Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Supplemental notice of proposed rulemaking (NPRM); reopening of 
comment period.

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

SUMMARY: We are revising an earlier proposed airworthiness directive 
(AD) for certain The Boeing Company Model 737-300, -400, -500, -600, -
700, -700C, -800, -900, and -900ER series airplanes. The NPRM proposed 
to require installing a new tail strobe light housing and a new 
disconnect bracket, and changing the wire bundles. The NPRM was 
prompted by a review of the tail strobe light installation, which 
revealed that the tail strobe light is not electrically bonded to 
primary structure of the airplane. This action revises the NPRM by 
adding, for certain airplanes, an inspection to determine if sealant is 
applied and corrective actions if necessary. We are proposing this 
supplemental NPRM (SNPRM) to prevent, in case of a direct lightning 
strike to the tail strobe light, damage to the operation of other 
critical airplane systems due to electromagnetic coupling and large 
transient voltages, and damage to the control mechanisms or surfaces 
due to a fire, which could result in loss of control of the airplane. 
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 SNPRM by April 28, 2014.

Discussion

    We issued an NPRM to amend 14 CFR part 39 by adding an AD that 
would apply to certain The Boeing Company Model 737-300, -400, -500, -
600, -700, -700C, -800, -900, and -900ER series airplanes. The NPRM 
published in the Federal Register on September 6, 2012 (77 FR 54848). 
The NPRM proposed to require installing a new tail strobe light housing 
and a new disconnect bracket, and changing the wire bundles.

Actions Since Previous NPRM (77 FR 54848, September 6, 2012) Was Issued

    Since we issued the NPRM (77 FR 54848, September 6, 2012), we have 
reviewed Boeing Special Attention Service Bulletin 737-33-1146, 
Revision 1, dated July 9, 2013. We referred to Boeing Special Attention 
Service Bulletin 737-33-1146, dated November 2, 2011, as the 
appropriate source of service information for accomplishing certain 
actions specified in the NPRM.
    Boeing Special Attention Service Bulletin 737-33-1146, Revision 1, 
dated July 9, 2013, adds procedures for airplanes on which the actions 
specified in Boeing Special Attention Service Bulletin 737-33-1146, 
dated November 2, 2011, have been done, for a general visual inspection 
to ensure there is fillet sealant between the disconnect bracket and 
the receptacle connector D44582J, and on the fasteners, and corrective 
actions if necessary. The corrective actions include applying sealant. 
Boeing Special Attention Service Bulletin 737-33-1146, Revision 1, 
dated July 9, 2013, also does the following:
     Incorporates the data given in Boeing Service Bulletin 
Information Notice 737-33-1146 IN 01, dated November 11, 2011, which 
changes Group 1, Configuration 1, to Group 1, and changes Group 1, 
Configuration 2, to Group 4.
     Improves the tail strobe light installation work 
instructions (adds an alternate work instruction to remove electrical 
power, adds an optional work instruction to improve access, adds the 
process specification for the installation of a blind insert, adds a 
new work instruction step, and figure, to do the drilling tasks before 
parts are cleaned for bonding, removes the undefined

[[Page 13935]]

cleaning method CM 3, and clarifies the required minimum clearance 
between the disconnect bracket and the adjacent station (STA) 1156 
bulkhead chord).
    We have revised paragraphs (c) and (g), and added new paragraph (h) 
to this SNPRM to refer to Boeing Special Attention Service Bulletin 
737-33-1146, Revision 1, dated July 9, 2013, and have redesignated 
subsequent paragraph identifiers accordingly.

Comments

    We gave the public the opportunity to comment on the NPRM (77 FR 
54848, September 6, 2012). The following presents the comments received 
on the NPRM and the FAA's response to each comment.

Concurrence With the NPRM (77 FR 54848, September 6, 2012)

    Boeing concurred with the NPRM (77 FR 54848, September 6, 2012).
    United Airlines (UAL) stated it has no objections to the proposed 
actions in the NPRM (77 FR 54848, September 6, 2012).

Clarification of Effect of Winglet Installation

    Aviation Partners Boeing stated that the installation of winglets 
per STC ST00830SE ([http://rgl.faa.gov/Regulatory--and--Guidance--
Library/rgstc.nsf/0/da95c49000906c7086257be80044d3d9/$FILE/
ST00830SE.pdf]) does not affect the accomplishment of the 
manufacturer's service instructions.
    We have added new paragraph (c)(3) to this final rule to state that 
installation of ST00830SE does not affect the ability to accomplish the 
actions required by this final rule. Therefore, for airplanes on which 
ST00830SE is installed, a ``change in product'' AMOC approval request 
is not necessary to comply with the requirements of 14 CFR 39.17.

