Download as PDF Federal Register / Vol. 81, No. 219 / Monday, November 14, 2016 / Proposed Rules DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2015–3984; Directorate Identifier 2015–NM–033–AD] RIN 2120–AA64 Airworthiness Directives; The Boeing Company Airplanes Federal Aviation Administration (FAA), DOT. ACTION: Supplemental notice of proposed rulemaking (SNPRM); reopening of comment period. AGENCY: We are revising an earlier proposal to supersede Airworthiness Directive (AD) 2008–13–12 R1, for certain The Boeing Company Model 737–100, –200, –200C, –300, –400, and –500 series airplanes. AD 2008–13–12 R1 requires various repetitive inspections for cracking of the upperframe-to-side-frame splice of the fuselage, and other specified and corrective actions if necessary; and also provides for an optional preventive modification, which would terminate the repetitive inspections. This action revises the notice of proposed rulemaking (NPRM) by adding postrepair/post-modification inspections. We are proposing this SNPRM to detect and correct fatigue cracking of the upper-frame-to-side-frame splice of the fuselage, which could result in reduced structural integrity of the frame and adjacent lap joint, causing increased loading in the fuselage skin, which will accelerate skin crack growth and result in decompression 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 December 29, 2016. ADDRESSES: You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods: • Federal eRulemaking Portal: Go to http://www.regulations.gov.

