SUPPLEMENTARY INFORMATION: Discussion Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian AD CF–2018–29, dated November 2, 2018 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for certain Bombardier, Inc., Model CL–600–2B19 (Regional Jet Series 100 & 440), CL–600–2C10 (Regional Jet Series 700, 701 & 702), CL– 600–2D15 (Regional Jet Series 705), CL– 600–2D24 (Regional Jet Series 900), and CL–600–2E25 (Regional Jet Series 1000) airplanes. 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–2019–0436. The FAA 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–600–2B19 (Regional Jet Series 100 & 440), CL–600–2C10 (Regional Jet Series 700, 701 & 702), CL–600–2D15 (Regional Jet Series 705), CL–600–2D24 (Regional Jet Series 900), and CL–600– 2E25 (Regional Jet Series 1000) airplanes. The NPRM published in the Federal Register on June 21, 2019 (84 FR 29108). The NPRM was prompted by reports of PCU rod end fractures due to pitting corrosion. The NPRM proposed to require revising the existing maintenance or inspection program, as applicable, to incorporate new maintenance tasks. The NPRM also proposed to require detailed inspections of the elevator PCU rod ends and VerDate Sep<11>2014 16:14 Nov 08, 2019 Jkt 250001 applicable corrective actions, and prohibit using certain aircraft maintenance manual tasks. The FAA is issuing this AD to address PCU rod end fractures due to pitting corrosion, which, if not detected and corrected, could lead to a disconnect between the PCU and the control surface, resulting in potential loss of the control surface function or inadequate flutter suppression. See the MCAI for additional background information. Comments The FAA gave the public the opportunity to participate in developing this final rule. The FAA has considered the comment received. The commenter, Patrick Imperatrice, stated that he supports the NPRM. Conclusion The FAA reviewed the relevant data, considered the comment received, and determined that air safety and the public interest require adopting this final rule as proposed, except for minor editorial changes. The FAA has determined that these minor changes: • Are consistent with the intent that was proposed in the NPRM for addressing the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM. Related Service Information Under 1 CFR Part 51 Bombardier has issued the following service information. Bombardier Service Bulletin 670BA– 27–074, dated June 22, 2017.

E:\FR\FM\12NOR1.SGM 12NOR1 60904 Federal Register / Vol. 84, No. 218 / Tuesday, November 12, 2019 / Rules and Regulations Costs of Compliance The FAA estimates the following costs to comply with this AD: The FAA estimates that this AD affects 1,008 airplanes of U.S. registry. ESTIMATED COSTS FOR REQUIRED ACTIONS * Labor cost Cost per product Parts cost 9 work-hours × $85 per hour = $765 .......................................................................................... $0 $765 Cost on U.S. operators $771,120 * Table does not include estimated costs for revising the maintenance or inspection program. The FAA has determined that revising the existing maintenance or inspection program takes an average of 90 workhours per operator, although the FAA recognizes that this number may vary from operator to operator. In the past, the FAA has estimated that this action takes 1 work-hour per airplane. Since operators incorporate maintenance or inspection program changes for their affected fleet(s), the FAA has determined that a per-operator estimate is more accurate than a per-airplane estimate. Therefore, the FAA estimates the total cost per operator to be $7,650 (90 work-hours × $85 per work-hour). The FAA has received no definitive data that would enable the agency to provide cost estimates for the oncondition actions specified in this AD. 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. The FAA is 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 16:14 Nov 08, 2019 Jkt 250001 airplanes and associated appliances to the Director of the System Oversight Division. 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) Will not affect intrastate aviation in Alaska, and (3) 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 AD CF-2018-29, dated November 
2, 2018 (referred to after this as the Mandatory Continuing 
Airworthiness Information, or ``the MCAI''), to correct an unsafe 
condition for certain Bombardier, Inc., Model CL-600-2B19 (Regional Jet 
Series 100 & 440), CL-600-2C10 (Regional Jet Series 700, 701 & 702), 
CL-600-2D15 (Regional Jet Series 705), CL-600-2D24 (Regional Jet Series 
900), and CL-600-2E25 (Regional Jet Series 1000) airplanes. 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-2019-
0436.
    The FAA 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-600-2B19 (Regional Jet Series 100 & 440), CL-600-2C10 
(Regional Jet Series 700, 701 & 702), CL-600-2D15 (Regional Jet Series 
705), CL-600-2D24 (Regional Jet Series 900), and CL-600-2E25 (Regional 
Jet Series 1000) airplanes. The NPRM published in the Federal Register 
on June 21, 2019 (84 FR 29108). The NPRM was prompted by reports of PCU 
rod end fractures due to pitting corrosion. The NPRM proposed to 
require revising the existing maintenance or inspection program, as 
applicable, to incorporate new maintenance tasks. The NPRM also 
proposed to require detailed inspections of the elevator PCU rod ends 
and applicable corrective actions, and prohibit using certain aircraft 
maintenance manual tasks.
    The FAA is issuing this AD to address PCU rod end fractures due to 
pitting corrosion, which, if not detected and corrected, could lead to 
a disconnect between the PCU and the control surface, resulting in 
potential loss of the control surface function or inadequate flutter 
suppression. See the MCAI for additional background information.

Comments

    The FAA gave the public the opportunity to participate in 
developing this final rule. The FAA has considered the comment 
received. The commenter, Patrick Imperatrice, stated that he supports 
the NPRM.

Conclusion

    The FAA reviewed the relevant data, considered the comment 
received, and determined that air safety and the public interest 
require adopting this final rule as proposed, except for minor 
editorial changes. The FAA has determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for addressing the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Costs of Compliance

    The FAA estimates that this AD affects 1,008 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

                                     Estimated Costs for Required Actions *
----------------------------------------------------------------------------------------------------------------
                                                                                     Cost per      Cost on  U.S.
                           Labor cost                               Parts cost        product        operators
----------------------------------------------------------------------------------------------------------------
9 work-hours x $85 per hour = $765..............................              $0            $765        $771,120
----------------------------------------------------------------------------------------------------------------
* Table does not include estimated costs for revising the maintenance or inspection program.

    The FAA has determined that revising the existing maintenance or 
inspection program takes an average of 90 work-hours per operator, 
although the FAA recognizes that this number may vary from operator to 
operator. In the past, the FAA has estimated that this action takes 1 
work-hour per airplane. Since operators incorporate maintenance or 
inspection program changes for their affected fleet(s), the FAA has 
determined that a per-operator estimate is more accurate than a per-
airplane estimate. Therefore, the FAA estimates the total cost per 
operator to be $7,650 (90 work-hours x $85 per work-hour).
    The FAA has received no definitive data that would enable the 
agency to provide cost estimates for the on-condition actions specified 
in this AD.

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.
    The FAA is 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 and 
associated appliances to the Director of the System Oversight Division.

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) Will not affect intrastate aviation in Alaska, and
    (3) 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.
