Download as PDF Federal Register / Vol. 81, No. 115 / Wednesday, June 15, 2016 / Rules and Regulations ehiers on DSK5VPTVN1PROD with RULES As with all Federal promotion programs, reports and forms are periodically reviewed to reduce information requirements and duplication by industry and public sector agencies. Finally, USDA has not identified any relevant Federal rules that duplicate, overlap, or conflict with this rule. AMS is committed to complying with the E-Government Act, to promote the use of the Internet and other information technologies to provide increased opportunities for citizen access to Government information and services, and for other purposes. Regarding outreach efforts, the Board met on July 17, 2015, and unanimously recommended these changes to the Order. All of the Board’s meetings, including meetings held via teleconference, are open to the public and interested persons are invited to participate and express their views. A proposed rule concerning this action was published in the Federal Register on March 1, 2016 (81 FR 10530). The proposal was made available through the Internet by USDA and the Office of the Federal Register. A 15-day comment period ending March 16, 2016, was provided to allow interested persons to submit comments. No comments were received. After consideration of all relevant matters presented, including the information and recommendation submitted by the Board and other available information, it is hereby found that this rule, as hereinafter set forth, is consistent with and will effectuate the purposes of the 1996 Act. It is further found that good cause exists for not postponing the effective date of this rule until 30 days after publication in the Federal Register (5 U.S.C. 553) because this is the initial year for the collection of assessments under the Order, on the 2015 harvest, and assessments were due on February 15, 2016. Importers are responsible for paying assessments directly to the Board 30 calendar days after importation. The Board would like to implement this incentive as soon as possible to facilitate the initial collection of assessments. Additionally, this action was unanimously recommended by the Board. Further, a 15-day comment period was provided for in the proposed rule and no comments were received.

[FR Doc. 2016–14150 Filed 6–14–16; 8:45 am] BILLING CODE P PO 00000 Frm 00017 Fmt 4700 Sfmt 4700 Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Final rule. We are adopting a new airworthiness directive (AD) for all Airbus Model A318 series airplanes; A319 series airplanes; A320–211, –212, –214, –231, –232, and –233 airplanes; and A321 series airplanes. This AD was prompted by an evaluation by the design approval holder (DAH) indicating that certain structural repair manual (SRM) inspection requirements for the fuselage skin repairs are insufficient to detect cracks. This AD requires an inspection to determine whether any fuselage external skin (doubler) repairs have been accomplished, an inspection for cracking of certain repaired external fuselage skin areas in the fuselage, and repair if necessary. We are issuing this AD to detect and correct fatigue cracking of the fuselage skin, which could result in reduced structural integrity of the airplane. DATES: This AD becomes effective July 20, 2016. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of July 20, 2016.

