SUPPLEMENTARY INFORMATION: Discussion On March 22, 2016, at 81 FR 15171, the Federal Register published our PO 00000 Frm 00014 Fmt 4700 Sfmt 4700 notice of proposed rulemaking (NPRM), which proposed to amend 14 CFR part 39 by adding an AD that would apply to Agusta S.p.A. Model A109A, A109A II, A109C, A109E, A109K2, A109S, and AW109SP helicopters with a drive shaft part number (P/N) 109–8412–02–1 or 109–8412–02–3 installed. The NPRM proposed to require visually inspecting the drive shaft for a crack. The proposed requirements were intended to detect a crack on the drive shaft to prevent failure of the driveshaft, failure of the tail rotor, and subsequent loss of helicopter control. The NPRM was prompted by AD No. 2015–0054, dated March 27, 2015, issued by EASA, which is the Technical Agent for the Member States of the European Union, to correct an unsafe condition for the Model A109A with retrofit kit P/N 109–0820–27–101 installed, and Model A109A II, A109C, A109E, A109K2, A109LUH, A109S, and AW109SP helicopters. EASA advises that during scheduled maintenance on a Model A109S helicopter, three cracks were found on the drive shaft. An investigation could not determine the cause of the cracking but concluded it could not have been caused by fatigue. This condition, if not detected and corrected, could lead to tail rotor failure, possibly resulting in loss of helicopter control, EASA advises. EASA AD No. 2015–0054 consequently requires a one-time inspection of the drive shaft, and replacing the drive shaft if cracks are found. Comments We gave the public the opportunity to participate in developing this AD, but we received no comments on the NPRM (81 FR 15171, March 22, 2016). FAA’s Determination These helicopters have been approved by the aviation authority of Italy and are approved for operation in the United States. Pursuant to our bilateral agreement with Italy, EASA, its technical representative, has notified us of the unsafe condition described in the EASA AD. We are issuing this AD because we evaluated all information provided by EASA and determined the unsafe condition exists and is likely to exist or develop on other helicopters of these same type designs and that air safety and the public interest require adopting the AD requirements as proposed. Interim Action We consider this AD to be an interim action. The design approval holder has not determined the cause of the unsafe E:\FR\FM\15SER1.SGM 15SER1 Federal Register / Vol. 81, No. 179 / Thursday, September 15, 2016 / Rules and Regulations condition identified in this AD. If a cause is determined and actions developed to address the cause, we might consider additional rulemaking. Differences Between This AD and the EASA AD The EASA AD applies to Agusta Model A109LUH helicopters. This AD does not because this model does not have an FAA type certificate. Related Service Information Under 1 CFR Part 51 We reviewed AgustaWestland Bollettino Tecnico (BT) No. 109–147 for Model A109A helicopters with retrofit kit P/N 109–0820–27–101 installed, Model A109A II, and Model A109C helicopters; BT No. 109EP–143 for Model A109E helicopters; BT No. 109K– 68 for Model A109K2 helicopters; BT No. 109S–067 for Model A109S helicopters; and BT No. 109SP–094 for Model AW109SP helicopters. All of the BTs are dated March 25, 2015. AgustaWestland reports that during a scheduled servicing of an A109S helicopter, three cracks were found on drive shaft, P/N 109–8412–02–1. The BTs prescribe a one-time drive shaft inspection for cracks. 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. rmajette on DSK2TPTVN1PROD with RULES Costs of Compliance We estimate that this AD affects 142 helicopters of U.S. Registry and that labor costs average $85 per work-hour. Based on these estimates, we expect the following costs: • Inspecting the drive shaft requires 9 work-hours and no parts. The estimated cost is $765 per helicopter and $108,630 for the U.S. fleet. • Replacing the drive shaft requires no additional labor hours. Parts cost $6,082 per helicopter. According to Agusta service information, some of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage by Agusta. Accordingly, we have included all costs in our cost estimate. 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. VerDate Sep<11>2014 14:38 Sep 14, 2016 Jkt 238001 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 helicopters identified in this rulemaking action. Regulatory Findings This AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government. For the reasons discussed above, I certify that this AD: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866; (2) Is not a ‘‘significant rule’’ under DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); (3) Will not affect intrastate aviation in Alaska to the extent that it justifies making a regulatory distinction; 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. We prepared an economic evaluation of the estimated costs to comply with this AD and placed it in the AD docket.

