SUPPLEMENTARY INFORMATION: sroberts on DSK5SPTVN1PROD with RULES Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. The NPRM published in the Federal Register on September 24, 2012 (77 FR 58791). The NPRM proposed to require revising the maintenance program to update inspection requirements to detect fatigue cracking of PSEs. VerDate Mar<15>2010 15:47 Oct 02, 2013 Jkt 232001 Comments We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the proposal (77 FR 58791, September 24, 2012) and the FAA’s response to each comment. Requests To Use the Most Recent MPD Document Boeing and American Airlines (AAL) requested that the most recent MPD document be incorporated into the NPRM (77 FR 58791, September 24, 2012). Boeing stated that the NPRM (77 FR 58791, September 24, 2012) should reference Subsection B, AWLs— Structural Inspections, of Section 9, ‘‘Airworthiness Limitations (AWLs) and Certification Maintenance Requirements (CMRs),’’ of Boeing 737–600, –700, –700C, –800, –900, and –900ER MPD Document, D626A001–CMR, Revision December 2011. Boeing stated that this is the most recent MPD document and that this revision incorporates more stringent restrictions that should be included before the final rule is issued. AAL stated that the Relevant Service Information section and paragraph (g) of the NPRM (77 FR 58791, September 24, 2012) refer to Subsection B, AWLs— Structural Inspections, of Section 9, ‘‘Airworthiness Limitations (AWLs) and Certification Maintenance Requirements (CMRs),’’ of Boeing 737–600, –700, –700C, –800, –900, and –900ER MPD Document, D626A001–CMR, Revision July 2011. AAL stated that the most recent revision of that document is Revision August 2012, and that it should be incorporated into the NPRM. We agree with the commenters’ requests. The Relevant Service Information section of the NPRM (77 FR 58791, September 24, 2012) is not restated in the final rule. However, we have added both Revision December 2011 and Revision August 2012 of Subsection B, AWLs—Structural Inspections, of Section 9, ‘‘Airworthiness Limitations (AWLs) and Certification Maintenance Requirements (CMRs),’’ of Boeing 737–600, –700, –700C, –800, –900, and –900ER MPD Document, D626A001–CMR to paragraph (g) of this AD as acceptable options for doing the actions required by this AD. We also re-organized paragraph (g) of this AD to improve readability. Because Revision August 2012 of Subsection B, AWLs—Structural Inspections, of Section 9, ‘‘Airworthiness Limitations (AWLs) and Certification Maintenance Requirements (CMRs),’’ of Boeing 737–600, –700, –700C, –800, –900, and –900ER MPD PO 00000 Frm 00022 Fmt 4700 Sfmt 4700 Document, D626A001–CMR is a more stringent document, we might consider future rulemaking to require the actions specified in that document. Request To Use Later Revisions of the Service Information All Nippon Airways (ANA) requested the use of a later-approved MPD document. ANA noted that the NPRM (77 FR 58791, September 24, 2012) refers to Subsection B, AWLs— Structural Inspections, of Section 9, ‘‘Airworthiness Limitations (AWLs) and Certification Maintenance Requirements (CMRs),’’ of Boeing 737–600, –700, –700C, –800, –900, and –900ER MPD Document, D626A001–CMR, Revision July 2011, and that the current document is Revision December 2011. ANA stated that once the NPRM becomes a final rule, an alternative method of compliance (AMOC) will be necessary to do the actions in the latest document. ANA also stated that airworthiness limitations and CMR documents are revised periodically; if an AMOC is necessary for each revision of the document, it will burden the operators. ANA stated that if paragraph (g) of the NPRM addresses ‘‘D626A001– CMR revision July 2011, or later,’’ then an AMOC will not be necessary for each later revision of the document. ANA stated that, since the document is reviewed by the FAA prior to public release, the FAA is able to confirm if the document meets the adequate level of safety. We disagree with ANA’s request. We cannot use the phrase, ‘‘or later FAAapproved revisions,’’ in an AD when referring to the service document because doing so violates Office of the Federal Register (OFR) regulations for approval of materials ‘‘incorporated by reference’’ in rules. See 1 CFR 51.1(f). In general terms, we are required by OFR regulations to either publish the service document contents as part of the actual AD language; or submit the service document to the OFR for approval as ‘‘referenced’’ material, in which case we may only refer to such material in the text of an AD. The AD may refer to the service document only if the OFR approved it for ‘‘incorporation by reference.’’ See 1 CFR part 51. To allow operators to use later revisions of the referenced document (issued after publication of the AD), either we must revise the AD to reference specific later revisions, or operators must request approval to use later revisions as an AMOC with this AD under the provisions of paragraph (j)(1) of this AD. As stated previously, we have added Revision December 2011 E:\FR\FM\03OCR1.SGM 03OCR1 Federal Register / Vol. 78, No. 192 / Thursday, October 3, 2013 / Rules and Regulations and Revision August 2012 of Subsection B, AWLs—Structural Inspections, of Section 9, ‘‘Airworthiness Limitations (AWLs) and Certification Maintenance Requirements (CMRs),’’ of Boeing 737– 600, –700, –700C, –800, –900, and –900ER MPD Document, D626A001– CMR to paragraph (g) of this AD as acceptable options for doing the required actions. Requests for an AMOC Exception WestJet and AAL requested an AMOC exception. WestJet stated that in paragraph (c)(2) of the NPRM (77 FR 58791, September 24, 2012) the wording ‘‘may not be able to’’ implies that if an inspection to a modified, altered, or repaired area can be accomplished, then an AMOC is not required. WestJet also stated that an AMOC should not be required for Boeing repairs that have damage tolerant assessments and for supplemental type certificates (STCs) that have FAA-approved airworthiness limitation structural inspections. AAL stated that paragraph (c)(2) of the NPRM (77 FR 58791, September 24, 2012) provides minimal information on how operators should address new and existing repairs in a PSE area, as defined in Subsection B, AWLs—Structural Inspections, of Section 9, ‘‘Airworthiness Limitations (AWLs) and Certification Maintenance Requirements (CMRs),’’ of Boeing 737–600, –700, –700C, –800, –900, and –900ER MPD Document, D626A001–CMR, Revision July 2011. AAL also stated that all repairs in a PSE area that hide a portion of the inspection area will need an alternate inspection method approved by the Seattle Aircraft Certification Office to ensure continued damage tolerance of the affected structure. AAL stated that the current process will create an unnecessary burden on operators. AAL said that repairs approved under section 25.571(b) or 26.43(d) of the Federal Aviation Regulations (14 CFR 25.571(b) and 14 CFR 26.43(d), respectively) would provide the required level of safety for the continued damage tolerance of the affected structure for the NPRM. We disagree with the commenters’ requests. The revised set of inspections in Subsection B, AWLs—Structural Inspections, of Section 9, ‘‘Airworthiness Limitations (AWLs) and Certification Maintenance Requirements (CMRs),’’ of Boeing 737–600, –700, –700C, –800, –900, and –900ER MPD Document, D626A001–CMR, Revision July 2011, resulted from an updated analysis of The Boeing Company Model 737–600, –700, –700C, –800, –900, and –900ER series airplanes. The analysis includes consideration of updated loads and flight lengths that increase the stresses on the structure. Previously approved repairs, modifications, and alterations may not include consideration of the updated analysis, and therefore, a review is required before an AMOC can be issued for them. Affected operators, however, may request approval of an AMOC under the provisions of paragraph (j)(1) of this AD by submitting data substantiating that the change would provide an acceptable level of safety. We have not changed this final rule in this regard. Request To Reference Different Advisory Circular (AC) AAL requested that the NPRM (77 FR 58791, September 24, 2012) reference a different AC. AAL stated that paragraph (c)(2) of the NPRM provides FAA guidance for determining the changes necessary for the required inspections to satisfy the continued damage tolerance of the affected structure. AAL stated that the NPRM references FAA AC 25.1529– 1A, dated November 20, 2007 (http:// www.faa.gov/documentLibrary/media/ Advisory_Circular/AC%2025.15291A.pdf), for guidance regarding alternative inspection procedures; however, AC 25.1529–1A, dated November 20, 2007, applies only to airplanes that have a passenger seating capacity of less than 30 and a maximum payload capacity of less than 7,500 pounds. AAL stated that FAA AC 120– 93, dated November 20, 2007 (http:// rgl.faa.gov/Regulatory_and_Guidance_ Library/rgAdvisoryCircular.nsf/0/ f73fd2a31b353a71862573b000521928/ $FILE/AC%20120-93.pdf), refers to the damage tolerance inspection for repairs and alteration. We agree with the commenter’s request. We have revised paragraph (c)(2) of this AD by specifying FAA AC 120–93, dated November 20, 2007 (http://rgl.faa.gov/Regulatory_and_ 61175 Guidance_Library/ rgAdvisoryCircular.nsf/0/ f73fd2a31b353a71862573b000521928/ $FILE/AC%20120-93.pdf), in lieu of FAA AC 25.1529–1A, dated November 20, 2007 (http://www.faa.gov/ documentLibrary/media/Advisory_ Circular/AC%2025.1529-1A.pdf.) STC Comment Aviation Partners Boeing stated that the installation of winglets per STC ST00830SE (http://rgl.faa.gov/ Regulatory_and_Guidance_Library/ rgstc.nsf/0/ 408e012e008616a7862578880060456c/ $FILE/ST00830SE.pdf) affects the accomplishment of the manufacturer’s service instructions. We have added paragraph (c)(3) of this AD to state that installation of STC ST00830SE (http://rgl.faa.gov/ Regulatory_and_Guidance_Library/ rgstc.nsf/0/ 408e012e008616a7862578880060456c/ $FILE/ST00830SE.pdf) affects the ability to accomplish the actions required by this AD. Therefore, for airplanes on which STC ST00830SE is installed, a ‘‘change in product’’ AMOC approval request might be necessary to comply with the requirements of 14 CFR 39.17. Conclusion We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting this AD with the changes described previously— and minor editorial changes. We have determined that these minor changes: • Are consistent with the intent that was proposed in the NPRM (77 FR 58791, September 24, 2012) for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM (77 FR 58791, September 24, 2012). 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 1,200 airplanes of U.S. registry. We estimate the following costs to comply with this AD: sroberts on DSK5SPTVN1PROD with RULES ESTIMATED COSTS Action Labor cost Parts cost Cost per product Cost on U.S. operators Document Revision ............................................... 1 work-hour × $85 per hour = $85 ....................... $0 $85 $102,000 VerDate Mar<15>2010 15:47 Oct 02, 2013 Jkt 232001 PO 00000 Frm 00023 Fmt 4700 Sfmt 4700 E:\FR\FM\03OCR1.SGM 03OCR1 61176 Federal Register / Vol. 78, No. 192 / Thursday, October 3, 2013 / Rules and Regulations Paperwork Reduction Act A federal agency may not conduct or sponsor, and a person is not required to respond to, nor shall a person be subject to a penalty for failure to comply with a collection of information subject to the requirements of the Paperwork Reduction Act unless that collection of information displays a current valid OMB Control Number. The OMB Control Number for this information collection is 2120–0056. Public reporting for this collection of information is estimated to be approximately 5 minutes per response, including the time for reviewing instructions, completing and reviewing the collection of information. All responses to this collection of information are mandatory. Comments concerning the accuracy of this burden and suggestions for reducing the burden should be directed to the FAA at: 800 Independence Ave. SW., Washington, DC 20591, Attn: Information Collection Clearance Officer, AES–200. sroberts on DSK5SPTVN1PROD with RULES 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, (2) Is not a ‘‘significant rule’’ under DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979), VerDate Mar<15>2010 15:47 Oct 02, 2013 Jkt 232001 (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. Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1. The authority citation for part 39 continues to read as follows: ■ Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 [Amended] 2. The FAA amends § 39.13 by adding the following new airworthiness directive (AD): ■ 2013–19–23 The Boeing Company: Amendment 39–17605 ; Docket No. FAA–2012–0998; Directorate Identifier 2011–NM–249–AD. (a) Effective Date This AD is effective November 7, 2013. (b) Affected ADs None. (c) Applicability (1) This AD applies to the Boeing Company Model 737–600, –700, –700C, –800, –900, and –900ER series airplanes, certificated in any category, with an original airworthiness certificate or original export certificate of airworthiness issued before April 3, 2012. (2) This AD requires revisions to certain operator maintenance documents to include new inspections. Compliance with these inspections is required by 14 CFR 91.403(c). For airplanes that have been previously modified, altered, or repaired in the areas addressed by these inspections, the operator may not be able to accomplish the inspections described in the revisions. In this situation, to comply with 14 CFR 91.403(c), the operator must request approval for an alternative method of compliance (AMOC) according to paragraph (j) of this AD. The request should include a description of changes to the required inspections that will ensure the continued damage tolerance of the affected structure. The FAA has provided guidance for this determination in FAA Advisory Circular (AC) 120–93, dated November 20, 2007 (http://rgl.faa.gov/ Regulatory_and_Guidance_Library/ rgAdvisoryCircular.nsf/0/ f73fd2a31b353a71862573b000521928/$FILE/ AC%20120-93.pdf).

