AGENCY: On February 8, 2016, the Department of the Treasury published an interim rule (hereafter, the interim rule) implementing the Capital Magnet Fund (CMF), administered by the Community Development Financial Institutions Fund (CDFI Fund). The interim rule incorporates updates to the definitions, requirements and parameters for CMF implementation and administration. This document extends the comment period on the interim rule to May 8, 2016. DATES: The comment period for the interim rule published February 8, 2016, at 81 FR 6434, is extended. All comments must be written and must be received in the offices of the CDFI Fund on or before May 8, 2016. ADDRESSES: You may submit comments concerning the interim rule via the Federal e-Rulemaking Portal at http:// www.regulations.gov (please follow the instructions for submitting comments). All submissions must include the agency name and Regulatory Information Number (RIN) for this rulemaking. Information regarding the CDFI Fund and its programs may be obtained through the CDFI Fund’s Web site at http://www.cdfifund.gov. FOR FURTHER INFORMATION CONTACT: Marcia Sigal, CMF program staff by email at cmf@cdfi.treas.gov, or by phone at (202) 653–0421. SUPPLEMENTARY INFORMATION: On February 8, 2016, the Department of the Treasury published an interim rule implementing the CMF, administered by the CDFI Fund. The comment period designated in the interim rule notice will close on April 8, 2016. The FY 2016 CMF application round opened on February 8, 2016 with the publication in the Federal Register of the Notice of Funds Availability Inviting Applications for the Fiscal Year (FY) 2016 Funding Round of the Capital Magnet Fund (FY 2016 NOFA). Per the FY 2016 NOFA, applications are due by March 30, 2016. The CDFI Fund also held a series of asabaliauskas on DSK3SPTVN1PROD with RULES SUMMARY: VerDate Sep<11>2014 15:58 Mar 16, 2016 Jkt 238001 application webinars for the FY 2016 CMF application round in February and March of 2016. Since the opening of the FY 2016 CMF application round and during these application webinars, multiple interested applicants requested additional time to submit comments regarding the interim rule and requested that the comment period be extended. In response to these requests, the Department hereby extends the comment period for an additional 30 days so that comments are due on or before May 8, 2016. The interim rule incorporates updates to the definitions, requirements and parameters for CMF implementation and administration including, among others, Applicant eligibility, application review, Recipient selection, Assistance Agreements, eligible uses of CMF Awards, and Recipient reporting. In addition, sections of the interim rule regarding certain definitions and project level requirements have been revised in order to facilitate alignment and ease of administration. These revisions are modeled after the requirements of the Low Income Housing Tax Credit Program (LIHTC Program) authorized under Title I of the U.S. Housing Act of 1937, as amended, 42 U.S.C. 1437 et seq., and the HOME Investment Partnership Program (HOME Program) authorized under Title II of the Cranston-Gonzalez National Affordable Housing Act, as amended, 42 U.S.C. 12701 et seq. and the HOME Program final rule published on July 24, 2013. The interim rule also reflects requirements set forth in a final rule, Uniform Administrative Requirements, Cost Principles and Audit Requirements for Federal Awards (12 CFR 1000), adopted by the Department of the Treasury on December 19, 2014 (hereafter referred to as the Uniform Administrative Requirements). The Uniform Administrative Requirements constitute a government-wide framework for grants management codified by the Office of Management and Budget (OMB), combining several OMB grants management circulars aimed at reducing the administrative burden for Recipients, and reducing the risk of waste, fraud and abuse of Federal financial assistance. The Uniform Administrative Requirements establish financial, administrative, procurement, and program management standards with which Federal award-making programs, including those administered by the CDFI Fund, and Recipients must comply. Accordingly, the interim rule includes revisions necessary to implement the Uniform Administrative Requirements, as well as to make certain technical corrections and certain PO 00000 Frm 00002 Fmt 4700 Sfmt 4700 programmatic updates, as well as provide clarifying language to existing program requirements. The CDFI Fund seeks public comment on the entire interim rule. All capitalized terms herein are defined in the definitions section of the interim rule, as set forth in 12 CFR 1807.104.

Turboshaft Engines Federal Aviation Administration (FAA), DOT. ACTION: Final rule. AGENCY: We are superseding airworthiness directive (AD) 2006–23– 17 for certain Turbomeca S.A. Turmo IV A and IV C turboshaft engines. AD 2006–23–17 required repetitive inspections of the centrifugal compressor intake wheel (inducer) blades for cracks and corrosion, replacement of parts that fail inspection, and replacement of the TU 197 standard centrifugal compressor. This AD requires the same inspections, but at revised intervals, adds the replacement of the TU 215 standard centrifugal compressor, and requires replacement of parts that fail inspection. This AD was prompted by a centrifugal compressor inducer blade loss. This AD was also prompted by a Turbomeca S.A. review of the engine service experience and their determination that more frequent borescope inspections (BSIs) are required on engines not modified to the TU 191, TU 197, or TU 224 standard. We are issuing this AD to prevent failure of the centrifugal compressor inducer, which could lead to an uncontained blade release, damage to the engine, and damage to the airplane. DATES: This AD is effective April 21, 2016. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of April 21, 2016.

