ACTION: Final rule. AGENCY: We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 747–100, 747– 100B, 747–100B SUD, 747–200B, 747– 200C, 747–200F, 747–300, 747–400, 747–400D, 747–400F, 747SR, and 747SP series airplanes. This AD was prompted by a report of incidents involving fatigue cracking in transport category airplanes that are approaching or have exceeded their design service objective and a structural reevaluation by the manufacturer that identified additional structural elements that qualify as structural significant items (SSIs). This AD requires revising the maintenance or inspection program, as applicable, to include inspections that will give no less than the required damage tolerance rating (DTR) for certain SSI, performing repetitive inspections to detect cracks of all SSIs, and repairing cracked structures if necessary. Additionally, this AD requires all cracks involving an SSI or related structure in close vicinity to the SSI to be reported to Boeing. We are issuing this AD to address the unsafe condition on these products. DATES: This AD is effective March 30, 2018. daltland on DSKBBV9HB2PROD with RULES SUMMARY: VerDate Sep<11>2014 16:46 Feb 22, 2018 Jkt 244001 You may examine the AD docket on the internet at https:// www.regulations.gov by searching for and locating Docket No. FAA–2016– 9067; or in person at Docket Operations between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all The Boeing Company Model 747–100, 747–100B, 747–100B SUD, 747–200B, 747–200C, 747–200F, 747– 300, 747–400, 747–400D, 747–400F, 747SR, and 747SP series airplanes. The NPRM published in the Federal Register on September 8, 2016 (81 FR 62031). The NPRM was prompted by a report of incidents involving fatigue cracking in transport category airplanes that are approaching or have exceeded their design service objective and a structural reevaluation by the manufacturer that identified additional structural elements that qualify as SSIs. PO 00000 Frm 00025 Fmt 4700 Sfmt 4700 7975 The NPRM proposed to require revising the maintenance or inspection program, as applicable, to include inspections that will give no less than the required DTR for certain SSIs, and repairing any cracked structure. The NPRM proposed to require inspections to detect cracks of all SSI structure, and repair if necessary. We issued a supplemental notice of proposed rulemaking (SNPRM) to amend 14 CFR part 39 by adding an AD that would apply to all The Boeing Company Model 747–100, 747–100B, 747–100B SUD, 747–200B, 747–200C, 747–200F, 747–300, 747–400, 747– 400D, 747–400F, 747SR, and 747SP series airplanes. The SNPRM published in the Federal Register on November 9, 2017 (82 FR 52015). The SNPRM revised the NPRM by proposing to require reporting in order to ensure the continuing structural airworthiness of The Boeing Company Model 747–100, 747–100B, 747–100B SUD, 747–200B, 747–200C, 747–200F, 747–300, 747– 400, 747–400D, 747–400F, 747SR, and 747SP series airplanes with a high number of flight cycles. All cracks involving an SSI or related structure in close vicinity to the SSI must be reported to Boeing in order to evaluate the effectiveness of the supplemental structural inspections. We are issuing this AD to ensure the continued structural integrity of all The Boeing Company Model 747–100, 747– 100B, 747–100B SUD, 747–200B, 747– 200C, 747–200F, 747–300, 747–400, 747–400D, 747–400F, 747SR, and 747SP series airplanes. Comments We gave the public the opportunity to participate in developing this final rule. We have considered the comments received. The Boeing Company, British Airways, and United Airlines supported the SNPRM. Conclusion We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting this final rule as proposed, except for minor editorial changes. We have determined that these minor changes: • Are consistent with the intent that was proposed in the SNPRM for addressing the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the SNPRM. Related Service Information Under 1 CFR Part 51 We reviewed Boeing Document D6– 35022, ‘‘Supplemental Structural Inspection Document for Model 747 E:\FR\FM\23FER1.SGM 23FER1 7976 Federal Register / Vol. 83, No. 37 / Friday, February 23, 2018 / Rules and Regulations Airplanes,’’ Revision H, dated September 2013. This service information describes procedures for inspections to detect cracks of all structures identified as SSIs, and includes six new SSIs since the last revision. We also reviewed Boeing Document D6–35022–1, ‘‘747–400 LCF Supplemental Structural Inspection Document—Appendix A,’’ dated November 2015. This service information describes procedures for inspections of the wings, fuselage, and empennage SSIs for Model 747–400 LCF airplanes. This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section. Costs of Compliance We estimate that this AD affects 118 airplanes of U.S. registry. We estimate the following costs to comply with this AD: ESTIMATED COSTS Action Labor cost Revision of maintenance or inspection program. 1 work-hour × $85 per hour = $85 ................. We have not specified cost estimates for the inspection and repair specified in this AD. Compliance with this AD constitutes a method of compliance with the FAA aging airplane safety final rule (AASFR) (70 FR 5518, February 2, 2005) for certain baseline structure of Model 747–100, 747–100B, 747–100B SUD, 747–200B, 747–200C, 747–200F, 747–300, 747–400, 747–400D, 747– 400F, 747SR, and 747SP series airplanes. The AASFR requires certain operators to incorporate damage Cost per product Parts cost tolerance inspections into their maintenance inspection programs. These requirements are described in 14 CFR 121.1109(c)(1) and 14 CFR 129.109(b)(1). Accomplishment of the actions specified in this AD will meet the requirements of these regulations for certain baseline structure. The costs for accomplishing the inspection and repair portions of this AD were accounted for in the regulatory evaluation of the AASFR for airplanes affected by that rule. For airplanes not affected by the $0 $85 Cost on U.S. operators $10,030 AASFR, we have received no definitive data that would enable us to provide cost estimates for the inspection or repair portions of this AD. We estimate the following costs to do any necessary reporting that would be required based on the results of the inspections in the maintenance inspection program. We have no way of determining the number of aircraft that might need this action: ON-CONDITION COSTS Action Labor cost Reporting ............................................................ 1 work-hour × $85 per hour = $85 .................... daltland on DSKBBV9HB2PROD with RULES 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 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 control number for the collection of information required by this AD is 2120–0056. The paperwork cost associated with this AD has been detailed in the Costs of Compliance section of this document and includes time for reviewing instructions, as well as completing and reviewing the collection of information. Therefore, all reporting associated with this AD is 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. VerDate Sep<11>2014 16:46 Feb 22, 2018 Jkt 244001 Parts cost 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. This AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance PO 00000 Frm 00026 Fmt 4700 Sfmt 4700 Cost per product $0 $85 per inspection cycle. of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to transport category airplanes and associated appliances to the Director of the System Oversight Division. 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 E:\FR\FM\23FER1.SGM 23FER1 Federal Register / Vol. 83, No. 37 / Friday, February 23, 2018 / Rules and Regulations (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.

