Airworthiness Directives; Bombardier, Inc., Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

Bombardier, Inc., Model DHC-8-102, -103, -106, -201, -202, -301, -311,

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 DHC-8-102, -103, -106, -201, -202, -301, -311, and -315 
airplanes. The NPRM published in the Federal Register on May 2, 2017 
(82 FR 20453) (``the NPRM''). The NPRM was prompted by reports of 
undamped MLG extension in-service. The NPRM proposed to require 
replacement of the MLG retraction actuator rod-ends on both MLG 
assemblies. We are issuing this AD to prevent MLG undamped extensions, 
which could result in MLG structural failure, resulting in an unsafe 
asymmetric landing gear configuration.
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2016-36, dated November 22, 2016 (referred to after this as the 
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to 
correct an unsafe condition

[[Page 35635]]

for certain Bombardier, Inc., Model DHC-8-102, -103, -106, -201, -202, 
-301, -311, and -315 airplanes. The MCAI states:

    Two cases of undamped main landing gear (MLG) extension were 
reported in-service. Investigation determined that the MLG 
retraction actuator rod-ends failed as a result of non-conforming 
threads. This condition, if not corrected, could lead to additional 
MLG undamped extensions, which may result in MLG structural failure, 
resulting in an unsafe asymmetric landing gear configuration.
    This [Canadian] AD mandates the replacement of the MLG 
retraction actuator rod-end subassemblies manufactured with non-
conforming threads with units that fully conform to the design 
requirements.

    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-
0331.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We considered the comment received. Air Line Pilots 
Association, International supported the NPRM.

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

    Bombardier, Inc., issued Service Bulletin 8-32-179, Revision A, 
dated March 9, 2017. This service information describes procedures for 
replacing the MLG retraction actuator rod-ends on both MLG assemblies 
with units that fully conform to the design requirements. 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 91 airplanes of U.S. registry.
    We estimate the following costs to comply with 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.
    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.

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.
