Airworthiness Directives; Viking Air Limited (Type Certificate 
Previously Held by Bombardier, Inc.; Canadair Limited) Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Viking Air Limited Model CL-215-6B11 (CL-215T Variant) and CL-215-6B11 
(CL-415 Variant) airplanes. This AD was prompted by a report that a 
supplier fabricated Teflon parts with a charge of 15 percent fiberglass 
content instead of the specified 5 percent fiberglass content. This AD 
requires repetitive detailed visual inspections of the aileron control 
system cables and flap interconnect system cables for damage or 
disconnected cables, corrective actions if necessary, and replacement 
of the Teflon parts in the aileron control systems, aileron/rudder 
interconnect, and aileron power unit beam. The replacement of these 
parts terminates the repetitive inspections. We are issuing this AD to 
address the unsafe condition on these products.

DATES: This AD is effective June 13, 2019.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of June 13, 
2019.

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 Viking Air Limited 
Model CL-215-6B11 (CL-215T Variant) and CL-215-6B11 (CL-415 Variant) 
airplanes. The NPRM published in the Federal Register on February 8, 
2019 (84 FR 2791). The NPRM was prompted by a report that a supplier 
fabricated Teflon parts with a charge of 15 percent fiberglass content 
instead of the specified 5 percent fiberglass content. The NPRM 
proposed to require repetitive detailed visual inspections of the 
aileron control system cables and flap interconnect system cables for 
damage or disconnected cables, corrective actions if necessary, and 
replacement of the Teflon parts in the aileron control systems, 
aileron/rudder interconnect, and aileron power unit beam. The NPRM 
proposed that the replacement of these parts would terminate the 
repetitive inspections.
    We are issuing this AD to address parts manufactured with this 
higher percentage of fiberglass, which may cause deterioration of 
control cables and adjacent parts due to greater friction should they 
come into contact, which could lead to reduced controllability of the 
airplane.
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian AD CF-2018-27, dated October 
12, 2018 (referred to after this as the Mandatory Continuing 
Airworthiness Information, or ``the MCAI''), to correct an unsafe 
condition for certain Viking Air Limited Model CL-215-6B11 (CL-215T 
Variant) and CL-215-6B11 (CL-415 Variant) airplanes. The MCAI states:

    It was found that a supplier fabricated TeflonTM 
parts with a charge of 15% fiberglass content in lieu of the 
required 5%. Parts manufactured with this higher percentage of 
fiberglass may cause wear and rupture of control cables due to 
greater friction if contacted [which could lead to reduced 
controllability of the airplane].
    This [Canadian] AD mandates a [detailed] visual inspection of 
the aileron control system cables and flap interconnect system 
cables in the area of the aileron power control unit. The inspection 
is required to ensure that there is no cable damage or disconnect 
until the replacement of the TeflonTM parts has been 
completed in the aileron control system, the aileron/rudder 
interconnect and the aileron power unit beam. This [Canadian] AD 
also requires replacement of the TeflonTM parts.

    Signs of damage include broken wires, unusual wear, or fraying 
cables. 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-2018-1070.

Comments

    We gave the public the opportunity to participate in developing 
this final rule. 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 final rule as proposed, 
except for minor editorial changes. We have determined that these minor 
changes:
    <bullet> Are consistent with the intent that was proposed in the 
NPRM for addressing the unsafe condition; and
    <bullet> 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 Service Bulletin 215-3185, Revision 1, dated 
January 28, 2014; and Service Bulletin 215-4476, Revision 1, dated 
January 28, 2014. The service information describes procedures for a 
detailed visual inspection in the area of the aileron power control 
unit for damaged or disconnected aileron control system cables or flap 
interconnect system cables, and corrective actions. These documents are 
distinct since they apply to different airplane models in different 
configurations.
    Bombardier has also issued Service Bulletin 215-3186, Revision 3, 
dated September 29, 2015; and Service

[[Page 20247]]

Bulletin 215-4477, Revision 2, dated September 29, 2015. The service 
information describes procedures for replacement of Teflon parts in the 
aileron control system, the aileron/rudder interconnect, and the 
aileron power unit beam. These documents are distinct since they apply 
to different airplane models in different configurations.
    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 1 airplane of U.S. registry. We 
estimate the following costs to comply with this AD:

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.
    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.