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 supersede AD 2008–13–12 R1, Amendment 39–15719 (73 FR 67383, November 14, 2008) (‘‘AD 2008–13–12 R1’’). AD 2008–13–12 R1 applied to certain The Boeing Company Model 737–100, –200, –200C, –300, –400, and –500 series airplanes. AD 2008–13–12 R1 requires various repetitive inspections for cracking of the upperframe-to-side-frame splice of the fuselage, and other specified and corrective actions if necessary. AD 2008–13–12 R1 also provides for an optional preventive modification, which terminates the repetitive inspections. AD 2008–13–12 R1 resulted from a report that the upper frame of the fuselage was severed between stringers (S) S–13L and S–14L at station (STA) 747, and the adjacent frame at STA 767 had a 1.3-inch-long crack at the same stringer location. The NPRM published in the Federal Register on October 9, 2015 (80 FR 61133) (‘‘The NPRM’’). The NPRM was prompted by reports of additional fatigue cracking of the upperframe-to-side-frame splice of the fuselage, and one report of a severed frame. The NPRM proposed to add, for certain airplanes, an inspection to determine if the existing frame repair meets all specified requirements, and for certain other airplanes, a new modification of the upper-frame-to-sideframe splice, which would terminate the repetitive inspections. The NPRM also proposed to reduce certain inspection thresholds and repetitive intervals. Actions Since Previous NPRM Was Issued Since we issued the NPRM, we have determined that it is necessary to require post-repair/post-modification inspections that were not included in the NPRM. Related Service Information Under 1 CFR Part 51 We reviewed Boeing Alert Service Bulletin 737–53A1261, Revision 1, dated January 30, 2015. The service information describes procedures for various repetitive inspections for cracking of the upper-frame-to-sideframe splice of the fuselage, a preventive modification to prevent WFD, an inspection to determine if the existing frame repair meets all specified requirements, and corrective actions. This service information is reasonably available because the interested parties E:\FR\FM\14NOP1.SGM 14NOP1 79396 Federal Register / Vol. 81, No. 219 / Monday, November 14, 2016 / Proposed Rules have access to it through their normal course of business or by the means identified in the ADDRESSES section. Comments We gave the public the opportunity to comment on the NPRM. The following presents the comments received on the NPRM and the FAA’s response to each comment. One commenter supported the actions specified in the NPRM. Request To Require Post-Repair/PostModification Inspections Boeing asked that we change paragraph (j) of the proposed AD (in the NPRM) to require the post-repair/postmodification inspections that are not required in that paragraph. Boeing stated that the WFD evaluation of the frame repair/modification specified in Boeing Alert Service Bulletin 737– 53A1261, Revision 1, dated January 30, 2015, indicated the need for reduced repetitive inspection intervals from those provided in Boeing Damage Tolerance Inspection Data Service Bulletin 737–00–1006, dated March 12, 2010. Boeing added that since the inspections specified in Boeing Service Bulletin 737–00–1006, dated March 12, 2010, are not to be used for the postrepair/post-modification inspections required by 14 CFR 121.1109(c)(2) or 129.109(c)(2), they should be required by paragraph (j) of the proposed AD. We agree with the commenter for the reasons provided. We have changed paragraph (j) of this SNPRM to require that post-repair/post-modification inspections be done in accordance with the Accomplishment Instructions of Boeing Alert Service Bulletin 737– 53A1261, Revision 1, dated January 30, 2015. Lhorne on DSK30JT082PROD with PROPOSALS Effect of Winglets on Accomplishment of the Proposed Actions Aviation Partners Boeing stated that accomplishing the Supplemental Type Certificate (STC) ST01219SE does not affect the actions specified in the NPRM. We agree with the commenter. We have changed paragraph (c) of this proposed AD to state that installation of STC ST01219SE does not affect the ability to accomplish the actions required by this final rule. Therefore, for airplanes on which STC ST01219SE is installed, a ‘‘change in product’’ alternative methods of compliance (AMOC) approval request is not necessary to comply with the requirements of 14 CFR 39.17. VerDate Sep<11>2014 15:04 Nov 10, 2016 Jkt 241001 Request To Clarify That the NPRM Addresses WFD Boeing asked that we update the language in ‘‘Actions Since AD 2008– 13–12 R1, Amendment 39–15719 (73 FR 67383, November 14, 2008) Was Issued’’ section of the NPRM to clarify that this action is intended to address WFD by supporting the airplane’s limit of validity (LOV). Boeing noted that a recently issued WFD-related AD action used different language regarding WFD. Boeing stated that Boeing Alert Service Bulletin 737–53A1261, Revision 1, dated January 30, 2015, was released in support of the requirements of 14 CFR 26.21(b) and (c) and provides additional service action required to support LOV. We agree to provide clarification. The NPRM addressed WFD in several locations in the preamble. To clarify, this action is intended to address WFD by supporting the airplane’s LOV, as stated by Boeing. However, we have not updated the language in that section of the NPRM because that section of the NPRM is not carried over to this SNPRM. Therefore, no change to this SNPRM is necessary in this regard. Request To Clarify Certain Procedures in the Related Service Information Section Boeing asked that we change the ‘‘Related Service Information under 1 CFR part 51’’ section in the NPRM to clarify the description of the modification procedures in the service information. Boeing asked that the proposed language ‘‘. . . a new preventive modification, which would eliminate the need for the repetitive inspections’’ be changed to ‘‘. . . a preventive modification to prevent the WFD.’’ Boeing stated that Boeing Alert Service Bulletin 737–53A1261, Revision 1, dated January 30, 2015, retains all inspections specified in Boeing Alert Service Bulletin 737–53A1261, dated January 19, 2006, and mandates the previously optional preventive modification to mitigate the WFD concern. We agree with the commenter for the reasons provided. We have clarified the ‘‘Related Service Information under 1 CFR part 51’’ section of this SNPRM accordingly. Request To Clarify Reason for Supersedure Boeing asked that we clarify in the SUMMARY section of the NPRM the events that prompted the proposed supersedure of AD 2008–13–12 R1. Boeing stated that instead of two reports of severed frames, as specified in the NPRM, there was just one report of a severed frame. PO 00000 Frm 00003 Fmt 4702 Sfmt 4702 We agree to provide clarification. We agree that the commenter’s statement is accurate. However, we have removed details relating to the NPRM from the SUMMARY section of this SNPRM; therefore, no change is necessary to this SNPRM in this regard. Request To Clarify Provisions Related to Repetitive Actions Boeing asked that we clarify paragraph (g)(1)(ii) of the proposed AD (in the NPRM) to state that the actions are to be repeated until the preventive modification in paragraph (k) or the terminating action in paragraph (l) of the proposed AD has been accomplished. Boeing added that this change is consistent with the provisions of Boeing Alert Service Bulletin 737– 53A1261, Revision 1, dated January 30, 2015, and the requirements of AD 2008– 13–12 R1. We agree with the commenter for the reasons provided. We have clarified paragraph (g)(1)(ii) of this proposed AD accordingly. Request To Clarify Inspection Locations Boeing asked that we change paragraph (g)(2)(i) of the proposed AD (in the NPRM) to clarify that the inspections are for ‘‘existing frame repairs,’’ instead of ‘‘frames.’’ Boeing requested that we change ‘‘frame’’ to ‘‘frame repairs,’’ and ‘‘tied frames’’ to ‘‘existing frame repairs.’’ We agree with the commenter. We have revised paragraph (g)(2)(i) of this proposed AD accordingly. Request To Revise Inspection Type Boeing asked that we revise paragraphs (k) and (l) of the proposed AD (in the NPRM) by changing ‘‘detailed and HFEC inspections’’ to just ‘‘HFEC inspections.’’ Boeing stated that detailed inspections are not specified during accomplishment of the preventive modification in Boeing Alert Service Bulletin 737–53A1261, Revision 1, dated January 30, 2015. We agree with the commenter for the reason provided. We have removed ‘‘detailed’’ inspections from paragraphs (k) and (l) of this proposed AD. Request To Change Certain Language in Paragraph (l)(2) of the Proposed AD Boeing asked that we change paragraph (l)(2) of the proposed AD (in the NPRM), which stated that the repair would terminate the repetitive inspections required by paragraph (g)(1) of this AD. Boeing requested that the proposed AD instead state that the repair would terminate not only the repetitive inspections, but also the preventive modification required by E:\FR\FM\14NOP1.SGM 14NOP1 Federal Register / Vol. 81, No. 219 / Monday, November 14, 2016 / Proposed Rules Lhorne on DSK30JT082PROD with PROPOSALS paragraph (k) of the proposed AD. Boeing added that Boeing Alert Service Bulletin 737–53A1261, Revision 1, dated January 30, 2015, provides a terminating action provision for the repetitive inspections and the preventive modification under the repair. Boeing stated that accomplishment of the repair removes the WFD, and therefore the preventive modification is not required for repaired frames. We agree with the commenter for the reasons provided. We have clarified the language in paragraph (l)(2) of this proposed AD accordingly. Request To Move Terminating Action in Paragraph (l)(3) of the Proposed AD to the Credit Paragraph Boeing asked that we move the terminating action specified in paragraph (l)(3) of the proposed AD (in the NPRM) into the credit for previous actions specified in paragraph (m) of the proposed AD (in the NPRM) for clarification. Boeing stated that accomplishment of the repair or preventive modification, as specified in Boeing Message M–7200–02–1294, dated August 20, 2002, is a ‘‘previous action’’ similar to accomplishment of the repair or preventive modification specified in Boeing Alert Service Bulletin 737–53A1261, dated January 19, 2006. Boeing added that paragraph (l)(3) of the proposed AD (in the NPRM) stated that the repair or preventive modification done before the effective date of the AD terminates the repetitive inspection requirements of paragraph (g)(1) of the proposed AD (in the NPRM). Boeing also asked that we revise the proposed AD (in the NPRM) to state that accomplishment of the repair or preventive modification in accordance with Boeing Message M– 7200–02–1294, dated August 20, 2002, if performed before the effective date of the AD, would also terminate the preventive modification required by paragraph (k) of the proposed AD (in the NPRM). We agree to revise paragraph (l)(3) of this proposed AD to state that a repair or preventive modification done in accordance with Boeing Message M– 7200–02–1294, dated August 20, 2002, is acceptable for terminating both the inspections and the preventive modification requirements in paragraphs (g)(1) and (k) of this proposed AD respectively. We have changed paragraph (l)(3) of this proposed AD accordingly. We do not agree to move paragraph (l)(3) of the proposed AD (in the NPRM) into the credit for previous actions VerDate Sep<11>2014 15:04 Nov 10, 2016 Jkt 241001 specified in paragraph (m) of this proposed AD. Paragraph (m) of this proposed AD is intended to give credit for actions accomplished using previous revisions of service information for accomplishing corresponding actions prior to the effective date of the AD; it does not terminate any actions and does not address future actions. Request To Provide Credit for Certain Repairs Boeing asked that we change paragraph (m) of the proposed AD (in the NPRM) to provide credit for repairs that were accomplished before the effective date of the AD, in accordance with Boeing Alert Service Bulletin 737– 53A1261, dated January 19, 2006. Boeing stated that the repair procedures are the same as those in Boeing Alert Service Bulletin 737–53A1261, Revision 1, dated January 30, 2015 (as specified in paragraph (l)(2) of the proposed AD (in the NPRM)). We agree with the commenter for the reason provided. We have added a new paragraph (m)(3) to this proposed AD to give credit for repairs specified in paragraph (l)(2) of the this proposed AD that are accomplished before the effective date of this proposed AD. Request To Remove Repairs as Terminating Action Under Certain Conditions Boeing asked that we change paragraph (l)(4) of the proposed AD (in the NPRM) to remove repairs as acceptable terminating action. Boeing stated that paragraph (l)(4) of the proposed AD (in the NPRM) would provide a terminating action provision for the repetitive inspections required by paragraph (g)(2) of the proposed AD (in the NPRM) if a repair or preventive modification is accomplished that is different from the one provided in Boeing Alert Service Bulletin 737– 53A1261, Revision 1, dated January 30, 2015, provided it has been approved by the Manager, Los Angeles Aircraft Certification Office. Boeing added that there have been repairs performed in the past that involve trimming the production upper frame web near S–11 and replacing it with an identical replacement frame web without additional reinforcement similar to the preventive modification or repair. Boeing noted that the repair is structurally acceptable; however, it does not sufficiently reinforce the frame to provide terminating action for the inspections, and would require further service actions, including inspections and a preventive modification. Boeing added that the additional inspection PO 00000 Frm 00004 Fmt 4702 Sfmt 4702 79397 requirements should be specified in the AMOC approval, and noted that a preventive modification would not necessarily be required since prior approvals would not have taken the WFD requirements into account. We agree with the commenter for the reasons provided. All previously installed repairs or modifications installed in accordance with Boeing Alert Service Bulletin 737–53A1261, dated January 19, 2006, must be reevaluated or replaced to ensure that all WFD requirements are met. Therefore, we have removed paragraph (l)(4) of the proposed AD (in the NPRM) from this proposed AD. 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 NPRM. 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 accomplishing the actions specified in the service information described previously, except as discussed under ‘‘Difference Between this AD and the Service Information.’’ Refer to this service information for information on the procedures and compliance times. Difference Between This SNPRM and the Service Information Boeing Alert Service Bulletin 737– 53A1261, Revision 1, dated January 30, 2015, specifies to contact the manufacturer for certain repair instructions, but this proposed AD would require repair methods, modification deviations, and alteration deviations in one of the following ways: • In accordance with a method that we approve; or • Using data that meet the certification basis of the airplane, and that have been approved by the Boeing Commercial Airplanes Organization Designation Authorization (ODA) whom we have authorized to make those findings. Costs of Compliance We estimate that this proposed AD affects 391 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: E:\FR\FM\14NOP1.SGM 14NOP1 79398 Federal Register / Vol. 81, No. 219 / Monday, November 14, 2016 / Proposed Rules ESTIMATED COSTS Parts cost Cost per product Cost on U.S. operators Between 18 and 38 work-hours × $85 per hour, depending on airplane configuration = between $1,530 and $3,230 per inspection cycle. $0 Between $1,530 and $3,230 per inspection cycle. 213 work-hours × $85 per hour, $18,105 per inspection cycle ........ $0 256 work-hours × $85 per hour = $21,760 .......................................

