                AGENCY: Federal Aviation Administration (FAA), DOT.
                ACTION: Notice of proposed rulemaking (NPRM).
                -----------------------------------------------------------------------
                SUMMARY: We propose to adopt 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 proposed 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 proposed AD would 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 replacement of these parts would terminate the
                repetitive inspections. We are proposing this AD to address the unsafe
                condition on these products.
                DATES: We must receive comments on this proposed AD by March 25, 2019.

                Discussion
                 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.

                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 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.
                FAA's Determination
                 This product has been approved by the aviation authority of another
                country, and is approved for operation in the United States. Pursuant
                to our bilateral agreement with the State of Design Authority, we have
                been notified of the unsafe condition described in the MCAI and service
                information referenced above. We are proposing this AD because we
                evaluated all the relevant information and determined the unsafe
                condition described previously is likely to exist or develop on other
                products of the same type design.
                Proposed Requirements of This NPRM
                 This proposed AD would require accomplishing the actions specified
                in the service information described previously.
                Costs of Compliance
                 We estimate that this proposed AD affects 1 airplane of U.S.
                registry. We estimate the following costs to comply with this proposed
                AD:
                 Estimated Costs for Required Actions
                ----------------------------------------------------------------------------------------------------------------
                 Cost per Cost on U.S.
                 Labor cost Parts cost product operators
                ----------------------------------------------------------------------------------------------------------------
                66 work-hours x $85 per hour = $5,610........................ $16,456 $22,066 $22,066
                ----------------------------------------------------------------------------------------------------------------
                 We have received no definitive data that would enable us to provide
                cost estimates for the on-condition actions specified in this proposed
                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 proposed 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 proposed AD would not have federalism
                implications under Executive Order 13132. This proposed AD would 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 this proposed
                regulation:
                 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.

                The Proposed Amendment
                 Accordingly, under the authority delegated to me by the
                Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
                PART 39--AIRWORTHINESS DIRECTIVES
                0
                1. The authority citation for part 39 continues to read as follows:

                Sec. 39.13 [Amended]
                0
                2. The FAA amends Sec. 39.13 by adding the following new airworthiness
                directive (AD):
                Viking Air Limited (Type Certificate Previously Held by Bombardier,
                Inc.; Canadair Limited): Docket No. FAA-2018-1070; Product
                Identifier 2018-NM-154-AD.
                (a) Comments Due Date
                 We must receive comments by March 25, 2019.
                (b) Affected ADs
                 None.
                (c) Applicability
                 This AD applies to Viking Air Limited (Type Certificate
                previously held by Bombardier, Inc.; Canadair Limited) airplanes,
                certificated in any category, as identified in paragraphs (c)(1) and
                (c)(2) of this AD.
                 (1) Model CL-215-6B11 (CL-215T Variant) airplanes, serial
                numbers 1085, 1086, 1093, 1094, and 1098 through 1101 inclusive.

                [[Page 2793]]
                (d) Subject
                 Air Transport Association (ATA) of America Code 27, Flight
                controls.
                (e) Reason
                 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. 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.
                (f) Compliance
                 Comply with this AD within the compliance times specified,
                unless already done.
                (g) Inspection
                 Within 50 flight hours after the effective date of this AD:
                Accomplish a detailed visual inspection of the aileron control
                systems cables and flap interconnect system cables for disconnected
                or damaged cables in accordance with paragraph 2.A. of the
                Accomplishment Instructions of Bombardier Service Bulletin 215-3185,
                Revision 1, dated January 28, 2014; or Bombardier Service Bulletin
                215-4476, Revision 1, dated January 28, 2014; as applicable. Repeat
                the inspection thereafter at intervals not to exceed 50 flight
                hours.
                (h) Corrective Action
                 If any disconnected or damaged (including broken wires, unusual
                wear, or fraying) cables are found during any inspection required by
                paragraph (g) of this AD: Before further flight, obtain corrective
                actions approved by the Manager, New York ACO Branch, FAA; or
                Transport Canada Civil Aviation (TCCA); or Viking Air Limited's TCCA
                Design Approval Organization (DAO). If approved by the DAO, the
                approval must include the DAO-authorized signature. Accomplish the
                corrective actions within the compliance time specified therein. If
                no compliance time is specified in the corrective actions
                instructions, accomplish the corrective action before further
                flight.
                (i) Replacement
                 Within 29 months after the effective date of this AD: Replace
                the Teflon parts in the aileron control system, the aileron/rudder
                interconnect, and the aileron power unit beam in accordance with
                Parts A, B, and C of the Accomplishment Instructions of Bombardier
                Service Bulletin 215-3186, Revision 3, dated September 29, 2015; or
                Bombardier Service Bulletin 215-4477, Revision 2, dated September
                29, 2015.
                (j) Terminating Action for Inspections
                 Accomplishing the replacement required by paragraph (i) of this
                AD on an airplane constitutes terminating action for the inspections
                required by paragraph (g) of this AD for that airplane.
                (k) Credit for Previous Actions
                 This paragraph provides credit for actions required by paragraph
                (i) of this AD, if those actions were performed before the effective
                date of this AD using the service information specified in
                paragraphs (k)(1) through (k)(5) of this AD.