SUPPLEMENTARY INFORMATION: ehiers on DSK5VPTVN1PROD with RULES Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all Airbus Model A318 series airplanes; A319 series airplanes; A320– 211, –212, –214, –231, –232, and –233 airplanes; and A321 series airplanes. The NPRM published in the Federal Register on September 28, 2015 (80 FR 58226) (‘‘the NPRM’’). The NPRM was prompted by an evaluation by the DAH indicating that the fuselage skin repairs are subject to WFD. The NPRM proposed to require an inspection to determine whether any fuselage external skin (doubler) repairs have been accomplished, an inspection for cracking of certain repaired external fuselage skin areas in the fuselage, and repair if necessary. We are issuing this AD to detect and correct fatigue cracking of the fuselage skin, which could result in reduced structural integrity of the airplane. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2015–0036R1, dated March 31, 2015 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition on all Airbus Model A318 series airplanes; A319 series airplanes; A320–211, –212, –214, –231, –232, and –233 airplanes, and A321 series airplanes. The MCAI states: During A320 family Extended Service Goal full scale fatigue tests, it was demonstrated that the inspection thresholds defined in the current Structural Repair Manual (SRM) for the A320 family skin repairs are insufficient VerDate Sep<11>2014 14:36 Jun 14, 2016 Jkt 238001 to detect possible cracks becoming after repairs. The findings are limited to 1.2 [millimeter] (mm) fuselage skin and cover for all cut-out external repairs. The internal repairs are not affected. This condition, if not detected and corrected, could affect the structural integrity of the fuselage at the repaired skin area(s). To address this potential unsafe condition, Airbus issued Alert Operators Transmission (AOT) A53N007–14 to provide inspection instructions. For the reasons described above, EASA issued AD 2015–0036 [https:// www.casa.gov.au/scripts/ nc.dll?WCMS:OLDASSET::svPath=/ADFiles/ over/a320/,svFileName=2015-0036.pdf] to require a one-time inspection of the affected areas and, depending on findings, accomplishment of applicable repair instructions. Since that [EASA] AD was issued, operators have questioned the inspection threshold for A318 aeroplanes (not yet in the Airbus AOT), which is actually identical to that for A319 aeroplanes. In addition, an error has been detected in paragraph (1) [of the EASA AD], since external doublers may have been installed in the affected area by a modification that may not be recorded as repair. Such doubler installations are also subject to the inspection requirements of this [EASA] AD, which is therefore revised to provide clarifications, correcting paragraph (1) [of the EASA AD] and introducing a Note. Required actions include an inspection to determine whether any fuselage external skin (doubler) repairs have been accomplished, an external ultrasonic inspection or an internal low/ high frequency eddy current inspection for cracking of certain repaired external fuselage skin areas in the fuselage, and repair if necessary. The compliance times vary depending on airplane configuration. The earliest compliance time is within 25,200 flight cycles since last repair, or within 350 flight cycles after the effective date of the AD, whichever occurs later. The latest compliance time is within 45,000 flight cycles since last repair; within 1,500 flight cycles from the effective date of the AD, without exceeding 49,100 flight cycles since last repair; or within 350 flight cycles since the effective date of the AD; whichever occurs latest. You may examine the MCAI in the AD docket on the Internet at https:// www.regulations.gov by searching for and locating Docket No. FAA–2015– 3635. Comments We gave the public the opportunity to participate in developing this AD. We have considered the comments received. The following presents the comments received on the NPRM and the FAA’s response to each comment. PO 00000 Frm 00018 Fmt 4700 Sfmt 4700 Support for the NPRM Mr. Bryant Kerr stated that the NPRM is an excellent idea, and it is always worth improving safety on airplanes. Request To Revise Applicability United Airlines (UAL) requested that we revise the NPRM applicability to apply only to airplanes having repairs that were completed before May 1, 2015, the date of the revised service repair manual (SRM). UAL stated that any new airplane deliveries or external repairs accomplished after the updated SRM thresholds will presumably have the correct thresholds contained in the maintenance/inspection program. We partially agree with UAL’s request. We agree that airplanes with repairs accomplished using the updated SRM will be in compliance with certain sections of this AD, such as the timescale for the inspection, which is a subset of the AD requirements. However, the SRM update will not replace the remaining AD requirements, which must be applicable to all airplanes identified in paragraph (c) of this AD. We have not changed this AD in this regard. Request To Exclude Inspected Airplanes Delta Airlines (DAL) stated that since certain repairs and modifications on its airplanes have already had their first inspection prior to the compliance time specified in the NPRM, the NPRM requirements should not apply. DAL also stated that if an operator’s maintenance/inspection program is more stringent than the requirements of paragraph (m) of the proposed AD, the operator should be excluded from the NPRM requirements. We disagree with DAL’s request. Accomplishment of the first inspection is only part of the actions required by this AD. Paragraph (m) of this AD requires revision of the post-repair inspection threshold(s) in the operator’s maintenance program or inspection program. This AD includes the minimum requirements for mitigating the identified unsafe condition. However, under the provisions of paragraph (n)(1) of this AD, we will consider requests for approval of different methods of compliance if sufficient data are submitted to substantiate that the