New proposed modification. 1 We currently have no specific cost estimates associated with the parts necessary for the proposed modification. under the criteria of the Regulatory Flexibility Act. We have received no definitive data that would enable us to provide a cost estimate for the on-condition actions specified in this proposed AD. Lhorne on DSK30JT082PROD with PROPOSALS 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 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 VerDate Sep<11>2014 15:04 Nov 10, 2016 Jkt 241001 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 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 removing Airworthiness Directive (AD) 2008–13–12 R1, Amendment 39–15719 (73 FR 67383, November 14, 2008), and adding the following new AD. ■ The Boeing Company: Docket No. FAA– 2015–3984; Directorate Identifier 2015– NM–033–AD. (a) Comments Due Date We must receive comments by December 29, 2016. (b) Affected ADs This AD replaces AD 2008–13–12 R1, Amendment 39–15719 (73 FR 67383, November 14, 2008) (‘‘AD 2008–13–12 R1’’). (c) Applicability (1) This AD applies to The Boeing Company Model 737–100, –200, –200C, –300, –400, and –500 series airplanes, certificated in any category, as identified in Boeing Alert Service Bulletin 737–53A1261, Revision 1, dated January 30, 2015. (2) Installation of Supplemental Type Certificate (STC) ST01219SE (http:// rgl.faa.gov/Regulatory_and_Guidance_ Library/rgstc.nsf/0/BE866B732F6CF31086257 B9700692796?OpenDocument&Highlight=st0 1219se) 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 PO 00000 Frm 00005 Fmt 4702 Sfmt 4702 (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 53, Fuselage. (e) Unsafe Condition This AD was prompted by reports of additional fatigue cracking of the upperframe-to-side-frame splice of the fuselage, and one report of a severed frame due to susceptibility to widespread fatigue damage (WFD). We are issuing this AD to detect and correct fatigue cracking of the upper-frameto-side-frame splice of the fuselage, which could result in reduced structural integrity of the frame and adjacent lap joint, causing increased loading in the fuselage skin, which will accelerate skin crack growth and result in decompression of the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done.