SUPPLEMENTARY INFORMATION: asabaliauskas on DSK3SPTVN1PROD with RULES Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2006–23–17, Amendment 39–14829 (71 FR 66664, November 16, 2006), (‘‘AD 2006–23– 17’’). AD 2006–23–17 applied to the specified products. The NPRM published in the Federal Register on November 25, 2015 (80 FR 73681). The NPRM proposed to require the same inspections, but at revised intervals, add the replacement of the TU 215 standard centrifugal compressor, and require replacement of parts that fail inspection. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (80 FR 73681, November 25, 2015). Conclusion We reviewed the available data and determined that air safety and the VerDate Sep<11>2014 15:58 Mar 16, 2016 Jkt 238001 public interest require adopting this AD as proposed. Related Service Information Under 1 CFR Part 51 We reviewed Turbomeca S.A. Alert Mandatory Service Bulletin (MSB) No. A249 72 0100, Version H, dated May 21, 2015. The Alert MSB describes procedures for the inspection and replacement of the centrifugal compressor inducer blades. 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 36 engines installed on airplanes of U.S. registry. We estimate that two of these engines will require compressor replacement. We also estimate that about 40 hours per engine are required to comply with this AD. The average labor rate is $85 per hour. Parts cost about $40,000 per engine. Based on these figures, we estimate the cost of this AD on U.S. operators to be $202,400. 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 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: PO 00000 Frm 00003 Fmt 4700 Sfmt 4700 14371 (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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends part 39 of the Federal Aviation Regulations (14 CFR part 39) as follows: PART 39—AIRWORTHINESS DIRECTIVES 1.

Background On April 17, 2015, SIPC filed a proposed rule change with the Commission under section 3(e)(2)(A) of the Securities Investor Protection Act of 1970 (‘‘SIPA’’),1 and subsequently filed amendments to the proposed rule change on June 23, 2015, July 24, 2015, and September 29, 2015. The proposed rule change would add SIPC Rule 600 (‘‘Rule 600’’), entitled ‘‘Rules Relating to Supplemental Report of SIPC Membership.’’ Notice requesting comment on the proposed rule change, as amended, was published in the Federal Register on November 4, 2015.2 The Commission received one comment on the proposal.3 The Commission is approving the proposed rule change under section 3(e)(2) of SIPA.4 II. Proposed Rule Change Pursuant to SIPA and SIPC Bylaws, broker-dealers that are SIPC members pay semi-annual assessments to SIPC at the mid-point and at the end of their fiscal year.5 The assessment payments are the main source of funding for the SIPC Fund. The amount of the assessment a broker-dealer must pay is based on the firm’s revenues from its securities business.6 Consequently, in relation to the payment of the assessments, a broker-dealer must file with SIPC a Form SIPC–6 (General Assessment Payment Form) with the mid-year assessment and a Form SIPC– 7 (General Assessment Reconciliation Form) with the year-end assessment. These forms show the broker-dealer’s calculation of the assessment amount based on its revenues from its securities business.7 Broker-dealers that limit their business to certain specified activities or conduct their business outside of the United States are exempt from being members of SIPC.8 Consequently, these broker-dealers do not pay a SIPC assessment. However, they must file a 1 15 U.S.C. 78ccc(e)(2)(A). Securities Investor Protection Corporation, Release No. SIPA–173 (Oct. 28, 2015), 80 FR 68286 (Nov. 4, 2015). 3 See email from Paul W. Lameo to Michael A. Macchiaroli dated December 22, 2015. The comment requested clarification regarding a number of technical questions concerning the process for filing reports with SIPC. SIPC intends to issue Frequently Asked Questions to respond to those and other technical questions. 4 Under SIPA, to be final, rules proposed by SIPC must be approved by the Commission. See 15 U.S.C. 78ccc(e)(2). 5 See 15 U.S.C. 78ddd(c); SIPC Bylaws, Article 6. 6 See 15 U.S.C. 78ddd(c) and (d). 7 Form SIPC–7 provides that the broker-dealer may deduct from the end of fiscal year assessment the amount paid mid-year with the filing of the Form SIPC–6. 8 See 15 U.S.C. 78ccc(a)(2)(A). 2 See E:\FR\FM\17MRR1.SGM 17MRR1

Airworthiness Directives; Turbomeca S.A. Turboshaft Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are superseding airworthiness directive (AD) 2006-23-17 for 
certain Turbomeca S.A. Turmo IV A and IV C turboshaft engines. AD 2006-
23-17 required repetitive inspections of the centrifugal compressor 
intake wheel (inducer) blades for cracks and corrosion, replacement of 
parts that fail inspection, and replacement of the TU 197 standard 
centrifugal compressor. This AD requires the same inspections, but at 
revised intervals, adds the replacement of the TU 215 standard 
centrifugal compressor, and requires replacement of parts that fail 
inspection. This AD was prompted by a centrifugal compressor inducer 
blade loss. This AD was also prompted by a Turbomeca S.A. review of the 
engine service experience and their determination that more frequent 
borescope inspections (BSIs) are required on engines not modified to 
the TU 191, TU 197, or TU 224 standard. We are issuing this AD to 
prevent failure of the centrifugal compressor inducer, which could lead 
to an uncontained blade release, damage to the engine, and damage to 
the airplane.

