USDA is an equal opportunity provider, employer, and lender. implemented by Regulation Z of the Federal Reserve System, and with RESPA as implemented by Regulation X of the Department of Housing and Urban Development. In 2010, Congress signed into law the Dodd-Frank Wall Street Reform and Consumer Protection Act (Dodd-Frank Act). The Dodd-Frank Act directed the Consumer Financial Protection Bureau (CFPB) to integrate the mortgage loan disclosures under TILA and RESPA Sections 4 and 5. The CFPB’s TRID rule requires easier-to-use mortgage disclosure forms that clearly lay out the terms of a mortgage for a homebuyer; the rule consolidated the four disclosures required under TILA and RESPA into two forms: A Loan Estimate and a Closing Disclosure. With the TRID rule’s effective date of October 3, 2015 (80 FR 43911), which modified 12 CFR parts 1024 and 1026, 7 CFR part 1940, subpart I, has become functionally obsolete since it refers to outdated processes, forms, and governing bodies. Through this direct final action, this functionally obsolete regulation will be eliminated to avoid confusion and possible noncompliance on the part of Agency staff; and the RHS programs’ guidance will cite the TRID rule as the standard to follow. The TRID rule contains comprehensive instructions on its subject matter. By citing the CFPB’s requirements regarding mortgage disclosures in its guidance, it is the Agency’s objective to ensure that any future changes are immediately and accurately incorporated by reference. List of Subjects in 7 CFR Part 1940 Agriculture, Environmental protection, Flood plains, Grant programs—agriculture, Grant programs—housing and community development, Loan programs— agriculture, Loan programs—housing and community development, Low and moderate-income housing, Reporting and recordkeeping requirements, Rural areas, Truth in lending.

SUPPLEMENTARY INFORMATION: amozie on DSK30RV082PROD 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 Bombardier, Inc., Model CL–600–2B19 (Regional Jet Series 100 & 440), Model CL–600–2C10 (Regional Jet Series 700, 701, & 702), Model CL–600– 2D15 (Regional Jet Series 705), and Model CL–600–2D24 (Regional Jet Series 900) airplanes. The NPRM published in the Federal Register on May 31, 2017 (82 FR 24897) (‘‘the NPRM’’). The NPRM was prompted by development of a modification to prevent uncommanded rudder movement during flight. The NPRM proposed to require modifying the wiring harness of the yaw damper control system. We are issuing this AD to prevent uncommanded rudder movement and consequent loss of the ability to control the airplane. Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian Airworthiness Directive CF–2017–06, effective February 14, 2017 (referred to after this as the Mandatory Continuing VerDate Sep<11>2014 16:24 Mar 22, 2018 Jkt 244001 Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for all Bombardier, Inc., Model CL–600– 2B19 (Regional Jet Series 100 & 440), Model CL–600–2C10 (Regional Jet Series 700, 701, & 702), Model CL–600– 2D15 (Regional Jet Series 705), and Model CL–600–2D24 (Regional Jet Series 900) airplanes. The MCAI states: [Canadian] AD CF–2013–13 was issued on 28 May 2013 [related to FAA AD 2013–14– 11, Amendment 39–17516 (78 FR 44871, July 25, 2013) (‘‘AD 2013–14–11’’)] to mandate the introduction of an emergency procedure to the Aeroplane Flight Manual to address the uncommanded rudder movement. Since the original issue of [Canadian] AD CF–2013–13, Bombardier Aerospace has developed a wiring modification for the yaw damper control system to prevent uncommanded movement of the rudder [and consequent loss of the ability to control the airplane]. This [Canadian] AD mandates the wiring modification for the yaw damper control system * * *. You may examine the MCAI in the AD docket on the internet at http:// www.regulations.gov by searching for and locating Docket No. FAA–20**– ****. Comments We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the NPRM and the FAA’s response to each comment. Support for the NPRM The Air Line Pilots Association, International (ALPA), agreed with the intent of the NPRM. Request To Clarify Credit for Certain Service Information SkyWest Airlines and Ahmad Lababidi asked that we revise paragraph (h) of the proposed AD to clarify the credit language for accomplishing the engineering orders in conjunction with the referenced service information. Ahmad Lababidi stated that Service Non-Incorporated Engineering Order (SNIEO) K601R50211 S02, dated October 31, 2014, was issued for certain airplane configurations where the wire connector was changed from pin type to socket type. The commenters added that SNIEOs K601R50211 S03, dated April 21, 2015, and S04, dated April 24, 2015, were issued to clarify certain splicing, capping, and stowing locations, and to reduce the work hours for accomplishing the actions specified in the service bulletin. The commenters added that it is not necessary to do the engineering orders in conjunction with the referenced service information. SkyWest reported accomplishing the PO 00000 Frm 00004 Fmt 4700 Sfmt 4700 modification on some airplanes using only the applicable service bulletin without any reference to the SNIEOs specified in paragraph (h) of the proposed AD. We agree with the commenters’ requests for the reasons provided. We have revised paragraphs (h)(1)(i) and (h)(1)(ii) of this AD to remove reference to the SNIEOs, which are not required to be used in conjunction with the referenced service information. Request To Revise Parts Installation Limitations Paragraph Air Wisconsin asked that we revise paragraph (i) of the proposed AD (Parts Installation Limitations) to exclude parts on which the actions in the referenced service information have been done. We acknowledge the commenter’s request. However, paragraph (i) of this AD already prohibits installation of a yaw damper actuator . . . ‘‘unless it has been modified in accordance with the applicable service information specified in table 1 to paragraph (g) of this AD.’’ Since existing language meets the intent of the commenter’s request, 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 with the changes described previously, and 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 Bombardier has issued Service Bulletin 601R–22–017, Revision C, dated May 11, 2016; and Service Bulletin 670BA–22–007, Revision A, dated February 16, 2016. This service information describes procedures for modifying the wiring harness of the yaw damper control system. These documents are distinct since they apply to different airplane models. 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. E:\FR\FM\23MRR1.SGM 23MRR1 Federal Register / Vol. 83, No. 57 / Friday, March 23, 2018 / Rules and Regulations Costs of Compliance We estimate that this AD affects 1,006 airplanes of U.S. registry. 12661 We estimate the following costs to comply with this AD: ESTIMATED COSTS Action Labor cost Parts cost Cost per product Wiring modification ............ 5 work-hours × $85 per hour = $425 ........................... Up to $39 .... Up to $464 .. According to the manufacturer, 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 for affected individuals. As a result, we have included all costs in our cost estimate. Authority for This Rulemaking amozie on DSK30RV082PROD with RULES 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. This AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to transport category VerDate Sep<11>2014 16:24 Mar 22, 2018 Jkt 244001 airplanes to the Director of the System Oversight Division. 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 Bombardier, Inc., Model 
CL-600-2B19 (Regional Jet Series 100 & 440), Model CL-600-2C10 
(Regional Jet Series 700, 701, & 702), Model CL-600-2D15 (Regional Jet 
Series 705), and Model CL-600-2D24 (Regional Jet Series 900) airplanes. 
The NPRM published in the Federal Register on May 31, 2017 (82 FR 
24897) (``the NPRM''). The NPRM was prompted by development of a 
modification to prevent uncommanded rudder movement during flight. The 
NPRM proposed to require modifying the wiring harness of the yaw damper 
control system. We are issuing this AD to prevent uncommanded rudder 
movement and consequent loss of the ability to control the airplane.
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2017-06, effective February 14, 2017 (referred to after this as the 
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to 
correct an unsafe condition for all Bombardier, Inc., Model CL-600-2B19 
(Regional Jet Series 100 & 440), Model CL-600-2C10 (Regional Jet Series 
700, 701, & 702), Model CL-600-2D15 (Regional Jet Series 705), and 
Model CL-600-2D24 (Regional Jet Series 900) airplanes. The MCAI states:

    [Canadian] AD CF-2013-13 was issued on 28 May 2013 [related to 
FAA AD 2013-14-11, Amendment 39-17516 (78 FR 44871, July 25, 2013) 
(``AD 2013-14-11'')] to mandate the introduction of an emergency 
procedure to the Aeroplane Flight Manual to address the uncommanded 
rudder movement.
    Since the original issue of [Canadian] AD CF-2013-13, Bombardier 
Aerospace has developed a wiring modification for the yaw damper 
control system to prevent uncommanded movement of the rudder [and 
consequent loss of the ability to control the airplane].
    This [Canadian] AD mandates the wiring modification for the yaw 
damper control system * * *.

    You may examine the MCAI in the AD docket on the internet at http://www.regulations.gov by searching for and locating Docket No. FAA-20**-
****.

Comments

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

Support for the NPRM

    The Air Line Pilots Association, International (ALPA), agreed with 
the intent of the NPRM.

Request To Clarify Credit for Certain Service Information

    SkyWest Airlines and Ahmad Lababidi asked that we revise paragraph 
(h) of the proposed AD to clarify the credit language for accomplishing 
the engineering orders in conjunction with the referenced service 
information. Ahmad Lababidi stated that Service Non-Incorporated 
Engineering Order (SNIEO) K601R50211 S02, dated October 31, 2014, was 
issued for certain airplane configurations where the wire connector was 
changed from pin type to socket type. The commenters added that SNIEOs 
K601R50211 S03, dated April 21, 2015, and S04, dated April 24, 2015, 
were issued to clarify certain splicing, capping, and stowing 
locations, and to reduce the work hours for accomplishing the actions 
specified in the service bulletin. The commenters added that it is not 
necessary to do the engineering orders in conjunction with the 
referenced service information. SkyWest reported accomplishing the 
modification on some airplanes using only the applicable service 
bulletin without any reference to the SNIEOs specified in paragraph (h) 
of the proposed AD.
    We agree with the commenters' requests for the reasons provided. We 
have revised paragraphs (h)(1)(i) and (h)(1)(ii) of this AD to remove 
reference to the SNIEOs, which are not required to be used in 
conjunction with the referenced service information.

Request To Revise Parts Installation Limitations Paragraph

    Air Wisconsin asked that we revise paragraph (i) of the proposed AD 
(Parts Installation Limitations) to exclude parts on which the actions 
in the referenced service information have been done.
    We acknowledge the commenter's request. However, paragraph (i) of 
this AD already prohibits installation of a yaw damper actuator . . . 
``unless it has been modified in accordance with the applicable service 
information specified in table 1 to paragraph (g) of this AD.'' Since 
existing language meets the intent of the commenter's request, 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 with the changes described previously, and 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

    Bombardier has issued Service Bulletin 601R-22-017, Revision C, 
dated May 11, 2016; and Service Bulletin 670BA-22-007, Revision A, 
dated February 16, 2016. This service information describes procedures 
for modifying the wiring harness of the yaw damper control system. 
These documents are distinct since they apply to different airplane 
models. 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 1,006 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                                  Cost on U.S.
             Action                    Labor cost            Parts cost      Cost per product      operators
----------------------------------------------------------------------------------------------------------------
Wiring modification............  5 work-hours x $85 per  Up to $39........  Up to $464.......  Up to $466,784.
                                  hour = $425.
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, 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 for affected 
individuals. As a result, 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 products identified in this 
rulemaking action.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to transport category airplanes to 
the Director of the System Oversight Division.

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.