SUPPLEMENTARY INFORMATION: [Docket No. FDA–2008–N–0622] I. Background Withdrawal of Two Proposed Rules In 1990, FDA began a process of periodically conducting comprehensive reviews of its regulation process, including reviewing the backlog of notices of proposed rulemakings that were never finalized. As FDA removed many proposed rules that had not been finalized, the Agency was able to clean out the backlog and implement a process of reviewing these proposed rules every 5 years. In the Federal Register of December 12, 2008 (73 FR 75625), FDA withdrew four proposed rules that were more than 5 years old that it did not intend to finalize. Recently, FDA has conducted a review of proposed rules that are more than 5 years old, and is announcing the withdrawal the following two proposed rules: DEPARTMENT OF HEALTH AND HUMAN SERVICES Food and Drug Administration AGENCY: Food and Drug Administration, HHS. ACTION: Notice of withdrawal. The Food and Drug Administration (FDA) is announcing the withdrawal of two proposed rules that published in the Federal Register more than 5 years ago. These proposed rules are no longer considered viable candidates for final action. FDA is taking this action because these proposed rules are out of date. DATES: The proposed rules are withdrawn on November 14, 2016. FOR FURTHER INFORMATION CONTACT: Lisa M. Helmanis, Regulations Policy and Management Staff, Office of the SUMMARY: Publication date and Docket No. Reason for withdrawal 1 ...................