Request To Include an Additional Action To Remove the Tail Cone and 
Adjust the Costs Accordingly

    American Airlines (AAL) requested that we revise the NPRM (77 FR 
54848, September 6, 2012), to include an additional action to remove 
the tail cone and also adjust the cost section for this action. AAL 
explained that due to the small size of the tail cone and additional 
equipment installed in this area, adequate clearance to install the 
bracket and associated wiring is problematic without removal of the 
tail cone. AAL reasoned that removing the tail cone could increase the 
labor requirement by up to 50 man-hours.
    We partially agree with AAL's request, since Boeing has revised the 
service information to add an optional work instruction step to remove 
and keep the tail cone if necessary. We have revised paragraph (g) of 
this SNPRM to refer to Boeing Special Attention Service Bulletin 737-
33-1146, Revision 1, dated July 9, 2013.
    We disagree with the request to revise the Cost of Compliance 
section of this SNPRM. Removing the tail cone is optional and we have 
no way of determining how many operators will choose to do that action. 
The economic analysis of this SNPRM is limited only to the cost of 
actions proposed to be required and is based on the costs provided in 
Boeing Special Attention Service Bulletin 737-33-1146, Revision 1, 
dated July 9, 2013. No change has been made to this SNPRM in this 
regard.

Request for Use of Shield Splice in Lieu of Solder Sleeve

    AAL requested that we revise the NPRM (77 FR 54848, September 6, 
2012), to allow for use of the shield splice contained in splice kit D-
150-0168 in lieu of solder sleeve BACS13CT3C. AAL explained that Figure 
8, Flag Notes 3 and 9, of Boeing Special Attention Service Bulletin 
737-33-1146, dated November 2, 2011, provides instructions to install a 
solder sleeve (BACS13CT3C) and splice kit (D-150-0168), respectively. 
AAL reasoned that splice kit D-150-0168 contains all of the required 
parts to properly splice the specified BMS 13-48 Type 12 wire, and that 
splice kit D-150-0168 is a much cleaner installation, maintains 
continuity of the existing shield, and is approved as a standard 
practice in Boeing Standard Wiring Practices Manual (SWPM) D6-54446, 
Section 20-30-12.
    We agree to allow for use of the shield splice contained in splice 
kit D-150-0168 in lieu of solder sleeve BACS13CT3C. Figure 8, Flag Note 
3, of Boeing Special Attention Service Bulletin 737-33-1146, dated 
November 2, 2011, specifies to add shielded ground wires. Solder sleeve 
BACS13CT3C supplied in the wire kit comes with a built-in ground-wire 
for an easier installation. Splice kit D-150-0168 does not have a 
ground wire. Therefore, if operators still want to supply the ground 
wires, Boeing SWPM 20-10-15, referenced in Figure 8, Flag Note 3, of 
Boeing Special Attention Service Bulletin 737-33-1146, dated November 
2, 2011, has the wire type information for the ground wires. We have 
added this exception to new paragraph (g)(1) of this SNPRM and added a 
note to paragraph (g)(1) of this SNPRM to include a reference to the 
SWPM.

Clarification of Typographical Error in the Service Information

    The second sentence of note (c) of Figure 3 of the Accomplishment 
Instructions of Boeing Special Attention Service Bulletin 737-33-1146, 
Revision 1, dated July 9, 2013, contains a typographical error and 
should instead read, ``Maintain a minimum of 1.7 diameter fastener edge 
margin on the disconnect bracket and the stiffener.'' We have included 
the correct information in new paragraph (g)(2) of this SNPRM.

Removal of Concurrent Requirements

    Paragraph (h) of the NPRM (77 FR 54848, September 6, 2012) proposed 
to require concurrent installation of wingtips and tail strobe lights. 
However, the service information identified in paragraph (h) of the 
NPRM is conditional service information and is not required by this 
SNPRM.

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 these same type 
designs. Certain changes described above expand the scope of the NPRM 
(77 FR 54848, September 6, 2012). 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.

Proposed Requirements of This SNPRM

    This SNPRM would require, for certain airplanes, installing a new 
tail strobe light housing and a new disconnect bracket, and changing 
the wire bundles. This SNPRM would also require, for certain other 
airplanes, an inspection to determine if sealant is applied, and 
corrective actions if necessary.