ACTION: Notice of comparability determination for margin requirements for uncleared swaps under the laws of Japan. rmajette on DSK2TPTVN1PROD with RULES AGENCY: The following is the analysis and determination of the Commodity Futures Trading Commission (‘‘Commission’’) regarding a request by the Japan Financial Services Agency 14:38 Sep 14, 2016 Jkt 238001 U.S.C. 1 et. seq. 7 U.S.C. 6s(e)(1)(B). SDs and MSPs for which there is a Prudential Regulator must meet the margin requirements for uncleared swaps established by the applicable Prudential Regulator. 7 U.S.C. 6s(e)(1)(A). See also 7 U.S.C. 1a(39) (defining the term ‘‘Prudential Regulator’’ to include the Board of Governors of the Federal Reserve System; the Office of the Comptroller of the Currency; the Federal Deposit Insurance Corporation; the Farm Credit Administration; and the Federal Housing Finance Agency). The Prudential Regulators published final margin requirements in November 2015. See Margin and Capital Requirements for Covered Swap Entities, 80 FR 74840 (Nov. 30, 2015) (‘‘Prudential Regulators’ Final Margin Rule’’). 3 See Margin Requirements for Uncleared Swaps for Swap Dealers and Major Swap Participants, 81 FR 636 (Jan. 6, 2016). The Margin Rule, which became effective April 1, 2016, is codified in part 23 of the Commission’s regulations. See 17 CFR 23.150 through 23.159, and 23.161. The Commission’s regulations are found in chapter I of Title 17 of the Code of Federal Regulations, 17 CFR 1 et. seq. 2 See 17 CFR Chapter I VerDate Sep<11>2014 I. Introduction Pursuant to section 4s(e) of the CEA,1 the Commission is required to promulgate margin requirements for uncleared swaps applicable to each SD and MSP for which there is no Prudential Regulator (collectively, ‘‘Covered Swap Entities’’ or ‘‘CSEs’’).2 The Commission published final margin requirements for such CSEs in January 2016 (the ‘‘Final Margin Rule’’).3 Subsequently, on May 31, 2016, the Commission published in the Federal Register its final rule with respect to the cross-border application of the 17 COMMODITY FUTURES TRADING COMMISSION SUMMARY: (‘‘JFSA’’) that the Commission determine that laws and regulations applicable in Japan provide a sufficient basis for an affirmative finding of comparability with respect to margin requirements for uncleared swaps applicable to certain swap dealers (‘‘SDs’’) and major swap participants (‘‘MSPs’’) registered with the Commission. As discussed in detail herein, with one exception, the Commission has found the margin requirements for uncleared swaps under the laws and regulations of Japan comparable to those under the Commodity Exchange Act (‘‘CEA’’) and Commission regulations.

SUPPLEMENTARY INFORMATION: PO 00000 Frm 00016 Fmt 4700 Sfmt 4700 Commission’s margin requirements for uncleared swaps applicable to CSEs (hereinafter, the ‘‘Cross-Border Margin Rule’’).4 The Cross-Border Margin Rule sets out the circumstances under which a CSE is allowed to satisfy the requirements under the Margin Rule by complying with comparable foreign margin requirements (‘‘substituted compliance’’); offers certain CSEs a limited exclusion from the Commission’s margin requirements; and outlined a framework for assessing whether a foreign jurisdiction’s margin requirements are comparable to the Final Margin Rule (‘‘comparability determinations’’). The Commission promulgated the Cross-Border Margin Rule after close consultation with the Prudential Regulators and in light of comments from and discussions with market participants and foreign regulators.5 On June 17, 2016, the JFSA (the ‘‘applicant’’) submitted a request that the Commission determine that laws and regulations applicable in Japan provide a sufficient basis for an affirmative finding of comparability with respect to the Final Margin Rule. The applicant provided Commission staff with an updated submission on July 26, 2016. On August 18, 2016, the application was further supplemented with corrections and additional materials. The Commission’s analysis and comparability determination for Japan regarding the Final Margin Rule is detailed below. 4 See Margin Requirements for Uncleared Swaps for Swap Dealers and Major Swap Participants— Cross-Border Application of the Margin Requirements, 81 FR 34818 (May 31, 2016). The Cross-Border Margin Rule, which became effective August 1, 2016, is codified in part 23 of the Commission’s regulations. See 17 CFR 23.160. 5 In 2014, in conjunction with re-proposing its margin requirements, the Commission requested comment on three alternative approaches to the cross-border application of its margin requirements: (i) A transaction-level approach consistent with the Commission’s guidance on the cross-border application of the CEA’s swap provisions, see Interpretive Guidance and Policy Statement Regarding Compliance with Certain Swap Regulations, 78 FR 45292 (July 26, 2013) (the ‘‘Guidance’’); (ii) an approach consistent with the Prudential Regulators’ proposed cross-border framework for margin, see Margin and Capital Requirements for Covered Swap Entities, 79 FR 57348 (Sept. 24, 2014); and (iii) an entity-level approach that would apply margin rules on a firmwide basis (without any exclusion for swaps with non-U.S. counterparties). See Margin Requirements for Uncleared Swaps for Swap Dealers and Major Swap Participants, 79 FR 59898 (Oct. 3, 2014). Following a review of comments received in response to this release, the Commission’s Global Markets Advisory Committee (‘‘GMAC’’) hosted a public panel discussion on the cross-border application of margin requirements.