Lhorne on DSK30JT082PROD with PROPOSALS Title of proposed rule Crabmeat; Amendment of Common or Usual Name Regulation. 4/23/1998, 94P–0043 .... FDA has reconsidered our position on this issue and deemed our concerns from 2001 outdated. We will continue to assess whether rulemaking in this area is necessary, and if so, we will proceed with a new proposed rule. This proposed rule is obsolete because FDA has created a new process that allows for routine updates to the seafood names without going through notice and comment rulemaking. See FDA’s Guide to Acceptable Market Names for Seafood Sold in Interstate Commerce. The withdrawal of these proposals identified in this document does not preclude the Agency from reinstituting rulemaking concerning the issues addressed in the proposals listed in the chart. Should we decide to undertake such rulemakings in the future, we will re-propose the actions and provide new opportunities for comment. Furthermore, this notice is only intended to address the specific actions identified in this document, and not any other pending proposals that the Agency has issued or is considering. The Agency notes that withdrawal of a proposal does not necessarily mean that the preamble statement of the proposal no longer reflects the current position of FDA on the matter addressed.

14 CFR Part 39

[Docket No. FAA-2015-3984; Directorate Identifier 2015-NM-033-AD]
RIN 2120-AA64


Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

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

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

SUMMARY: We are revising an earlier proposal to supersede Airworthiness 
Directive (AD) 2008-13-12 R1, for certain The Boeing Company Model 737-
100, -200, -200C, -300, -400, and -500 series airplanes. AD 2008-13-12 
R1 requires various repetitive inspections for cracking of the upper-
frame-to-side-frame splice of the fuselage, and other specified and 
corrective actions if necessary; and also provides for an optional 
preventive modification, which would terminate the repetitive 
inspections. This action revises the notice of proposed rulemaking 
(NPRM) by adding post-repair/post-modification inspections. We are 
proposing this SNPRM to detect and correct fatigue cracking of the 
upper-frame-to-side-frame splice of the fuselage, which could result in 
reduced structural integrity of the frame and adjacent lap joint, 
causing increased loading in the fuselage skin, which will accelerate 
skin crack growth and result in decompression 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 December 29, 2016.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

Discussion

    We issued an NPRM to amend 14 CFR part 39 to supersede AD 2008-13-
12 R1, Amendment 39-15719 (73 FR 67383, November 14, 2008) (``AD 2008-
13-12 R1''). AD 2008-13-12 R1 applied to certain The Boeing Company 
Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. AD 
2008-13-12 R1 requires various repetitive inspections for cracking of 
the upper-frame-to-side-frame splice of the fuselage, and other 
specified and corrective actions if necessary. AD 2008-13-12 R1 also 
provides for an optional preventive modification, which terminates the 
repetitive inspections. AD 2008-13-12 R1 resulted from a report that 
the upper frame of the fuselage was severed between stringers (S) S-13L 
and S-14L at station (STA) 747, and the adjacent frame at STA 767 had a 
1.3-inch-long crack at the same stringer location. The NPRM published 
in the Federal Register on October 9, 2015 (80 FR 61133) (``The 
NPRM''). The NPRM was prompted by reports of additional fatigue 
cracking of the upper-frame-to-side-frame splice of the fuselage, and 
one report of a severed frame. The NPRM proposed to add, for certain 
airplanes, an inspection to determine if the existing frame repair 
meets all specified requirements, and for certain other airplanes, a 
new modification of the upper-frame-to-side-frame splice, which would 
terminate the repetitive inspections. The NPRM also proposed to reduce 
certain inspection thresholds and repetitive intervals.

Actions Since Previous NPRM Was Issued

    Since we issued the NPRM, we have determined that it is necessary 
to require post-repair/post-modification inspections that were not 
included in the NPRM.

Related Service Information Under 1 CFR Part 51

    We reviewed Boeing Alert Service Bulletin 737-53A1261, Revision 1, 
dated January 30, 2015. The service information describes procedures 
for various repetitive inspections for cracking of the upper-frame-to-
side-frame splice of the fuselage, a preventive modification to prevent 
WFD, an inspection to determine if the existing frame repair meets all 
specified requirements, and corrective actions. This service 
information is reasonably available because the interested parties

[[Page 79396]]

have access to it through their normal course of business or by the 
means identified in the ADDRESSES section.