change would provide an acceptable level of safety. We have not changed this AD in this regard. Request To Revise Compliance Time DAL requested a compliance time extension from 350 flight cycles to 6 months. DAL stated that depending on E:\FR\FM\15JNR1.SGM 15JNR1 Federal Register / Vol. 81, No. 115 / Wednesday, June 15, 2016 / Rules and Regulations Request To Clarify Inspection Timeframes Request To Clarify Requirements and Approve Certain Repair Information Sources ehiers on DSK5VPTVN1PROD with RULES the fleet utilization, an operator of a large, older fleet could be required to accomplish the compliance rework within a few months, thereby creating a significant impact on its available resources. DAL also stated that it is possible that several airplanes will be grounded because it may not have enough resources to comply with the 350-flight-cycle limit. We do not agree with DAL’s request. DAL’s rationale for a compliance time extension does not provide an acceptable level of safety. The compliance time of this AD is based on a risk assessment. Some safety issues are more time sensitive than others. We have considered the compliance time established by EASA, and the overall risk to the fleet, including the severity of the identified unsafe condition and the likelihood of the occurrence of the unsafe condition, to determine the compliance time. However, under the provisions of paragraph (n)(1) of this AD, operators may apply for an extension of the compliance time by providing a satisfactory rationale explaining why a compliance time extension provides an acceptable level of safety. We have not changed this final rule in this regard. Request To Correct Non-Destructive Testing Manual (NTM) Task Numbers DAL requested that we make a distinction that the NPRM requirements apply only to external repair fasteners common to the 1.2-millimeter (mm) skin. DAL also stated that we should approve category B repairs done using the latest revision of the SRM and any repair design approval sheet (RDAS) approved after July 1, 2014. DAL stated that the applicable Airbus SRM repair inspection thresholds have been revised this year to address certain inadequacies. We do not agree with DAL’s requests. Paragraph (g) of this AD already requires an inspection to determine whether any fuselage doubler repairs have been accomplished on affected fuselage sections with a skin thickness of 1.2 mm. DAL did not substantiate how the corrective actions in any RDAS for category ‘‘B’’ repairs approved after July 1, 2014, and the latest revision of the SRMs would adequately address the unsafe condition. However, the commenter may use the provisions of paragraph (n)(2) of this AD for obtaining corrective actions from a manufacturer. We have not changed this AD in this regard. VerDate Sep<11>2014 14:36 Jun 14, 2016 Jkt 238001 UAL requested clarification on how the NPRM addresses detection of cracking in the timeframe between the inspection threshold specified in the NPRM and Airbus Alert Operators Transmission A53N007–14, dated July 22, 2014, and the repetitive inspections specified in the SRM. UAL stated that the compliance time has a short threshold if the repair records are inconclusive, which is as early as 350 flight cycles from the effective date of the AD; therefore, the initial inspection could be accomplished much earlier than the crack detection period. We agree to clarify the inspection timeframes. The 350-flight-cycle compliance time is a second option to the compliance time specified in Airbus Alert Operators Transmission A53N007–14, dated July 22, 2014. The compliance time is based on a risk assessment that takes into consideration the fatigue crack length propagation. We have considered the compliance time established by EASA, and the overall risk to the fleet, including the severity of the identified unsafe condition and the likelihood of the occurrence of the unsafe condition. No change to the AD is necessary in this regard. DAL stated that Airbus Alert Operators Transmission A53N007–14, dated July 22, 2014, references incorrect formatting of NTM task numbers. DAL stated the formatting should be ‘‘51–10– 15–270–801–A01’’ and ‘‘51–10–16–250– 801–A01,’’ and not ‘‘51–10–15–270– 801–A–01’’ and ‘‘51–10–16–250–801– A–01.’’ We disagree with DAL’s statement. NTM task numbers 51–10–15–270–801– A–01 and 51–10–16–250–801–A–01 are correctly referenced in Airbus Alert Operators Transmission A53N007–14, dated July 22, 2014, and in the Airbus A318/319/320/321 Non-Destructive Testing Manual. We have not changed this AD in this regard. Clarification of Unsafe Condition Language We revised the description of the precipitating event in the SUMMARY and paragraph (e) of this AD to correspond to the wording used in the MCAI AD. 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 except for minor editorial PO 00000 Frm 00019 Fmt 4700 Sfmt 4700 38899 changes. We have determined that these minor changes: • Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM. We also determined that these changes will not increase the economic burden on any operator or increase the scope of this AD. Related Service Information Under 1 CFR Part 51 Airbus has issued Alert Operators Transmission A53N007–14, dated July 22, 2014. The service information describes procedures for an inspection to detect cracking on repaired 1.2millimeter fuselage skin areas on fuselage sections 11, 12, 13, 14, 16, and 17 at external doubler repairs. 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 940 airplanes of U.S. registry. We also estimate that it will take about 2 work-hours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of this AD on U.S. operators to be $159,800, or $170 per product. We have received no definitive data that would enable us to provide cost estimates 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. E:\FR\FM\15JNR1.SGM 15JNR1 38900 Federal Register / Vol. 81, No. 115 / Wednesday, June 15, 2016 / Rules and Regulations Regulatory Findings We 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 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.

