SUPPLEMENTARY INFORMATION: VerDate Sep<11>2014 16:08 Mar 14, 2018 Jkt 244001 Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Bombardier, Inc., Model CL–600–2B16 (CL–604 Variant) airplanes. The NPRM published in the Federal Register on June 27, 2017 (82 FR 29014) (‘‘the NPRM’’). The NPRM was prompted by reports of in-flight uncommanded rudder movements on airplanes with an installation similar to the installation on certain Model CL– 600–2B16 (CL–604 Variant) airplanes. The NPRM proposed to require modification of the wiring for the yaw damper control system. We are issuing this AD to prevent in-flight uncommanded rudder movements, which could lead to structural failure and subsequent loss of the airplane. Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian Airworthiness Directive CF–2016–38, effective December 12, 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– 600–2B16 (CL–604 Variant) airplanes. The MCAI states: The [Canadian] AD CF–2013–22 [which corresponds to FAA AD 2014–16–06, Amendment 39–17930 (79 FR 48972, August 19, 2014)] was issued on 12 August 2013 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–2013–22, Bombardier Aerospace has developed a wiring modification for the yaw damper control system to prevent uncommanded movement of the rudder. This [Canadian] AD mandates the incorporation of Service Bulletins (SB) 604– 22–007 and 605–22–002 * * * *. This AD requires modification of the wiring for the yaw damper control system. 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–2017– 0626. Comments We gave the public the opportunity to participate in developing this AD. The following presents the comment received on the NPRM and the FAA’s response to that comment. Request To Clarify Airplane Model That Experienced In-Flight Uncommanded Rudder Movement Bombardier, Inc., requested that the Reason section (paragraph (e) of the proposed AD) be revised to clarify that PO 00000 Frm 00011 Fmt 4700 Sfmt 4700 11405 the in-flight uncommanded rudder movements occurred on airplanes with an installation similar to the installation on certain Model CL–600–2B16 airplanes and did not occur on Model CL–600–2B16 airplanes. Bombardier, Inc., stated that it is not aware of any inflight uncommanded rudder movements that were experienced by operators of Model CL–600–2B16 airplanes, but as written, the Reason section of the NPRM implied that these events occurred on Model CL–600–2B16 airplanes. For the reason provided by the commenter, we agree to revise the SUMMARY and Discussion sections of this final rule and paragraph (e) of this AD to clarify that the in-flight uncommanded rudder movements occurred on airplanes with an installation similar to the installation on certain Model CL–600–2B16 airplanes. We have issued AD 2013–14–11, Amendment 39–17516 (78 FR 44871, July 25, 2013) to address the same unsafe condition for Model CL–600– 2B19 (Regional Jet Series 100 & 440) airplanes, Model CL–600–2C10 (Regional Jet Series 700, 701, & 702) airplanes, Model CL–600–2D15 (Regional Jet Series 705) airplanes, and Model CL–600–2D24 (Regional Jet Series 900) airplanes. Conclusion We reviewed the relevant data, considered the comment 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, Inc., issued Service Bulletin 604–22–007, Revision 01, dated July 25, 2016; and Service Bulletin 605– 22–002, Revision 01, dated July 25, 2016. This service information describes procedures for modifying the wiring harness for the yaw damper control system. These documents are distinct since they apply to different airplane configurations. This service information is reasonably available because the interested parties have access to it through their normal course of business E:\FR\FM\15MRR1.SGM 15MRR1 11406 Federal Register / Vol. 83, No. 51 / Thursday, March 15, 2018 / Rules and Regulations Costs of Compliance or by the means identified in the ADDRESSES section. We estimate that this AD affects 120 airplanes of U.S. registry. We estimate the following costs to comply with this AD: ESTIMATED COSTS Action Labor cost Parts cost Cost per product Modification ................ 50 work-hours × $85 per hour = $4,250 ........ Up to $478 ................. Up to $4,728 .............. 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. sradovich on DSK3GMQ082PROD with RULES 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. VerDate Sep<11>2014 16:08 Mar 14, 2018 Jkt 244001 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 certain Bombardier, Inc., 
Model CL-600-2B16 (CL-604 Variant) airplanes. The NPRM published in the 
Federal Register on June 27, 2017 (82 FR 29014) (``the NPRM''). The 
NPRM was prompted by reports of in-flight uncommanded rudder movements 
on airplanes with an installation similar to the installation on 
certain Model CL-600-2B16 (CL-604 Variant) airplanes. The NPRM proposed 
to require modification of the wiring for the yaw damper control 
system. We are issuing this AD to prevent in-flight uncommanded rudder 
movements, which could lead to structural failure and subsequent loss 
of the airplane.
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2016-38, effective December 12, 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-
2B16 (CL-604 Variant) airplanes. The MCAI states:

    The [Canadian] AD CF-2013-22 [which corresponds to FAA AD 2014-
16-06, Amendment 39-17930 (79 FR 48972, August 19, 2014)] was issued 
on 12 August 2013 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-2013-22, Bombardier 
Aerospace has developed a wiring modification for the yaw damper 
control system to prevent uncommanded movement of the rudder.
    This [Canadian] AD mandates the incorporation of Service 
Bulletins (SB) 604-22-007 and 605-22-002 * * * *.

    This AD requires modification of the wiring for the yaw damper 
control system. 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-2017-0626.

Comments

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

Request To Clarify Airplane Model That Experienced In-Flight 
Uncommanded Rudder Movement

    Bombardier, Inc., requested that the Reason section (paragraph (e) 
of the proposed AD) be revised to clarify that the in-flight 
uncommanded rudder movements occurred on airplanes with an installation 
similar to the installation on certain Model CL-600-2B16 airplanes and 
did not occur on Model CL-600-2B16 airplanes. Bombardier, Inc., stated 
that it is not aware of any in-flight uncommanded rudder movements that 
were experienced by operators of Model CL-600-2B16 airplanes, but as 
written, the Reason section of the NPRM implied that these events 
occurred on Model CL-600-2B16 airplanes.
    For the reason provided by the commenter, we agree to revise the 
SUMMARY and Discussion sections of this final rule and paragraph (e) of 
this AD to clarify that the in-flight uncommanded rudder movements 
occurred on airplanes with an installation similar to the installation 
on certain Model CL-600-2B16 airplanes. We have issued AD 2013-14-11, 
Amendment 39-17516 (78 FR 44871, July 25, 2013) to address the same 
unsafe condition for Model CL-600-2B19 (Regional Jet Series 100 & 440) 
airplanes, Model CL-600-2C10 (Regional Jet Series 700, 701, & 702) 
airplanes, Model CL-600-2D15 (Regional Jet Series 705) airplanes, and 
Model CL-600-2D24 (Regional Jet Series 900) airplanes.

Conclusion

    We reviewed the relevant data, considered the comment 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, Inc., issued Service Bulletin 604-22-007, Revision 01, 
dated July 25, 2016; and Service Bulletin 605-22-002, Revision 01, 
dated July 25, 2016. This service information describes procedures for 
modifying the wiring harness for the yaw damper control system. These 
documents are distinct since they apply to different airplane 
configurations. This service information is reasonably available 
because the interested parties have access to it through their normal 
course of business

[[Page 11406]]

or by the means identified in the ADDRESSES section.

Costs of Compliance

    We estimate that this AD affects 120 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
----------------------------------------------------------------------------------------------------------------
Modification....................  50 work-hours x     Up to $478........  Up to $4,728......  Up to $567,360.
                                   $85 per hour =
                                   $4,250.
----------------------------------------------------------------------------------------------------------------

    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.