(e) Unsafe Condition This AD was prompted by a new revision to the airworthiness limitations of the maintenance planning data (MPD) document. We are issuing this AD to detect and correct fatigue cracking of various principal structural elements (PSEs), which could adversely affect the structural integrity of these airplanes. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Maintenance Program Revision (1) Within 12 months after the effective date of this AD, revise the maintenance program by incorporating the information in paragraph (g)(1)(i), (g)(1)(ii), or (g)(1)(iii) of this AD, except as provided by paragraph (h) of this AD.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an AD that would apply to the specified products. 
The NPRM published in the Federal Register on September 24, 2012 (77 FR 
58791). The NPRM proposed to require revising the maintenance program 
to update inspection requirements to detect fatigue cracking of PSEs.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the proposal 
(77 FR 58791, September 24, 2012) and the FAA's response to each 
comment.

Requests To Use the Most Recent MPD Document

    Boeing and American Airlines (AAL) requested that the most recent 
MPD document be incorporated into the NPRM (77 FR 58791, September 24, 
2012).
    Boeing stated that the NPRM (77 FR 58791, September 24, 2012) 
should reference Subsection B, AWLs--Structural Inspections, of Section 
9, ``Airworthiness Limitations (AWLs) and Certification Maintenance 
Requirements (CMRs),'' of Boeing 737-600, -700, -700C, -800, -900, and 
-900ER MPD Document, D626A001-CMR, Revision December 2011. Boeing 
stated that this is the most recent MPD document and that this revision 
incorporates more stringent restrictions that should be included before 
the final rule is issued.
    AAL stated that the Relevant Service Information section and 
paragraph (g) of the NPRM (77 FR 58791, September 24, 2012) refer to 
Subsection B, AWLs--Structural Inspections, of Section 9, 
``Airworthiness Limitations (AWLs) and Certification Maintenance 
Requirements (CMRs),'' of Boeing 737-600, -700, -700C, -800, -900, and 
-900ER MPD Document, D626A001-CMR, Revision July 2011. AAL stated that 
the most recent revision of that document is Revision August 2012, and 
that it should be incorporated into the NPRM.
    We agree with the commenters' requests. The Relevant Service 
Information section of the NPRM (77 FR 58791, September 24, 2012) is 
not restated in the final rule. However, we have added both Revision 
December 2011 and Revision August 2012 of Subsection B, AWLs--
Structural Inspections, of Section 9, ``Airworthiness Limitations 
(AWLs) and Certification Maintenance Requirements (CMRs),'' of Boeing 
737-600, -700, -700C, -800, -900, and -900ER MPD Document, D626A001-CMR 
to paragraph (g) of this AD as acceptable options for doing the actions 
required by this AD. We also re-organized paragraph (g) of this AD to 
improve readability. Because Revision August 2012 of Subsection B, 
AWLs--Structural Inspections, of Section 9, ``Airworthiness Limitations 
(AWLs) and Certification Maintenance Requirements (CMRs),'' of Boeing 
737-600, -700, -700C, -800, -900, and -900ER MPD Document, D626A001-CMR 
is a more stringent document, we might consider future rulemaking to 
require the actions specified in that document.