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 Airbus Model A318 
series airplanes; A319 series airplanes; A320-211, -212, -214, -231, -
232, and -233 airplanes; and A321 series airplanes. The NPRM published 
in the Federal Register on September 28, 2015 (80 FR 58226) (``the 
NPRM''). The NPRM was prompted by an evaluation by the DAH indicating 
that the fuselage skin repairs are subject to WFD. The NPRM proposed to 
require an inspection to determine whether any fuselage external skin 
(doubler) repairs have been accomplished, an inspection for cracking of 
certain repaired external fuselage skin areas in the fuselage, and 
repair if necessary. We are issuing this AD to detect and correct 
fatigue cracking of the fuselage skin, which could result in reduced 
structural integrity of the airplane.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2015-0036R1, dated March 31, 2015 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition on all Airbus Model A318 
series airplanes; A319 series airplanes; A320-211, -212, -214, -231, -
232, and -233 airplanes, and A321 series airplanes. The MCAI states:

    During A320 family Extended Service Goal full scale fatigue 
tests, it was demonstrated that the inspection thresholds defined in 
the current Structural Repair Manual (SRM) for the A320 family skin 
repairs are insufficient to detect possible cracks becoming after 
repairs. The findings are limited to 1.2 [millimeter] (mm) fuselage 
skin and cover for all cut-out external repairs. The internal 
repairs are not affected.
    This condition, if not detected and corrected, could affect the 
structural integrity of the fuselage at the repaired skin area(s).
    To address this potential unsafe condition, Airbus issued Alert 
Operators Transmission (AOT) A53N007-14 to provide inspection 
instructions.
    For the reasons described above, EASA issued AD 2015-0036 
[https://www.casa.gov.au/scripts/nc.dll?WCMS:OLDASSET::svPath=/ADFiles/over/a320/,svFileName=2015-0036.pdf] to require a one-time 
inspection of the affected areas and, depending on findings, 
accomplishment of applicable repair instructions.
    Since that [EASA] AD was issued, operators have questioned the 
inspection threshold for A318 aeroplanes (not yet in the Airbus 
AOT), which is actually identical to that for A319 aeroplanes. In 
addition, an error has been detected in paragraph (1) [of the EASA 
AD], since external doublers may have been installed in the affected 
area by a modification that may not be recorded as repair.
    Such doubler installations are also subject to the inspection 
requirements of this [EASA] AD, which is therefore revised to 
provide clarifications, correcting paragraph (1) [of the EASA AD] 
and introducing a Note.

