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-600-2C10 (Regional Jet Series 700, 701, & 702), Model CL-600-
2D15 (Regional Jet Series 705), Model CL-600-2D24 (Regional Jet Series 
900), and Model CL-600-2E25 (Regional Jet Series 1000). The NPRM 
published in the Federal Register on June 21, 2017 (82 FR 28266) (``the 
NPRM''). The NPRM was prompted by a report indicating that a number of 
RBG wheels installed in the HSTA were manufactured using an incorrect 
material specification. The NPRM proposed to require replacement of the 
affected RBG wheels. We are

[[Page 51336]]

issuing this AD to prevent premature wear-out of the teeth of the RBG 
wheels, which could cause difficulties in maneuvering the airplane.
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2016-22, dated June 24, 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-600-2C10 
(Regional Jet Series 700, 701, & 702), Model CL-600-2D15 (Regional Jet 
Series 705), Model CL-600-2D24 (Regional Jet Series 900), and Model CL-
600-2E25 (Regional Jet Series 1000) airplanes. The MCAI states:

    An inspection by the vendor revealed that a number of Rubber 
Bull Gear (RBG) Wheels installed in the Horizontal Stabilizer Trim 
Actuator (HSTA) of the CL-600-2C10, CL-600-2D15, CL-600-2D24 and CL-
600-2E25 aeroplanes were manufactured from the incorrect material 
specification. The use of the incorrect material specification has a 
direct impact on the RBG Wheels life limit. The teeth of these non-
conforming RBG Wheels may experience premature wear out and if not 
corrected, this condition could result in difficulties in 
maneuvering the aeroplane.
    This [Canadian] AD mandates replacement of the RBGs whose wheels 
have been made using an incorrect material specification.

    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-2017-
0562.

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.

Request To Revise Compliance Times

    Air Line Pilots Association, International (ALPA) requested that we 
review and revise the compliance times specified in the proposed AD to 
reflect flight hours rather than flight cycles, and to align the times 
with a previous AD, AD 2011-12-06, Amendment 39-16713 (76 FR 33982, 
June 10, 2011) (``AD 2011-12-06''). The commenter asserted that the 
compliance times in AD 2011-12-06 were more conservative than what is 
written in the proposed AD, and that for a component with a known 
material defect that is continuously used throughout the duration of 
any given flight, flight hours rather than flight cycles would be a 
more appropriate metric to measure compliance time.
    We disagree with the commenter's proposed change. We reviewed 
TCCA's evaluation of the compliance times, and determined that they are 
appropriate to mitigate the unsafe condition. We have not received any 
data to demonstrate otherwise. In addition, the compliance times in AD 
2011-12-06 are also based on flight cycles instead of flight hours. 
Therefore, have not changed this AD in this regard.

Conclusion

    We reviewed the relevant data, considered the comment received, and 
determined that air safety and the public interest require adopting 
this AD as proposed, except for 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.

Related Service Information Under 1 CFR Part 51

    We reviewed Bombardier Service Bulletin 670BA-27-072, Revision A, 
dated October 26, 2016. This service information describes procedures 
for identification of affected HSTAs, and replacement if necessary. 
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 544 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------

                                 $85 per hour =
                                 $1,700.
----------------------------------------------------------------------------------------------------------------
\1\ We have received no definitive data that would enable us to provide cost estimates for the parts cost
  specified in this AD.

    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;

[[Page 51337]]

    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.