Comments

    We gave the public the opportunity to comment on the NPRM. The 
following presents the comments received on the NPRM and the FAA's 
response to each comment. One commenter supported the actions specified 
in the NPRM.

Request To Require Post-Repair/Post-Modification Inspections

    Boeing asked that we change paragraph (j) of the proposed AD (in 
the NPRM) to require the post-repair/post-modification inspections that 
are not required in that paragraph. Boeing stated that the WFD 
evaluation of the frame repair/modification specified in Boeing Alert 
Service Bulletin 737-53A1261, Revision 1, dated January 30, 2015, 
indicated the need for reduced repetitive inspection intervals from 
those provided in Boeing Damage Tolerance Inspection Data Service 
Bulletin 737-00-1006, dated March 12, 2010. Boeing added that since the 
inspections specified in Boeing Service Bulletin 737-00-1006, dated 
March 12, 2010, are not to be used for the post-repair/post-
modification inspections required by 14 CFR 121.1109(c)(2) or 
129.109(c)(2), they should be required by paragraph (j) of the proposed 
AD.
    We agree with the commenter for the reasons provided. We have 
changed paragraph (j) of this SNPRM to require that post-repair/post-
modification inspections be done in accordance with the Accomplishment 
Instructions of Boeing Alert Service Bulletin 737-53A1261, Revision 1, 
dated January 30, 2015.

Effect of Winglets on Accomplishment of the Proposed Actions

    Aviation Partners Boeing stated that accomplishing the Supplemental 
Type Certificate (STC) ST01219SE does not affect the actions specified 
in the NPRM.
    We agree with the commenter. We have changed paragraph (c) of this 
proposed AD to state that installation of STC ST01219SE does not affect 
the ability to accomplish the actions required by this final rule. 
Therefore, for airplanes on which STC ST01219SE is installed, a 
``change in product'' alternative methods of compliance (AMOC) approval 
request is not necessary to comply with the requirements of 14 CFR 
39.17.

Request To Clarify That the NPRM Addresses WFD

    Boeing asked that we update the language in ``Actions Since AD 
2008-13-12 R1, Amendment 39-15719 (73 FR 67383, November 14, 2008) Was 
Issued'' section of the NPRM to clarify that this action is intended to 
address WFD by supporting the airplane's limit of validity (LOV). 
Boeing noted that a recently issued WFD-related AD action used 
different language regarding WFD. Boeing stated that Boeing Alert 
Service Bulletin 737-53A1261, Revision 1, dated January 30, 2015, was 
released in support of the requirements of 14 CFR 26.21(b) and (c) and 
provides additional service action required to support LOV.
    We agree to provide clarification. The NPRM addressed WFD in 
several locations in the preamble. To clarify, this action is intended 
to address WFD by supporting the airplane's LOV, as stated by Boeing. 
However, we have not updated the language in that section of the NPRM 
because that section of the NPRM is not carried over to this SNPRM. 
Therefore, no change to this SNPRM is necessary in this regard.

Request To Clarify Certain Procedures in the Related Service 
Information Section

    Boeing asked that we change the ``Related Service Information under 
1 CFR part 51'' section in the NPRM to clarify the description of the 
modification procedures in the service information. Boeing asked that 
the proposed language ``. . . a new preventive modification, which 
would eliminate the need for the repetitive inspections'' be changed to 
``. . . a preventive modification to prevent the WFD.'' Boeing stated 
that Boeing Alert Service Bulletin 737-53A1261, Revision 1, dated 
January 30, 2015, retains all inspections specified in Boeing Alert 
Service Bulletin 737-53A1261, dated January 19, 2006, and mandates the 
previously optional preventive modification to mitigate the WFD 
concern.
    We agree with the commenter for the reasons provided. We have 
clarified the ``Related Service Information under 1 CFR part 51'' 
section of this SNPRM accordingly.

Request To Clarify Reason for Supersedure

    Boeing asked that we clarify in the SUMMARY section of the NPRM the 
events that prompted the proposed supersedure of AD 2008-13-12 R1. 
Boeing stated that instead of two reports of severed frames, as 
specified in the NPRM, there was just one report of a severed frame.
    We agree to provide clarification. We agree that the commenter's 
statement is accurate. However, we have removed details relating to the 
NPRM from the SUMMARY section of this SNPRM; therefore, no change is 
necessary to this SNPRM in this regard.