Request To Use Later Revisions of the Service Information

    All Nippon Airways (ANA) requested the use of a later-approved MPD 
document. ANA noted that the NPRM (77 FR 58791, September 24, 2012) 
refers to Subsection B, AWLs--Structural Inspections, of Section 9, 
``Airworthiness Limitations (AWLs) and Certification Maintenance 
Requirements (CMRs),'' of Boeing 737-600, -700, -700C, -800, -900, and 
-900ER MPD Document, D626A001-CMR, Revision July 2011, and that the 
current document is Revision December 2011. ANA stated that once the 
NPRM becomes a final rule, an alternative method of compliance (AMOC) 
will be necessary to do the actions in the latest document. ANA also 
stated that airworthiness limitations and CMR documents are revised 
periodically; if an AMOC is necessary for each revision of the 
document, it will burden the operators. ANA stated that if paragraph 
(g) of the NPRM addresses ``D626A001-CMR revision July 2011, or 
later,'' then an AMOC will not be necessary for each later revision of 
the document. ANA stated that, since the document is reviewed by the 
FAA prior to public release, the FAA is able to confirm if the document 
meets the adequate level of safety.
    We disagree with ANA's request. We cannot use the phrase, ``or 
later FAA-approved revisions,'' in an AD when referring to the service 
document because doing so violates Office of the Federal Register (OFR) 
regulations for approval of materials ``incorporated by reference'' in 
rules. See 1 CFR 51.1(f).
    In general terms, we are required by OFR regulations to either 
publish the service document contents as part of the actual AD 
language; or submit the service document to the OFR for approval as 
``referenced'' material, in which case we may only refer to such 
material in the text of an AD. The AD may refer to the service document 
only if the OFR approved it for ``incorporation by reference.'' See 1 
CFR part 51.
    To allow operators to use later revisions of the referenced 
document (issued after publication of the AD), either we must revise 
the AD to reference specific later revisions, or operators must request 
approval to use later revisions as an AMOC with this AD under the 
provisions of paragraph (j)(1) of this AD. As stated previously, we 
have added Revision December 2011

[[Page 61175]]

and Revision August 2012 of Subsection B, AWLs--Structural Inspections, 
of Section 9, ``Airworthiness Limitations (AWLs) and Certification 
Maintenance Requirements (CMRs),'' of Boeing 737-600, -700, -700C, -
800, -900, and -900ER MPD Document, D626A001-CMR to paragraph (g) of 
this AD as acceptable options for doing the required actions.

