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) airplanes; 
Model CL-600-2D15 (Regional Jet Series 705) airplanes; Model CL-600-
2D24 (Regional Jet Series 900) airplanes; and Model CL-600-2E25 
(Regional Jet Series 1000) airplanes. The NPRM published in the Federal 
Register on July 6, 2018 (83 FR 31504). The NPRM was prompted by 
reports of damage to the protective coating and corrosion on the 
piston/axle of the MLG, caused by friction between the inboard axle 
sleeve and the axle thrust face. The NPRM proposed to require revising 
the maintenance or inspection program, as applicable, to incorporate a 
detailed inspection of the MLG piston/axle for damage to the protective 
coating and for corrosion.
    We are issuing this AD to address damage to the protective coating 
and corrosion found on the piston/axle of the MLG, caused by friction 
between the inboard axle sleeve and the axle thrust face, which could 
cause the axle to separate from the piston/axle, and ultimately lead to 
collapse of the landing gear during ground maneuvers or upon landing.
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian AD CF-2017-38, dated December 
20, 2017 (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) airplanes; Model CL-600-2D15 (Regional Jet 
Series 705) airplanes; Model CL-600-2D24 (Regional Jet Series 900) 
airplanes; and Model CL-600-2E25 (Regional Jet Series 1000) airplanes. 
The MCAI states:

    There have been reports of damage to the protective coating and/
or corrosion on the piston/axle of the Main Landing Gear (MLG). The 
damage to the protective coating was caused by friction between the 
inboard axle sleeve and the axle thrust face. If not corrected, this 
condition can cause the axle to separate from the piston/axle [and 
consequent collapse of the landing gear during ground maneuvers or 
upon landing].
    This [Canadian] AD mandates the incorporation of a new 
maintenance task in order to perform a [detailed] visual inspection 
of the piston/axle of the MLG to prevent the axle separation from 
the piston/axle.

    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-2018-
0551.

Comments

    We gave the public the opportunity to participate in developing 
this final rule. 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 and Endeavor Air 
stated their support for the proposed AD.

Request To Refer to Certain Revised Service Information

    Endeavor Air noted that Bombardier, Inc. has issued certain revised 
service information and requested that the proposed AD be updated to 
reference the revised service information.
    We agree with the commenter's request. We have determined the 
revised service information should be referenced in regards to 
calculating the time since piston/axle entry into service, since 
operators might have done the latest inspection, restoration, or repair 
using the revised service information. We have updated paragraph (h) of 
this AD to refer to the revised service information and reorganized 
paragraph (h) of this AD for consistency.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
this final rule 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 addressing 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 final 
rule.

Related Service Information Under 1 CFR Part 51

    Bombardier, Inc. has issued CRJ Series Regional Jet Temporary 
Revision (TR) MRB-0059, dated March 20, 2015. The service information 
describes an airworthiness limitation task for a detailed inspection 
for damage to the protective coating and for corrosion on the piston/
axle of the MLG. 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 530 airplanes of U.S. registry. We 
estimate the following costs to comply with this AD:
    We have determined that revising the maintenance or inspection 
program takes an average of 90 work-hours per operator, although we 
recognize that this number may vary from operator to operator. In the 
past, we have estimated that this action takes 1 work-hour per 
airplane. Since operators incorporate maintenance or inspection program 
changes for their affected fleet(s), we have determined that a per-
operator estimate is more accurate than a per-airplane estimate. 
Therefore, we estimate the total cost per operator to be $7,650 (90 
work-hours x $85 per work-hour).

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

[[Page 55608]]

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 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) 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.