    Required actions include an inspection to determine whether any 
fuselage external skin (doubler) repairs have been accomplished, an 
external ultrasonic inspection or an internal low/high frequency eddy 
current inspection for cracking of certain repaired external fuselage 
skin areas in the fuselage, and repair if necessary. The compliance 
times vary depending on airplane configuration. The earliest compliance 
time is within 25,200 flight cycles since last repair, or within 350 
flight cycles after the effective date of the AD, whichever occurs 
later. The latest compliance time is within 45,000 flight cycles since 
last repair; within 1,500 flight cycles from the effective date of the 
AD, without exceeding 49,100 flight cycles since last repair; or within 
350 flight cycles since the effective date of the AD; whichever occurs 
latest. You may examine the MCAI in the AD docket on the Internet at 
https://www.regulations.gov by searching for and locating Docket No. 
FAA-2015-3635.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We have considered the comments received. The following 
presents the comments received on the NPRM and the FAA's response to 
each comment.

Support for the NPRM

    Mr. Bryant Kerr stated that the NPRM is an excellent idea, and it 
is always worth improving safety on airplanes.

Request To Revise Applicability

    United Airlines (UAL) requested that we revise the NPRM 
applicability to apply only to airplanes having repairs that were 
completed before May 1, 2015, the date of the revised service repair 
manual (SRM). UAL stated that any new airplane deliveries or external 
repairs accomplished after the updated SRM thresholds will presumably 
have the correct thresholds contained in the maintenance/inspection 
program.
    We partially agree with UAL's request. We agree that airplanes with 
repairs accomplished using the updated SRM will be in compliance with 
certain sections of this AD, such as the timescale for the inspection, 
which is a subset of the AD requirements. However, the SRM update will 
not replace the remaining AD requirements, which must be applicable to 
all airplanes identified in paragraph (c) of this AD. We have not 
changed this AD in this regard.

Request To Exclude Inspected Airplanes

    Delta Airlines (DAL) stated that since certain repairs and 
modifications on its airplanes have already had their first inspection 
prior to the compliance time specified in the NPRM, the NPRM 
requirements should not apply. DAL also stated that if an operator's 
maintenance/inspection program is more stringent than the requirements 
of paragraph (m) of the proposed AD, the operator should be excluded 
from the NPRM requirements.
    We disagree with DAL's request. Accomplishment of the first 
inspection is only part of the actions required by this AD. Paragraph 
(m) of this AD requires revision of the post-repair inspection 
threshold(s) in the operator's maintenance program or inspection 
program. This AD includes the minimum requirements for mitigating the 
identified unsafe condition. However, under the provisions of paragraph 
(n)(1) of this AD, we will consider requests for approval of different 
methods of compliance if sufficient data are submitted to substantiate 
that the change would provide an acceptable level of safety. We have 
not changed this AD in this regard.

Request To Revise Compliance Time

    DAL requested a compliance time extension from 350 flight cycles to 
6 months. DAL stated that depending on

[[Page 38899]]

the fleet utilization, an operator of a large, older fleet could be 
required to accomplish the compliance rework within a few months, 
thereby creating a significant impact on its available resources. DAL 
also stated that it is possible that several airplanes will be grounded 
because it may not have enough resources to comply with the 350-flight-
cycle limit.
    We do not agree with DAL's request. DAL's rationale for a 
compliance time extension does not provide an acceptable level of 
safety. The compliance time of this AD is based on a risk assessment. 
Some safety issues are more time sensitive than others. We have 
considered the compliance time established by EASA, and the overall 
risk to the fleet, including the severity of the identified unsafe 
condition and the likelihood of the occurrence of the unsafe condition, 
to determine the compliance time. However, under the provisions of 
paragraph (n)(1) of this AD, operators may apply for an extension of 
the compliance time by providing a satisfactory rationale explaining 
why a compliance time extension provides an acceptable level of safety. 
We have not changed this final rule in this regard.