DATES: This AD is effective April 21, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of April 21, 
2016.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2006-23-17, Amendment 39-14829 (71 FR 66664, 
November 16, 2006), (``AD 2006-23-17''). AD 2006-23-17 applied to the 
specified products. The NPRM published in the Federal Register on 
November 25, 2015 (80 FR 73681). The NPRM proposed to require the same 
inspections, but at revised intervals, add the replacement of the TU 
215 standard centrifugal compressor, and require replacement of parts 
that fail inspection.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (80 FR 73681, November 25, 
2015).

Conclusion

    We reviewed the available data and determined that air safety and 
the public interest require adopting this AD as proposed.

Related Service Information Under 1 CFR Part 51

    We reviewed Turbomeca S.A. Alert Mandatory Service Bulletin (MSB) 
No. A249 72 0100, Version H, dated May 21, 2015. The Alert MSB 
describes procedures for the inspection and replacement of the 
centrifugal compressor inducer blades. 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 36 engines installed on airplanes 
of U.S. registry. We estimate that two of these engines will require 
compressor replacement. We also estimate that about 40 hours per engine 
are required to comply with this AD. The average labor rate is $85 per 
hour. Parts cost about $40,000 per engine. Based on these figures, we 
estimate the cost of this AD on U.S. operators to be $202,400.

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

    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

2006-23-17, Amendment 39-14829 (71 FR 66664, November 16, 2006) 
(``2006-23-17''), and adding the following new AD:

2016-05-08 Turbomeca S.A.: Amendment 39-18426; Docket No. FAA-2006-
25970; Directorate Identifier 99-NE-12-AD.

(a) Effective Date

    This AD is effective April 21, 2016.

(b) Affected ADs

    This AD replaces AD 2006-23-17.

(c) Applicability

    This AD applies to Turbomeca S.A. Turmo IV A and IV C turboshaft 
engines.

(d) Unsafe Condition

    This AD was prompted by a centrifugal compressor inducer blade 
loss. We are issuing this AD to prevent failure of the centrifugal 
compressor inducer, which could lead to an uncontained blade 
release, damage to the engine, and damage to the airplane.

(e) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.
    (1) Remove the TU 197 and TU 215 standard centrifugal 
compressors and install the TU 224 standard centrifugal compressor, 
within 30 days after the effective date of this AD.
    (2) Perform initial and repetitive ultrasonic inspections (UIs) 
or eddy current inspections

(ECIs) of the centrifugal compressor (inducer). Use Accomplishment 
Instructions, paragraph 6.B.(1)(b) of Turbomeca S.A. Alert Mandatory 
Service Bulletin (MSB) No. A249 72 0100, Version H, dated May 21, 
2015 to do the inspections. Use Appendix 1 of Turbomeca S.A. Alert 
MSB No. A249 72 0100, Version H, dated May 21, 2015 for the schedule 
of inspections.
    (3) Perform initial and repetitive borescope inspections (BSIs) 
of the centrifugal compressor inducer. Use Accomplishment 
Instructions, paragraphs 6.B.(1)(a) of Turbomeca S.A. Alert MSB No. 
A249 72 0100, Version H, dated May 21, 2015 to do the inspections. 
Use Appendix 1 of Turbomeca S.A. Alert MSB No. A249 72 0100, Version 
H, dated May 21, 2015 for the schedule of inspections.
    (4) If, during any inspection required by paragraphs (e)(2) or 
(e)(3) of this AD, any crack, corrosion, or other damage is detected 
on the inducer, then before next flight, replace the centrifugal 
compressor.
    (5) Accomplishment of a UI or ECI of the centrifugal compressor 
inducer, required by paragraph (e)(2) of this AD, is acceptable in 
lieu of a BSI required by paragraph (e)(3) of this AD for that 
engine.
    (6) Replacement of a centrifugal compressor required by 
paragraph (e)(4) of this AD, does not constitute terminating action 
for the repetitive inspections required by paragraphs (e)(2) and 
(e)(3) of this AD.

(f) Credit for Previous Actions

    You may take credit for the inspections and corrective actions 
required by paragraphs (e)(2) and (e)(3) of this AD, if you 
performed the inspections and corrective actions before the 
effective date of this AD, using Turbomeca S.A. Alert MSB No. A249 
72 0100, Version G, or an earlier version.
