[FR Doc. 2016–03217 Filed 2–17–16; 8:45 am] BILLING CODE 4910–13–P DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2015–2460; Directorate Identifier 2014–NM–163–AD; Amendment 39–18396; AD 2016–04–02] RIN 2120–AA64 Airworthiness Directives; The Boeing Company Airplanes Federal Aviation Administration (FAA), DOT. ACTION: Final rule. AGENCY: We are superseding Airworthiness Directive (AD) 2010–26– 10, which applied to certain The Boeing Company Model 747–200C, –200F, –400, –400D, and –400F series airplanes. AD 2010–26–10 required repetitive inspections for cracking of the lap joints, modification of certain lap joints, and certain post-repair inspections of the lap joints. This new AD adds new repetitive postmodification inspections for cracking in the lap joints, and repair if necessary. This AD was prompted by an evaluation by the design approval holder (DAH) which indicated that certain lap joints are subject to widespread fatigue damage (WFD). We are issuing this AD to detect and correct fatigue cracking in certain lap joints, which could result in rapid depressurization and consequent reduced structural integrity of the airplane. SUMMARY: This AD is effective March 24, 2016. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of March 24, 2016.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2010–26–10, Amendment 39–16549 (75 FR 81427, December 28, 2010). AD 2010–26–10 applied to certain The Boeing Company Model 747–200C, –200F, –400, –400D, and –400F series airplanes. The NPRM published in the Federal Register on July 9, 2015 (80 FR 39394). The NPRM was prompted by an evaluation by the DAH that indicated that certain lap joints are subject to WFD. The NPRM proposed to continue to require repetitive inspections for cracking of the lap joints, modification of certain lap joints, and certain post-repair inspections of the lap joints. The NPRM also proposed to require new repetitive post-modification inspections for cracking in the lap joints, and repair if necessary. We are issuing this AD to detect and correct fatigue cracking in certain lap joints, which could result in rapid depressurization and consequent reduced structural integrity of the airplane. Comments We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the NPRM (80 FR 39394, July 9, 2015) and the FAA’s response to each comment. United Airlines concurred with the NPRM. Request To Correct Typographical Error Boeing asked that we correct the reference in the ‘‘Related Service Information under 1 CFR part 51’’ from ‘‘. . . sections 41, 42, and 43’’ to ‘‘. . . sections 41, 42, and 46.’’ Boeing stated that section 43 should be section 46, and noted that this is a typographical error. We agree with the commenter’s request for the reason provided. We have corrected this typographical error in ‘‘Related Service Information under 1 CFR part 51’’ accordingly. Request To Clarify Certain Requirements Boeing asked that we clarify paragraph (i)(1) of the proposed AD (80 FR 39394, July 9, 2015) by including ‘‘per Table 7’’ in that paragraph. Boeing also asked that we clarify paragraph (i)(3) of the proposed AD by including ‘‘per Table 10’’ in that paragraph. We agree that clarification is necessary but we do not agree to change paragraphs (i)(1) and (i)(3) of this AD. Paragraph (i) of this AD specifies doing the applicable inspections in paragraphs (i)(1), (i)(2), or (i)(3) of this AD, in accordance with the Accomplishment Instructions of the referenced service information; and repeating the 8141 applicable inspections at the applicable times specified in Tables 7, 8, 9, and 10 of paragraph 1.E., ‘‘Compliance,’’ of Boeing Alert Service Bulletin 747– 53A2499, Revision 3, dated July 15, 2014. In each of these tables the applicable groups are identified and match the groups identified in paragraphs (i)(1), (i)(2), and (i)(3) of this AD. We refer to the tables in paragraph 1.E., ‘‘Compliance,’’ of service information for the applicable compliance times and not for how to accomplish the required actions. Therefore, we have not changed this AD in this regard. Conclusion We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting this AD as proposed, with minor editorial changes. We have determined that these minor changes: • Are consistent with the intent that was proposed in the NPRM (80 FR 39394, July 9, 2015) for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM (80 FR 39394, July 9, 2015). Related Service Information Under 1 CFR Part 51 We reviewed Boeing Alert Service Bulletin 747–53A2499, Revision 3, dated July 15, 2014. The service information describes procedures for body skin lap joint inspections and modifications in sections 41, 42, and 46. 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 120 airplanes of U.S. registry. We estimate the following costs to comply with this AD: ESTIMATED COSTS wgreen on DSK2VPTVN1PROD with RULES Action Labor cost Pre-modification inspections [retained action from AD 2010–26–10, Amendment 39–16549 (75 FR 81427, December 28, 2010)].