Requests for an AMOC Exception

    WestJet and AAL requested an AMOC exception.
    WestJet stated that in paragraph (c)(2) of the NPRM (77 FR 58791, 
September 24, 2012) the wording ``may not be able to'' implies that if 
an inspection to a modified, altered, or repaired area can be 
accomplished, then an AMOC is not required. WestJet also stated that an 
AMOC should not be required for Boeing repairs that have damage 
tolerant assessments and for supplemental type certificates (STCs) that 
have FAA-approved airworthiness limitation structural inspections.
    AAL stated that paragraph (c)(2) of the NPRM (77 FR 58791, 
September 24, 2012) provides minimal information on how operators 
should address new and existing repairs in a PSE area, as defined in 
Subsection B, AWLs--Structural Inspections, of Section 9, 
``Airworthiness Limitations (AWLs) and Certification Maintenance 
Requirements (CMRs),'' of Boeing 737-600, -700, -700C, -800, -900, and 
-900ER MPD Document, D626A001-CMR, Revision July 2011. AAL also stated 
that all repairs in a PSE area that hide a portion of the inspection 
area will need an alternate inspection method approved by the Seattle 
Aircraft Certification Office to ensure continued damage tolerance of 
the affected structure. AAL stated that the current process will create 
an unnecessary burden on operators. AAL said that repairs approved 
under section 25.571(b) or 26.43(d) of the Federal Aviation Regulations 
(14 CFR 25.571(b) and 14 CFR 26.43(d), respectively) would provide the 
required level of safety for the continued damage tolerance of the 
affected structure for the NPRM.
    We disagree with the commenters' requests. The revised set of 
inspections in Subsection B, AWLs--Structural Inspections, of Section 
9, ``Airworthiness Limitations (AWLs) and Certification Maintenance 
Requirements (CMRs),'' of Boeing 737-600, -700, -700C, -800, -900, and 
-900ER MPD Document, D626A001-CMR, Revision July 2011, resulted from an 
updated analysis of The Boeing Company Model 737-600, -700, -700C, -
800, -900, and -900ER series airplanes. The analysis includes 
consideration of updated loads and flight lengths that increase the 
stresses on the structure. Previously approved repairs, modifications, 
and alterations may not include consideration of the updated analysis, 
and therefore, a review is required before an AMOC can be issued for 
them. Affected operators, however, may request approval of an AMOC 
under the provisions of paragraph (j)(1) of this AD by submitting data 
substantiating that the change would provide an acceptable level of 
safety. We have not changed this final rule in this regard.

Request To Reference Different Advisory Circular (AC)

    AAL requested that the NPRM (77 FR 58791, September 24, 2012) 
reference a different AC. AAL stated that paragraph (c)(2) of the NPRM 
provides FAA guidance for determining the changes necessary for the 
required inspections to satisfy the continued damage tolerance of the 
affected structure. AAL stated that the NPRM references FAA AC 25.1529-
1A, dated November 20, 2007 (http://www.faa.gov/documentLibrary/media/Advisory_Circular/AC%2025.1529-1A.pdf), for guidance regarding 
alternative inspection procedures; however, AC 25.1529-1A, dated 
November 20, 2007, applies only to airplanes that have a passenger 
seating capacity of less than 30 and a maximum payload capacity of less 
than 7,500 pounds. AAL stated that FAA AC 120-93, dated November 20, 
2007 (http://rgl.faa.gov/Regulatory--and--Guidance--Library/
rgAdvisoryCircular.nsf/0/f73fd2a31b353a71862573b000521928/$FILE/
AC%20120-93.pdf), refers to the damage tolerance inspection for repairs 
and alteration.
    We agree with the commenter's request. We have revised paragraph 
(c)(2) of this AD by specifying FAA AC 120-93, dated November 20, 2007 
(http://rgl.faa.gov/Regulatory--and--Guidance--Library/
rgAdvisoryCircular.nsf/0/f73fd2a31b353a71862573b000521928/$FILE/
AC%20120-93.pdf), in lieu of FAA AC 25.1529-1A, dated November 20, 2007 
(http://www.faa.gov/documentLibrary/media/Advisory_Circular/AC%2025.1529-1A.pdf.)

