39-19036; AD 2017-19-06]

Airworthiness Directives; Bombardier, Inc., Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Bombardier, Inc. Model CL-600-1A11 (CL-600), CL-600-2A12 (CL-601 
Variant), and CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604 Variants) 
airplanes. This AD was prompted by a new life limitation that has been 
introduced for the side brace fitting shaft and side brace-to-airplane 
fitting pin of the main landing gear (MLG). This AD requires revising 
the maintenance or inspection program. This AD also requires an 
inspection to identify the serial number, to serialize, and to record 
the accumulated life of the side brace fitting shaft of the MLG. We are 
issuing this AD to address the unsafe condition on these products.

DATES: This AD is effective October 27, 2017.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of October 27, 
2017.

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-600-1A11 (CL-600), CL-600-2A12 (CL-601 Variant), and CL-600-
2B16 (CL-601-3A, CL-601-3R, and CL-604 Variants) airplanes. The NPRM 
published in the Federal Register on June 7, 2017 (82 FR 26403) (``the 
NPRM'').
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2016-17R2, dated June 29, 2016 (referred to after this as the Mandatory 
Continuing Airworthiness Information, or ``the

[[Page 44310]]

MCAI''), to correct an unsafe condition for certain Bombardier, Inc., 
Model CL-600-1A11 (CL-600), CL-600-2A12 (CL-601 Variant), and CL-600-
2B16 (CL-601-3A, CL-601-3R, and CL-604 Variants) airplanes. The MCAI 
states:

    Based on in-service experience, a new life limitation has been 
introduced for the following side brace fitting shaft part numbers:
     600-10237-1/-5
     600-10237-3
     601R10237-1/-3
    In order to facilitate identification and tracking, the 
component must be identified and serialized. Bombardier has revised 
the Time Limits/Maintenance Checks (TLMC) Manual to include new life 
limits and issued Service Bulletins (SB) for serialization of the 
affected parts.
    The original version of this [Canadian] AD was issued to mandate 
the incorporation of the new TLMC life limits as well as 
identification and serialization of the affected parts. The revision 
1 of this [Canadian] AD was issued * * * June [10,] 2016 to correct 
a typographic error in Table A of the Corrective Actions section. 
The revision 2 of this [Canadian] AD is being issued to correct/
update the TLMC data in Table A of the Corrective Actions section.

    Required actions include an inspection to identify the serial 
number, to serialize, and to record the accumulated life of the side 
brace fitting shaft of the MLG. The unsafe condition is the loss of 
structural integrity of the affected part. 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-2017-0511.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM or on the determination of 
the cost to the public.

Conclusion

    We reviewed the relevant data 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.

    We have reviewed the following service information. This service 
information describes the life limits for the side brace fitting shaft 
and side brace-to-airplane fitting pin of the MLG. This service 
information is distinct since it applies to different airplane models 
in different configurations.

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.

[[Page 44311]]

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.

compliance (AMOC) in accordance with the procedures specified in 
paragraph (k)(1) of this AD.

(k) Other FAA AD Provisions

    The following provisions also apply to this AD:

(1) Alternative Methods of Compliance (AMOCs)
