For the purpose of this paragraph (b)(2), ‘‘subsidiary company’’ means a company in which the financed passive business either: (i) Directly owns, or will own as a result of the Financing, at least 50 percent of the outstanding voting securities; or (ii) Indirectly owns, or will own as a result of the Financing, at least 50 percent of the outstanding voting securities (by directly owning the outstanding voting securities of another passive Small Business that is the direct owner of the outstanding voting securities of the subsidiary company). (3) Exception for certain Partnership Licensees. If you are a Partnership Licensee, you may form one or more blocker entities in accordance with this paragraph (b)(3). For the purposes of this paragraph, a ‘‘blocker entity’’ means a corporation or a limited liability company that elects to be taxed as a corporation for Federal income tax purposes. The sole purpose of a blocker entity must be to provide Financing to one or more eligible, unincorporated Small Businesses. You may form such blocker entities only if a direct Financing to such Small Businesses would cause any of your investors to incur ‘‘unrelated business taxable income’’ under section 511 of the Internal Revenue Code (26 U.S.C. 511) or to incur ‘‘effectively connected income’’ to foreign investors under sections 871 and 882 of the Internal Revenue Code (26 U.S.C. 871 and 882). Your ownership and investment of funds in such blocker entities will not constitute a violation of § 107.730(a). For each passive business financed under this section 107.720(b)(3), you must provide a certification to SBA as required under § 107.610(g). A blocker entity formed under this paragraph may provide Financing: (i) Directly to one or more eligible non-passive Small Businesses; or (ii) Directly to a passive Small Business that passes substantially all the proceeds directly to (or uses substantially all the proceeds to acquire) one or more eligible non-passive Small Businesses in which the passive Small Business directly owns, or will own as a result of the Financing, at least 50% of the outstanding voting securities. (4) Additional conditions for permitted passive business financings. Financings permitted under paragraphs (b)(2) or (3) of this section must meet all of the following conditions: (i) For the purposes of this paragraph (b), ‘‘substantially all’’ means at least 99 percent of the Financing proceeds after deduction of actual application fees, closing fees, and expense VerDate Sep<11>2014 15:59 Aug 17, 2017 Jkt 241001 reimbursements, which may not exceed those permitted by § 107.860. (ii) If you and/or your Associate charge fees permitted by § 107.860 and/ or § 107.900, the total amount of such fees charged to all passive and nonpassive businesses that are part of the same Financing may not exceed the fees that would have been permitted if the Financing had been provided directly to a non-passive Small Business. Any such fees received by your Associate must be paid to you in cash within 30 days of the receipt of such fees. (iii) For the purposes of this part 107, each passive and non-passive business included in the Financing is a Portfolio Concern. The terms of the financing must provide SBA with access to Portfolio Concern information in compliance with this part 107, including without limitation §§ 107.600 and 107.620. * * * * * § 107.1100 [Amended] 8.

SUPPLEMENTARY INFORMATION: Discussion Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian Airworthiness Directive CF–2016–35, dated November 16, 2016 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for certain Bombardier, Inc., Model CL– 600–2E25 (Regional Jet Series 1000) airplanes. The MCAI states: It is possible for the shrouds of the High Pressure (HP) bleed air ducts located in the main wheel wells and overwing areas to deteriorate and consequently, their maximum permitted leakage rate could be exceeded. If a significant bleed air leak is not sensed by the detection system, hot air impingement may cause damage to the adjacent structure and system components or create a fire hazard. This [Canadian] AD is issued to mandate a modification of the bleed-air duct and detection system, as well as a revision of the Airworthiness Limitation tasks to correspond with this modification. mstockstill on DSK30JT082PROD with RULES You may examine the MCAI on the Internet at https://www.regulations.gov by searching for and locating Docket No. FAA–2017–0699. Related Service Information Under 1 CFR Part 51 Bombardier, Inc. has issued Bombardier Service Bulletin 670BA–36– 022, Revision B, dated December 20, 2016. The service information describes modifying the bleed-air duct and detection system.

FAA’s Determination and Requirements of This AD This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are issuing this AD because we evaluated all pertinent information and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design. This AD requires revisions to certain operator maintenance documents to include new actions (e.g., inspections). Compliance with these actions is required by 14 CFR 91.403(c). For airplanes that have been previously modified, altered, or repaired in the areas addressed by this AD, the operator may not be able to accomplish the actions described in the revisions. In this situation, to comply with 14 CFR 91.403(c), the operator must request approval for an alternative method of compliance according to paragraph (k)(1) of this AD. The request should include a description of changes to the required inspections that will ensure the continued operational safety of the airplane. PO 00000 Frm 00008 Fmt 4700 Sfmt 4700 FAA’s Determination of the Effective Date Since there are currently no domestic operators of this product, notice and opportunity for public comment before issuing this AD are unnecessary. Comments Invited This AD is a final rule that involves requirements affecting flight safety, and we did not precede it by notice and opportunity for public comment. We invite you to send any written relevant data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include ‘‘Docket No. FAA–2017–0699; Directorate Identifier 2017–NM–004– AD’’ at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this AD based on those comments. We will post all comments we receive, without change, to https:// www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this AD. Costs of Compliance We estimate that this AD affects 0 airplanes of U.S. registry. We also estimate that it will take about 91 work-hours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Required parts cost are not available. Based on these figures, we estimate the cost of this AD on U.S. operators to be $0, or $7,735 per product. 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 E:\FR\FM\18AUR1.SGM 18AUR1 39343 Federal Register / Vol. 82, No. 159 / Friday, August 18, 2017 / Rules and Regulations products identified in this rulemaking action. Regulatory Findings (f) Compliance PART 39—AIRWORTHINESS DIRECTIVES ■ 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.

SUPPLEMENTARY INFORMATION:

Discussion

Transport Canada Civil Aviation (TCCA), which is the aviation

authority for Canada, has issued Canadian Airworthiness Directive CF-

2016-35, dated November 16, 2016 (referred to after this as the

Mandatory Continuing Airworthiness Information, or ``the MCAI''), to

correct an unsafe condition for certain Bombardier, Inc., Model CL-600-

2E25 (Regional Jet Series 1000) airplanes. The MCAI states:

It is possible for the shrouds of the High Pressure (HP) bleed

air ducts located in the main wheel wells and overwing areas to

deteriorate and consequently, their maximum permitted leakage rate

could be exceeded. If a significant bleed air leak is not sensed by

the detection system, hot air impingement may cause damage to the

adjacent structure and system components or create a fire hazard.

This [Canadian] AD is issued to mandate a modification of the

bleed-air duct and detection system, as well as a revision of the

Airworthiness Limitation tasks to correspond with this modification.

You may examine the MCAI on the Internet at https://www.regulations.gov by searching for and locating Docket No. FAA-2017-

0699.