SUPPLEMENTARY INFORMATION: 

Discussion

    On March 22, 2016, at 81 FR 15171, the Federal Register published 
our notice of proposed rulemaking (NPRM), which proposed to amend 14 
CFR part 39 by adding an AD that would apply to Agusta S.p.A. Model 
A109A, A109A II, A109C, A109E, A109K2, A109S, and AW109SP helicopters 
with a drive shaft part number (P/N) 109-8412-02-1 or 109-8412-02-3 
installed. The NPRM proposed to require visually inspecting the drive 
shaft for a crack. The proposed requirements were intended to detect a 
crack on the drive shaft to prevent failure of the driveshaft, failure 
of the tail rotor, and subsequent loss of helicopter control.
    The NPRM was prompted by AD No. 2015-0054, dated March 27, 2015, 
issued by EASA, which is the Technical Agent for the Member States of 
the European Union, to correct an unsafe condition for the Model A109A 
with retrofit kit P/N 109-0820-27-101 installed, and Model A109A II, 
A109C, A109E, A109K2, A109LUH, A109S, and AW109SP helicopters.
    EASA advises that during scheduled maintenance on a Model A109S 
helicopter, three cracks were found on the drive shaft. An 
investigation could not determine the cause of the cracking but 
concluded it could not have been caused by fatigue. This condition, if 
not detected and corrected, could lead to tail rotor failure, possibly 
resulting in loss of helicopter control, EASA advises. EASA AD No. 
2015-0054 consequently requires a one-time inspection of the drive 
shaft, and replacing the drive shaft if cracks are found.

Comments

    We gave the public the opportunity to participate in developing 
this AD, but we received no comments on the NPRM (81 FR 15171, March 
22, 2016).

FAA's Determination

    These helicopters have been approved by the aviation authority of 
Italy and are approved for operation in the United States. Pursuant to 
our bilateral agreement with Italy, EASA, its technical representative, 
has notified us of the unsafe condition described in the EASA AD. We 
are issuing this AD because we evaluated all information provided by 
EASA and determined the unsafe condition exists and is likely to exist 
or develop on other helicopters of these same type designs and that air 
safety and the public interest require adopting the AD requirements as 
proposed.

Interim Action

    We consider this AD to be an interim action. The design approval 
holder has not determined the cause of the unsafe

[[Page 63375]]

condition identified in this AD. If a cause is determined and actions 
developed to address the cause, we might consider additional 
rulemaking.

Differences Between This AD and the EASA AD

    The EASA AD applies to Agusta Model A109LUH helicopters. This AD 
does not because this model does not have an FAA type certificate.

Related Service Information Under 1 CFR Part 51

    We reviewed AgustaWestland Bollettino Tecnico (BT) No. 109-147 for 
Model A109A helicopters with retrofit kit P/N 109-0820-27-101 
installed, Model A109A II, and Model A109C helicopters; BT No. 109EP-
143 for Model A109E helicopters; BT No. 109K-68 for Model A109K2 
helicopters; BT No. 109S-067 for Model A109S helicopters; and BT No. 
109SP-094 for Model AW109SP helicopters. All of the BTs are dated March 
25, 2015. AgustaWestland reports that during a scheduled servicing of 
an A109S helicopter, three cracks were found on drive shaft, P/N 109-
8412-02-1. The BTs prescribe a one-time drive shaft inspection for 
cracks.
    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 142 helicopters of U.S. Registry 
and that labor costs average $85 per work-hour. Based on these 
estimates, we expect the following costs:
     Inspecting the drive shaft requires 9 work-hours and no 
parts. The estimated cost is $765 per helicopter and $108,630 for the 
U.S. fleet.
     Replacing the drive shaft requires no additional labor 
hours. Parts cost $6,082 per helicopter.
    According to Agusta service information, some of the costs of this 
AD may be covered under warranty, thereby reducing the cost impact on 
affected individuals. We do not control warranty coverage by Agusta. 
Accordingly, we have included all costs in our cost estimate.

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 helicopters identified in this 
rulemaking action.

Regulatory Findings

    This AD will not have federalism implications under Executive Order 
13132. This AD will not have a substantial direct effect on the States, 
on the relationship between the national government and the States, or 
on the distribution of power and responsibilities among the various 
levels of government.
    For the reasons discussed above, I certify that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866;
    (2) Is not a ``significant rule'' under DOT Regulatory Policies and 
Procedures (44 FR 11034, February 26, 1979);
    (3) Will not affect intrastate aviation in Alaska to the extent 
that it justifies making a regulatory distinction; 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.
    We prepared an economic evaluation of the estimated costs to comply 
with this AD and placed it in the AD docket.