SUPPLEMENTARY INFORMATION: I. Interim Final Rule Section 1a of the Commodity Exchange Act (‘‘CEA’’) 2 sets forth defined terms referenced throughout the statute. These terms are alphabetized and numbered, currently beginning with ‘‘(1) Alternative Trading System’’ and ending with ‘‘(51) Trading Facility.’’ Whenever defined terms are added by Congress, the new term is placed in the proper location in the alphabetic order and the entire list is renumbered. The alphabetized list makes it relatively easy for an individual completely unfamiliar with the CEA to find a particular term referenced in the statute. Commission regulation § 1.3 similarly sets forth many definitions referenced throughout the Commission’s 1 17 CFR 145.9. Commission regulations referred to herein are found at 17 CFR chapter I. 2 7 U.S.C. 1 et seq. PO 00000 Frm 00029 Fmt 4700 Sfmt 4700 7979 regulations.3 Starting in 1938, the defined terms have been identified with an alphabetic designation consistent with the structure set forth in the Code of Federal Regulations (‘‘CFR’’).4 The CFR identifies regulations by ‘‘title,’’ divided into ‘‘chapters,’’ further subdivided into ‘‘parts,’’ and further subdivided into ‘‘sections’’ and ‘‘paragraphs.’’ Thus, the definitions in § 1.3 are set forth in Title 17 (Commodity and Securities Exchanges), Chapter I (Commodity Futures Trading Commission), Part 1 (General Regulations Under the Commodity Exchange Act), § 1.3 (Definitions). Each defined term then was originally set forth in paragraphs in alphabetical order, each with an alphabetic designation, starting with ‘‘(a) Board of Trade’’ and continuing through ‘‘(u) Person.’’ 5 Over decades, numerous definitions have been added by simply adding more paragraphs at the end (rather than in alphabetical order) with an ever-growing list of alphabetic designations, starting with ‘‘(aa)’’ after reaching ‘‘(z)’’ and then ‘‘(aaa)’’ after reaching ‘‘(zz).’’ Moreover, certain definitions have been removed, leaving certain paragraphs blank and cited as ‘‘reserved.’’ As of today, the list of definitions in § 1.3 concludes with ‘‘(ssss) Trading Facility.’’ The result of this progression has been that, absent a strong familiarity with the Commission’s regulations, it can prove difficult to quickly locate defined terms within § 1.3, either directly or as referred to by another regulation, or even to know if certain terms have been defined. Accordingly, the Commission has determined to amend § 1.3 to replace the sub-paragraphs currently identified with an alphabetic designation for each defined term with a simple alphabetized list, as is recommended by the Office of the Federal Register.6 Moving forward, any new defined terms in § 1.3 may be inserted in alphabetical order, rather than appended to the end. The Commission also has determined to amend all cross references to § 1.3— both within § 1.3 and within all other Commission regulations—to refer to the defined term set forth in the revised 3 17 CFR 1.3. The Commission’s regulations are found in Title 17 of the Code of Federal Regulations, 17 CFR chapter I. 4 See 17 CFR 1.3 (1938 ed.). 5 Id. 6 See Document Drafting Handbook, Office of the Federal Register, National Archives and Records Administration, 2–31 (Revision 5, Oct. 2, 2017), stating, ‘‘[i]n sections or paragraphs containing only definitions, we recommend that you do not use paragraph designations if you list the terms in alphabetical order. Begin the definition paragraph with the term that you are defining.’’ E:\FR\FM\23FER1.SGM 23FER1

Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for all The 
Boeing Company Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-
200C, 747-200F, 747-300, 747-400, 747-400D, 747-400F, 747SR, and 747SP 
series airplanes. This AD was prompted by a report of incidents 
involving fatigue cracking in transport category airplanes that are 
approaching or have exceeded their design service objective and a 
structural reevaluation by the manufacturer that identified additional 
structural elements that qualify as structural significant items 
(SSIs). This AD requires revising the maintenance or inspection 
program, as applicable, to include inspections that will give no less 
than the required damage tolerance rating (DTR) for certain SSI, 
performing repetitive inspections to detect cracks of all SSIs, and 
repairing cracked structures if necessary. Additionally, this AD 
requires all cracks involving an SSI or related structure in close 
vicinity to the SSI to be reported to Boeing. We are issuing this AD to 
address the unsafe condition on these products.

DATES: This AD is effective March 30, 2018.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of March 30, 
2018.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to all The Boeing Company 
Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-200F, 
747-300, 747-400, 747-400D, 747-400F, 747SR, and 747SP series 
airplanes. The NPRM published in the Federal Register on September 8, 
2016 (81 FR 62031). The NPRM was prompted by a report of incidents 
involving fatigue cracking in transport category airplanes that are 
approaching or have exceeded their design service objective and a 
structural reevaluation by the manufacturer that identified additional 
structural elements that qualify as SSIs. The NPRM proposed to require 
revising the maintenance or inspection program, as applicable, to 
include inspections that will give no less than the required DTR for 
certain SSIs, and repairing any cracked structure. The NPRM proposed to 
require inspections to detect cracks of all SSI structure, and repair 
if necessary.
    We issued a supplemental notice of proposed rulemaking (SNPRM) to 
amend 14 CFR part 39 by adding an AD that would apply to all The Boeing 
Company Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-
200F, 747-300, 747-400, 747-400D, 747-400F, 747SR, and 747SP series 
airplanes. The SNPRM published in the Federal Register on November 9, 
2017 (82 FR 52015). The SNPRM revised the NPRM by proposing to require 
reporting in order to ensure the continuing structural airworthiness of 
The Boeing Company Model 747-100, 747-100B, 747-100B SUD, 747-200B, 
747-200C, 747-200F, 747-300, 747-400, 747-400D, 747-400F, 747SR, and 
747SP series airplanes with a high number of flight cycles. All cracks 
involving an SSI or related structure in close vicinity to the SSI must 
be reported to Boeing in order to evaluate the effectiveness of the 
supplemental structural inspections.
    We are issuing this AD to ensure the continued structural integrity 
of all The Boeing Company Model 747-100, 747-100B, 747-100B SUD, 747-
200B, 747-200C, 747-200F, 747-300, 747-400, 747-400D, 747-400F, 747SR, 
and 747SP series airplanes.