Costs of Compliance

    We estimate that this proposed AD affects 1,433 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

    We estimate the following cost to apply sealant, based on the 
results of the proposed inspection. We have no way of determining the 
number of aircraft that might need this sealant application:

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

    The parts cost to apply sealant between the disconnect bracket and 
the receptacle connector D44582J, and on the fasteners is not included 
in the estimate. It is considered ``Parts & Materials Supplied by the 
Operator,'' which is referenced in Boeing Special Attention Service 
Bulletin 737-33-1146, Revision 1, dated July 9, 2013.
    According to the manufacturer, all 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 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

[[Page 13937]]

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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

The Boeing Company: Docket No. FAA-2012-0863; Directorate Identifier 
2012-NM-108-AD.

(a) Comments Due Date

    We must receive comments by April 28, 2014.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to The Boeing Company airplanes, certificated in 
any category, as identified in paragraphs (c)(1) and (c)(2) of this 
AD.
    (1) Model 737-300, -400, and -500 series airplanes, as 
identified in Boeing Special Attention Service Bulletin 737-33-1149, 
dated April 13, 2012.
    (2) Model 737-600, -700, -700C, -800, -900, and -900ER series 
airplanes, as identified in Boeing Special Attention Service 
Bulletin 737-33-1146, Revision 1, dated July 9, 2013.
    (3) Installation of Supplemental Type Certificate (STC) 
ST00830SE [(http://rgl.faa.gov/Regulatory--and--Guidance--Library/
rgstc.nsf/0/da95c49000906c7086257be80044d3d9/$FILE/ST00830SE.pdf)] 
does not affect the ability to accomplish the actions required by 
this AD. Therefore, for airplanes on which STC ST00830SE 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.

(d) Subject

    Air Transport Association (ATA) of America Code 33, Lights.

(e) Unsafe Condition

    This AD was prompted by a review of the tail strobe light 
installation, which revealed that the tail strobe light is not 
electrically bonded to primary structure of the airplane. We are 
issuing this AD to prevent, in case of a direct lightning strike to 
the tail strobe light, damage to the operation of other critical 
airplane systems due to electromagnetic coupling and large transient 
voltages, and damage to the control mechanisms or surfaces due to a 
fire, which could result in loss of control of the airplane.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Tail Strobe Light Installation for Model 737-600, -700, -700C, -
800, -900, and -900ER Series Airplanes

    For Model 737-600, -700, -700C, -800, -900, and -900ER series 
airplanes on which the actions specified in Boeing Special Attention 
Service Bulletin 737-33-1146, dated November 2, 2011, have not been 
done before the effective date of this AD: Within 72 months after 
the effective date of this AD, install a new tail strobe light 
housing, install a new disconnect bracket, and change the wire 
bundles, in accordance with Part 1 of the Accomplishment 
Instructions of Boeing Special Attention Service Bulletin 737-33-
1146, Revision 1, dated July 9, 2013, except as required by 
paragraphs (g)(1) and (g)(2) of this AD.
    (1) Where Figure 8, Flag Note 3, of Boeing Special Attention 
Service Bulletin 737-33-1146, Revision 1, dated July 9, 2013, refers 
to solder sleeve BACS13CT3C, the shield splice contained in splice 
kit D-150-0168 may be used in lieu of solder sleeve (BACS13CT3C), 
provided a ground wire is used.
    Note 1 to paragraph (g)(1) of this AD: Guidance for wire-type 
information for the ground wires may be found in Boeing Standard 
Wiring Practices Manual (SWPM) D6-54446, Section 20-10-15.
    (2) Where the second sentence of note (c) of Figure 3 of the 
Accomplishment Instructions of Boeing Special Attention Service 
Bulletin 737-33-1146, Revision 1, dated July 9, 2013, specifies to 
``Maintain a minimum of 1.7 Dimensions fastener edge margin on the 
disconnect bracket and the stiffener,'' instead ``Maintain a minimum 
of 1.7 diameter fastener edge margin on the disconnect bracket and 
the stiffener.''

(h) Sealant Installation for Model 737-600, -700, -700C, -800, -900, 
and -900ER Series Airplanes

    For Model 737-600, -700, -700C, -800, -900, and -900ER series 
airplanes, on which the actions specified in Boeing Special 
Attention Service Bulletin 737-33-1146, dated November 2, 2011, have 
been done before the effective date of this AD: Within 72 months 
after the effective date of this AD, do a general visual inspection 
to ensure there is fillet sealant between the disconnect bracket and 
the receptacle connector D44582J, and on the fasteners, and do all 
applicable corrective actions, in accordance with Part 2 of the 
Accomplishment Instructions of Boeing Special Attention Service