Request To Clarify Provisions Related to Repetitive Actions

    Boeing asked that we clarify paragraph (g)(1)(ii) of the proposed 
AD (in the NPRM) to state that the actions are to be repeated until the 
preventive modification in paragraph (k) or the terminating action in 
paragraph (l) of the proposed AD has been accomplished. Boeing added 
that this change is consistent with the provisions of Boeing Alert 
Service Bulletin 737-53A1261, Revision 1, dated January 30, 2015, and 
the requirements of AD 2008-13-12 R1.
    We agree with the commenter for the reasons provided. We have 
clarified paragraph (g)(1)(ii) of this proposed AD accordingly.

Request To Clarify Inspection Locations

    Boeing asked that we change paragraph (g)(2)(i) of the proposed AD 
(in the NPRM) to clarify that the inspections are for ``existing frame 
repairs,'' instead of ``frames.'' Boeing requested that we change 
``frame'' to ``frame repairs,'' and ``tied frames'' to ``existing frame 
repairs.''
    We agree with the commenter. We have revised paragraph (g)(2)(i) of 
this proposed AD accordingly.

Request To Revise Inspection Type

    Boeing asked that we revise paragraphs (k) and (l) of the proposed 
AD (in the NPRM) by changing ``detailed and HFEC inspections'' to just 
``HFEC inspections.'' Boeing stated that detailed inspections are not 
specified during accomplishment of the preventive modification in 
Boeing Alert Service Bulletin 737-53A1261, Revision 1, dated January 
30, 2015.
    We agree with the commenter for the reason provided. We have 
removed ``detailed'' inspections from paragraphs (k) and (l) of this 
proposed AD.

Request To Change Certain Language in Paragraph (l)(2) of the Proposed 
AD

    Boeing asked that we change paragraph (l)(2) of the proposed AD (in 
the NPRM), which stated that the repair would terminate the repetitive 
inspections required by paragraph (g)(1) of this AD. Boeing requested 
that the proposed AD instead state that the repair would terminate not 
only the repetitive inspections, but also the preventive modification 
required by

[[Page 79397]]

paragraph (k) of the proposed AD. Boeing added that Boeing Alert 
Service Bulletin 737-53A1261, Revision 1, dated January 30, 2015, 
provides a terminating action provision for the repetitive inspections 
and the preventive modification under the repair. Boeing stated that 
accomplishment of the repair removes the WFD, and therefore the 
preventive modification is not required for repaired frames.
    We agree with the commenter for the reasons provided. We have 
clarified the language in paragraph (l)(2) of this proposed AD 
accordingly.

Request To Move Terminating Action in Paragraph (l)(3) of the Proposed 
AD to the Credit Paragraph

    Boeing asked that we move the terminating action specified in 
paragraph (l)(3) of the proposed AD (in the NPRM) into the credit for 
previous actions specified in paragraph (m) of the proposed AD (in the 
NPRM) for clarification. Boeing stated that accomplishment of the 
repair or preventive modification, as specified in Boeing Message M-
7200-02-1294, dated August 20, 2002, is a ``previous action'' similar 
to accomplishment of the repair or preventive modification specified in 
Boeing Alert Service Bulletin 737-53A1261, dated January 19, 2006. 
Boeing added that paragraph (l)(3) of the proposed AD (in the NPRM) 
stated that the repair or preventive modification done before the 
effective date of the AD terminates the repetitive inspection 
requirements of paragraph (g)(1) of the proposed AD (in the NPRM). 
Boeing also asked that we revise the proposed AD (in the NPRM) to state 
that accomplishment of the repair or preventive modification in 
accordance with Boeing Message M-7200-02-1294, dated August 20, 2002, 
if performed before the effective date of the AD, would also terminate 
the preventive modification required by paragraph (k) of the proposed 
AD (in the NPRM).
    We agree to revise paragraph (l)(3) of this proposed AD to state 
that a repair or preventive modification done in accordance with Boeing 
Message M-7200-02-1294, dated August 20, 2002, is acceptable for 
terminating both the inspections and the preventive modification 
requirements in paragraphs (g)(1) and (k) of this proposed AD 
respectively. We have changed paragraph (l)(3) of this proposed AD 
accordingly.
    We do not agree to move paragraph (l)(3) of the proposed AD (in the 
NPRM) into the credit for previous actions specified in paragraph (m) 
of this proposed AD. Paragraph (m) of this proposed AD is intended to 
give credit for actions accomplished using previous revisions of 
service information for accomplishing corresponding actions prior to 
the effective date of the AD; it does not terminate any actions and 
does not address future actions.