Comments

    We gave the public the opportunity to participate in developing 
this final rule. We have considered the comments received. The Boeing 
Company, British Airways, and United Airlines supported the SNPRM.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
this final rule as proposed, except for minor editorial changes. We 
have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
SNPRM for addressing the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the SNPRM.

Related Service Information Under 1 CFR Part 51

    We reviewed Boeing Document D6-35022, ``Supplemental Structural 
Inspection Document for Model 747

[[Page 7976]]

Airplanes,'' Revision H, dated September 2013. This service information 
describes procedures for inspections to detect cracks of all structures 
identified as SSIs, and includes six new SSIs since the last revision.
    We also reviewed Boeing Document D6-35022-1, ``747-400 LCF 
Supplemental Structural Inspection Document--Appendix A,'' dated 
November 2015. This service information describes procedures for 
inspections of the wings, fuselage, and empennage SSIs for Model 747-
400 LCF airplanes.
    This service information is reasonably available because the 
interested parties have access to it through their normal course of 
business or by the means identified in the ADDRESSES section.

Costs of Compliance

    We estimate that this AD affects 118 airplanes of U.S. registry. We 
estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                     Cost per      Cost on U.S.
                Action                         Labor cost           Parts cost        product        operators

 program.                                hour = $85.
----------------------------------------------------------------------------------------------------------------

    We have not specified cost estimates for the inspection and repair 
specified in this AD. Compliance with this AD constitutes a method of 
compliance with the FAA aging airplane safety final rule (AASFR) (70 FR 
5518, February 2, 2005) for certain baseline structure of Model 747-
100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-200F, 747-300, 
747-400, 747-400D, 747-400F, 747SR, and 747SP series airplanes. The 
AASFR requires certain operators to incorporate damage tolerance 
inspections into their maintenance inspection programs. These 
requirements are described in 14 CFR 121.1109(c)(1) and 14 CFR 
129.109(b)(1). Accomplishment of the actions specified in this AD will 
meet the requirements of these regulations for certain baseline 
structure. The costs for accomplishing the inspection and repair 
portions of this AD were accounted for in the regulatory evaluation of 
the AASFR for airplanes affected by that rule. For airplanes not 
affected by the AASFR, we have received no definitive data that would 
enable us to provide cost estimates for the inspection or repair 
portions of this AD.
    We estimate the following costs to do any necessary reporting that 
would be required based on the results of the inspections in the 
maintenance inspection program. We have no way of determining the 
number of aircraft that might need this action:

                                               On-Condition Costs
----------------------------------------------------------------------------------------------------------------
              Action                     Labor cost         Parts cost               Cost per product
----------------------------------------------------------------------------------------------------------------
Reporting.........................  1 work-hour x $85                 $0  $85 per inspection cycle.
                                     per hour = $85.

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 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 control 
number for the collection of information required by this AD is 2120-
0056. The paperwork cost associated with this AD has been detailed in 
the Costs of Compliance section of this document and includes time for 
reviewing instructions, as well as completing and reviewing the 
collection of information. Therefore, all reporting associated with 
this AD is 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.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to transport category airplanes and 
associated appliances to the Director of the System Oversight Division.

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

[[Page 7977]]

    (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.

using an FAA-approved method.

(l) Compliance Time Clarification

    For compliance times identified in paragraphs (i) and (j) of 
this AD that specify total flight cycles and total flight hours, and 
the SSI is a removable structural component, those compliance times 
must be measured on the SSI since its first installation on any 
airplane, regardless of what the airframe as a whole has 
accumulated. If the total flight cycles and total flight hours on 
the SSI are not available or cannot be determined, use the airframe 
total flight cycles and total flight hours for the compliance times 
identified in paragraphs (i) and (j) of this AD.

(m) No Alternative Inspections and Inspection Intervals

    After accomplishing the revision required by paragraph (h) of 
this AD, no alternative inspections or inspection intervals may be 
used unless the alternative inspection or inspection interval is 
approved as an alternative method of compliance (AMOC) in accordance 
with the procedures specified in paragraph (p) of this AD.

(n) Terminating Action for AD 2004-07-22 R1

    Accomplishing the revision required by paragraph (h) of this AD 
and all of the initial inspections required by paragraph (i) or (j) 
of this AD, as applicable, terminates all requirements of AD 2004-
07-22 R1.