Request To Clarify Requirements and Approve Certain Repair Information 
Sources

    DAL requested that we make a distinction that the NPRM requirements 
apply only to external repair fasteners common to the 1.2-millimeter 
(mm) skin. DAL also stated that we should approve category B repairs 
done using the latest revision of the SRM and any repair design 
approval sheet (RDAS) approved after July 1, 2014. DAL stated that the 
applicable Airbus SRM repair inspection thresholds have been revised 
this year to address certain inadequacies.
    We do not agree with DAL's requests. Paragraph (g) of this AD 
already requires an inspection to determine whether any fuselage 
doubler repairs have been accomplished on affected fuselage sections 
with a skin thickness of 1.2 mm. DAL did not substantiate how the 
corrective actions in any RDAS for category ``B'' repairs approved 
after July 1, 2014, and the latest revision of the SRMs would 
adequately address the unsafe condition. However, the commenter may use 
the provisions of paragraph (n)(2) of this AD for obtaining corrective 
actions from a manufacturer. We have not changed this AD in this 
regard.

Request To Clarify Inspection Timeframes

    UAL requested clarification on how the NPRM addresses detection of 
cracking in the timeframe between the inspection threshold specified in 
the NPRM and Airbus Alert Operators Transmission A53N007-14, dated July 
22, 2014, and the repetitive inspections specified in the SRM. UAL 
stated that the compliance time has a short threshold if the repair 
records are inconclusive, which is as early as 350 flight cycles from 
the effective date of the AD; therefore, the initial inspection could 
be accomplished much earlier than the crack detection period.
    We agree to clarify the inspection timeframes. The 350-flight-cycle 
compliance time is a second option to the compliance time specified in 
Airbus Alert Operators Transmission A53N007-14, dated July 22, 2014. 
The compliance time is based on a risk assessment that takes into 
consideration the fatigue crack length propagation. We have considered 
the compliance time established by EASA, and the overall risk to the 
fleet, including the severity of the identified unsafe condition and 
the likelihood of the occurrence of the unsafe condition. No change to 
the AD is necessary in this regard.

Request To Correct Non-Destructive Testing Manual (NTM) Task Numbers

    DAL stated that Airbus Alert Operators Transmission A53N007-14, 
dated July 22, 2014, references incorrect formatting of NTM task 
numbers. DAL stated the formatting should be ``51-10-15-270-801-A01'' 
and ``51-10-16-250-801-A01,'' and not ``51-10-15-270-801-A-01'' and 
``51-10-16-250-801-A-01.''
    We disagree with DAL's statement. NTM task numbers 51-10-15-270-
801-A-01 and 51-10-16-250-801-A-01 are correctly referenced in Airbus 
Alert Operators Transmission A53N007-14, dated July 22, 2014, and in 
the Airbus A318/319/320/321 Non-Destructive Testing Manual. We have not 
changed this AD in this regard.

Clarification of Unsafe Condition Language

    We revised the description of the precipitating event in the 
SUMMARY and paragraph (e) of this AD to correspond to the wording used 
in the MCAI AD.

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 except for minor editorial changes. We have 
determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this AD.

Related Service Information Under 1 CFR Part 51

    Airbus has issued Alert Operators Transmission A53N007-14, dated 
July 22, 2014. The service information describes procedures for an 
inspection to detect cracking on repaired 1.2-millimeter fuselage skin 
areas on fuselage sections 11, 12, 13, 14, 16, and 17 at external 
doubler repairs. 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 940 airplanes of U.S. registry.
    We also estimate that it will take about 2 work-hours per product 
to comply with the basic requirements of this AD. The average labor 
rate is $85 per work-hour. Based on these figures, we estimate the cost 
of this AD on U.S. operators to be $159,800, or $170 per product.
    We have received no definitive data that would enable us to provide 
cost estimates 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.

[[Page 38900]]

Regulatory Findings

    We 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 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.