E:\FR\FM\18FER1.SGM 18FER1 8142 Federal Register / Vol. 81, No. 32 / Thursday, February 18, 2016 / Rules and Regulations We have received no definitive data that would enable us to provide a cost estimate for the on-condition actions specified in this AD. PART 39—AIRWORTHINESS DIRECTIVES 1. The authority citation for part 39 continues to read as follows: ■ 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 have determined that 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. wgreen on DSK2VPTVN1PROD with RULES List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.

Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are superseding Airworthiness Directive (AD) 2010-26-10, 
which applied to certain The Boeing Company Model 747-200C, -200F, -
400, -400D, and -400F series airplanes. AD 2010-26-10 required 
repetitive inspections for cracking of the lap joints, modification of 
certain lap joints, and certain post-repair inspections of the lap 
joints. This new AD adds new repetitive post-modification inspections 
for cracking in the lap joints, and repair if necessary. This AD was 
prompted by an evaluation by the design approval holder (DAH) which 
indicated that certain lap joints are subject to widespread fatigue 
damage (WFD). We are issuing this AD to detect and correct fatigue 
cracking in certain lap joints, which could result in rapid 
depressurization and consequent reduced structural integrity of the 
airplane.

DATES: This AD is effective March 24, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of March 24, 
2016.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2010-26-10, Amendment 39-16549 (75 FR 81427, 
December 28, 2010). AD 2010-26-10 applied to certain The Boeing Company 
Model 747-200C, -200F, -400, -400D, and -400F series airplanes. The 
NPRM published in the Federal Register on July 9, 2015 (80 FR 39394). 
The NPRM was prompted by an evaluation by the DAH that indicated that 
certain lap joints are subject to WFD. The NPRM proposed to continue to 
require repetitive inspections for cracking of the lap joints, 
modification of certain lap joints, and certain post-repair inspections 
of the lap joints. The NPRM also proposed to require new repetitive 
post-modification inspections for cracking in the lap joints, and 
repair if necessary. We are issuing this AD to detect and correct 
fatigue cracking in certain lap joints, which could result in rapid 
depressurization and consequent reduced structural integrity of the 
airplane.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the NPRM (80 
FR 39394, July 9, 2015) and the FAA's response to each comment. United 
Airlines concurred with the NPRM.

Request To Correct Typographical Error

    Boeing asked that we correct the reference in the ``Related Service 
Information under 1 CFR part 51'' from ``. . . sections 41, 42, and 
43'' to ``. . . sections 41, 42, and 46.'' Boeing stated that section 
43 should be section 46, and noted that this is a typographical error.
    We agree with the commenter's request for the reason provided. We 
have corrected this typographical error in ``Related Service 
Information under 1 CFR part 51'' accordingly.

Request To Clarify Certain Requirements

    Boeing asked that we clarify paragraph (i)(1) of the proposed AD 
(80 FR 39394, July 9, 2015) by including ``per Table 7'' in that 
paragraph. Boeing also asked that we clarify paragraph (i)(3) of the 
proposed AD by including ``per Table 10'' in that paragraph.
    We agree that clarification is necessary but we do not agree to 
change paragraphs (i)(1) and (i)(3) of this AD. Paragraph (i) of this 
AD specifies doing the applicable inspections in paragraphs (i)(1), 
(i)(2), or (i)(3) of this AD, in accordance with the Accomplishment 
Instructions of the referenced service information; and repeating the 
applicable inspections at the applicable times specified in Tables 7, 
8, 9, and 10 of paragraph 1.E., ``Compliance,'' of Boeing Alert Service 
Bulletin 747-53A2499, Revision 3, dated July 15, 2014. In each of these 
tables the applicable groups are identified and match the groups 
identified in paragraphs (i)(1), (i)(2), and (i)(3) of this AD. We 
refer to the tables in paragraph 1.E., ``Compliance,'' of service 
information for the applicable compliance times and not for how to 
accomplish the required actions. Therefore, we have not changed this AD 
in this regard.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
this AD as proposed, with minor editorial changes. We have determined 
that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM (80 FR 39394, July 9, 2015) for correcting the unsafe condition; 
and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (80 FR 39394, July 9, 2015).

Related Service Information Under 1 CFR Part 51

    We reviewed Boeing Alert Service Bulletin 747-53A2499, Revision 3, 
dated July 15, 2014. The service information describes procedures for 
body skin lap joint inspections and modifications in sections 41, 42, 
and 46. 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 120 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

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