STC Comment

    Aviation Partners Boeing stated that the installation of winglets 
per STC ST00830SE (http://rgl.faa.gov/Regulatory--and--Guidance--
Library/rgstc.nsf/0/408e012e008616a7862578880060456c/$FILE/
ST00830SE.pdf) affects the accomplishment of the manufacturer's service 
instructions.
    We have added paragraph (c)(3) of this AD to state that 
installation of STC ST00830SE (http://rgl.faa.gov/Regulatory--and--
Guidance--Library/rgstc.nsf/0/408e012e008616a7862578880060456c/$FILE/
ST00830SE.pdf) affects the ability to accomplish the actions required 
by this AD. Therefore, for airplanes on which STC ST00830SE is 
installed, a ``change in product'' AMOC approval request might be 
necessary to comply with the requirements of 14 CFR 39.17.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
this AD with the changes described previously--and minor editorial 
changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM (77 FR 58791, September 24, 2012) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (77 FR 58791, September 24, 2012).
    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 1,200 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to a penalty for 
failure to comply with a collection of information subject to the 
requirements of the Paperwork Reduction Act unless that collection of 
information displays a current valid OMB Control Number. The OMB 
Control Number for this information collection is 2120-0056. Public 
reporting for this collection of information is estimated to be 
approximately 5 minutes per response, including the time for reviewing 
instructions, completing and reviewing the collection of information. 
All responses to this collection of information are mandatory. Comments 
concerning the accuracy of this burden and suggestions for reducing the 
burden should be directed to the FAA at: 800 Independence Ave. SW., 
Washington, DC 20591, Attn: Information Collection Clearance Officer, 
AES-200.

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,
    (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.

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 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):

2013-19-23 The Boeing Company: Amendment 39-17605 ; Docket No. FAA-
2012-0998; Directorate Identifier 2011-NM-249-AD.

(a) Effective Date

    This AD is effective November 7, 2013.

(b) Affected ADs

    None.

(c) Applicability

    (1) This AD applies to the Boeing Company Model 737-600, -700, -
700C, -800, -900, and -900ER series airplanes, certificated in any 
category, with an original airworthiness certificate or original 
export certificate of airworthiness issued before April 3, 2012.
    (2) This AD requires revisions to certain operator maintenance 
documents to include new inspections. Compliance with these 
inspections is required by 14 CFR 91.403(c). For airplanes that have 
been previously modified, altered, or repaired in the areas 
addressed by these inspections, the operator may not be able to 
accomplish the inspections described in the revisions. In this 
situation, to comply with 14 CFR 91.403(c), the operator must 
request approval for an alternative method of compliance (AMOC) 
according to paragraph (j) of this AD. The request should include a 
description of changes to the required inspections that will ensure 
the continued damage tolerance of the affected structure. The FAA 
has provided guidance for this determination in FAA Advisory 
Circular (AC) 120-93, dated November 20, 2007 (http://rgl.faa.gov/
Regulatory--and--Guidance--Library/rgAdvisoryCircular.nsf/0/
f73fd2a31b353a71862573b000521928/$FILE/AC%20120-93.pdf).
    (3) Installation of Supplemental Type Certificate (STC) 
ST00830SE (http://rgl.faa.gov/Regulatory--and--Guidance--Library/
rgstc.nsf/0/408e012e008616a7862578880060456c/$FILE/ST00830SE.pdf) 
affects the ability to accomplish the actions required by this AD. 
Therefore, for airplanes on which STC ST00830SE is installed, a 
``change in product'' AMOC approval request might be necessary to 
comply with the requirements of 14 CFR 39.17.

(d) Subject

    Joint Aircraft System Component (JASC)/Air Transport Association 
(ATA) of America Code 52, Doors; 53, Fuselage; 54, Nacelles/Pylons; 
55, Stabilizers; and 57, Wings.

(e) Unsafe Condition

    This AD was prompted by a new revision to the airworthiness 
limitations of the maintenance planning data (MPD) document. We are 
issuing this AD to detect and correct fatigue cracking of various 
principal structural elements (PSEs), which could adversely affect 
the structural integrity of these airplanes.