Request To Provide Credit for Certain Repairs

    Boeing asked that we change paragraph (m) of the proposed AD (in 
the NPRM) to provide credit for repairs that were accomplished before 
the effective date of the AD, in accordance with Boeing Alert Service 
Bulletin 737-53A1261, dated January 19, 2006. Boeing stated that the 
repair procedures are the same as those in Boeing Alert Service 
Bulletin 737-53A1261, Revision 1, dated January 30, 2015 (as specified 
in paragraph (l)(2) of the proposed AD (in the NPRM)).
    We agree with the commenter for the reason provided. We have added 
a new paragraph (m)(3) to this proposed AD to give credit for repairs 
specified in paragraph (l)(2) of the this proposed AD that are 
accomplished before the effective date of this proposed AD.

Request To Remove Repairs as Terminating Action Under Certain 
Conditions

    Boeing asked that we change paragraph (l)(4) of the proposed AD (in 
the NPRM) to remove repairs as acceptable terminating action. Boeing 
stated that paragraph (l)(4) of the proposed AD (in the NPRM) would 
provide a terminating action provision for the repetitive inspections 
required by paragraph (g)(2) of the proposed AD (in the NPRM) if a 
repair or preventive modification is accomplished that is different 
from the one provided in Boeing Alert Service Bulletin 737-53A1261, 
Revision 1, dated January 30, 2015, provided it has been approved by 
the Manager, Los Angeles Aircraft Certification Office. Boeing added 
that there have been repairs performed in the past that involve 
trimming the production upper frame web near S-11 and replacing it with 
an identical replacement frame web without additional reinforcement 
similar to the preventive modification or repair. Boeing noted that the 
repair is structurally acceptable; however, it does not sufficiently 
reinforce the frame to provide terminating action for the inspections, 
and would require further service actions, including inspections and a 
preventive modification. Boeing added that the additional inspection 
requirements should be specified in the AMOC approval, and noted that a 
preventive modification would not necessarily be required since prior 
approvals would not have taken the WFD requirements into account.
    We agree with the commenter for the reasons provided. All 
previously installed repairs or modifications installed in accordance 
with Boeing Alert Service Bulletin 737-53A1261, dated January 19, 2006, 
must be reevaluated or replaced to ensure that all WFD requirements are 
met. Therefore, we have removed paragraph (l)(4) of the proposed AD (in 
the NPRM) from this proposed AD.

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 NPRM. 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 accomplishing the actions specified in the 
service information described previously, except as discussed under 
``Difference Between this AD and the Service Information.'' Refer to 
this service information for information on the procedures and 
compliance times.

Difference Between This SNPRM and the Service Information

    Boeing Alert Service Bulletin 737-53A1261, Revision 1, dated 
January 30, 2015, specifies to contact the manufacturer for certain 
repair instructions, but this proposed AD would require repair methods, 
modification deviations, and alteration deviations in one of the 
following ways:
     In accordance with a method that we approve; or
     Using data that meet the certification basis of the 
airplane, and that have been approved by the Boeing Commercial 
Airplanes Organization Designation Authorization (ODA) whom we have 
authorized to make those findings.

Costs of Compliance

    We estimate that this proposed AD affects 391 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

    We have received no definitive data that would enable us to provide 
a cost estimate for the on-condition actions specified in this proposed 
AD.

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 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 removing Airworthiness Directive (AD) 
2008-13-12 R1, Amendment 39-15719 (73 FR 67383, November 14, 2008), and 
adding the following new AD.

The Boeing Company: Docket No. FAA-2015-3984; Directorate Identifier 
2015-NM-033-AD.

(a) Comments Due Date

    We must receive comments by December 29, 2016.

(b) Affected ADs

    This AD replaces AD 2008-13-12 R1, Amendment 39-15719 (73 FR 
67383, November 14, 2008) (``AD 2008-13-12 R1'').

(c) Applicability

    (1) This AD applies to The Boeing Company Model 737-100, -200, -
200C, -300, -400, and -500 series airplanes, certificated in any 
category, as identified in Boeing Alert Service Bulletin 737-
53A1261, Revision 1, dated January 30, 2015.
    (2) Installation of Supplemental Type Certificate (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.

(d) Subject

    Air Transport Association (ATA) of America Code 53, Fuselage.

(e) Unsafe Condition

    This AD was prompted by reports of additional fatigue cracking 
of the upper-frame-to-side-frame splice of the fuselage, and one 
report of a severed frame due to susceptibility to widespread 
fatigue damage (WFD). We are issuing this AD to detect and correct 
fatigue cracking of the upper-frame-to-side-frame splice of the 
fuselage, which could result in reduced structural integrity of the 
frame and adjacent lap joint, causing increased loading in the 
fuselage skin, which will accelerate skin crack growth and result in 
decompression of the airplane.

(f) Compliance

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

(g) Repetitive Inspections and Corrective Actions for Certain Airplanes

    (1) For Groups 1 through 3, Configurations 1, 3, 4, and 5
