WDM as an 
affected reference.

Request To Revise Service Information Reference

    American stated that, in Figures 4 and 9 of Boeing Special 
Attention Service Bulletin 737-30-1058, Revision 3, dated July 7, 2010, 
Section 20-10-11 of the standard wiring practices manual (SWPM) is 
referenced as an accepted procedure for adjusting the connector keyway 
if it needs to be re-clocked. American pointed out that this SWPM 
section does mention connectors, but does not reference clocking of 
keyways. Therefore, the more appropriate reference would be Section 20-
60-06 of the SWPM, which covers the installation of electrical 
connectors.
    We agree that Section 20-10-11 of the SWPM does not provide 
instructions for setting the keyway or re-clocking the connectors. 
Those instructions are included in Section 20-60-06 of the SWPM. 
However, re-clocking or resetting the connector keyway is a misnomer of 
the intended action. According to Boeing, the intended action in 
Figures 4 and 9 of Boeing Special Attention Service Bulletin 737-30-
1058, Revision 3, dated July 7, 2010, is the repositioning of the 
connector, not re-clocking or resetting the connector keyway. Boeing 
Special Attention Service Bulletin 737-30-1058, Revision 4, dated 
November 3, 2011, deletes the wording ``re-clocking or resetting the 
connector keyway,'' and replaces it with text more clearly describing 
the intended action. As explained previously, we have changed the SNPRM 
to reference Boeing Special Attention Service Bulletin 737-30-1058, 
Revision 4, dated November 3, 2011.

FAA's Determination

    We are proposing this SNPRM 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. 
Certain changes described above expand the scope of the previous NPRM 
(76 FR 4567, January 26, 2011). As a result, we have determined that it 
is necessary to reopen the comment period to provide additional 
opportunity for the public to comment on this SNPRM.

Costs of Compliance

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

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                     Cost per        Number of     Cost on U.S.

 both sides of the flight deck   $85 per hour =
 (Group 1, Configuration 1,      $340.
 and Group 2 airplanes).
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, some of the costs of this proposed 
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

[[Page 41933]]

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 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 this 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.