(f) Compliance

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

(g) Maintenance Program Revision

    (1) Within 12 months after the effective date of this AD, revise 
the maintenance program by incorporating the information in 
paragraph (g)(1)(i), (g)(1)(ii), or (g)(1)(iii) of this AD, except 
as provided by paragraph (h) of this AD.
    (i) Subsection B, AWLs--Structural Inspections, of Section 9, 
``Airworthiness Limitations (AWLs) and Certification Maintenance 
Requirements (CMRs),'' of Boeing 737-600, -700, -700C, -800, -900, 
and -900ER MPD Document, D626A001-CMR, Revision July 2011.
    (ii) Subsection B, AWLs--Structural Inspections, of Section 9, 
``Airworthiness Limitations (AWLs) and Certification Maintenance 
Requirements (CMRs),'' of Boeing 737-600, -700, -700C, -800, -900, 
and -900ER MPD Document, D626A001-CMR, Revision December 2011.
    (iii) Subsection B, AWLs--Structural Inspections, of Section 9, 
``Airworthiness Limitations (AWLs) and Certification Maintenance 
Requirements (CMRs),'' of Boeing 737-600, -700, -700C, -800, -900, 
and -900ER MPD Document, D626A001-CMR, Revision August 2012.
    (2) The initial compliance time for the inspections is within 
the applicable times specified in the documents identified in 
paragraphs (g)(1)(i), (g)(1)(ii), and (g)(1)(iii) of this AD, or 
within 18 months after the effective date of this AD, whichever 
occurs later; or within the applicable time specified in those 
documents from the time of installation of new parts.
    (3) Reports specified in the documents identified in paragraphs 
(g)(1)(i), (g)(1)(ii), and (g)(1)(iii) of this AD may be submitted 
within 10 days after the airplane is returned to service, instead of 
10 days after each individual finding as specified in Section 9 of 
the documents identified in paragraphs (g)(1)(i), (g)(1)(ii), and 
(g)(1)(iii) of this AD.

(h) No Alternative Inspections and Inspection Intervals

    After accomplishing the actions required by paragraph (g) of 
this AD, no alternative actions (i.e., alternative inspections) or 
inspection intervals may be used or incorporated unless the 
alternative action or interval is approved as an AMOC in accordance 
with the procedures specified in paragraph (j) of this AD.

(i) Paperwork Reduction Act Burden Statement

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to a penalty 
for failure to comply with a collection of information subject to 
the requirements of the Paperwork Reduction Act unless that 
collection of information displays a current valid OMB Control 
Number. The OMB Control Number for this information collection is 
2120-0056. Public reporting for this collection of information is 
estimated to be approximately 5 minutes per response, including the 
time for reviewing instructions, completing and reviewing the 
collection of information. All responses to this collection of 
information are mandatory. Comments concerning the accuracy of this 
burden and suggestions for reducing the burden should be directed to 
the FAA at: 800 Independence Ave. SW., Washington, DC 20591, Attn: 
Information Collection Clearance Officer, AES-200.

(j) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Seattle Aircraft Certification Office (ACO), 
ANM-120S, FAA, has the authority to approve AMOCs for this AD, if 
requested using the procedures found in 14 CFR 39.19. In accordance 
with 14 CFR 39.19, send your request to your principal inspector or 
local Flight Standards District Office, as appropriate. If sending 
information directly to the manager of the ACO, send it to the 
attention of the person identified in paragraph (k) of this AD. 
Information may be emailed to: 9-ANM-Seattle-ACO-AMOC-Requests@faa.gov.
    (2) Before using any approved AMOC, notify your appropriate 
principal inspector, or lacking a principal inspector, the manager 
of the local flight standards district office/certificate holding 
district office.
    (3) An AMOC that provides an acceptable level of safety may be 
used for any repair required in the area affected by this AD if it 
is approved by the Boeing Commercial Airplanes Organization 
Designation Authorization (ODA) that has been authorized by the 
Manager, Seattle ACO, to make those findings. For a repair method to 
be approved, the repair must meet the certification basis of the 
airplane, and the approval must specifically refer to this AD.
