Airworthiness Directives; Viking Air Limited Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for all 
Viking Air Limited Models DHC-2 Mk. I, DHC-2 Mk. II, and DHC-2 Mk. III 
airplanes that supersedes AD 2016-19-08. This AD results from mandatory 
continuing airworthiness information (MCAI) issued by the aviation 
authority of another country to identify and correct an unsafe 
condition on an aviation product. The MCAI describes the unsafe 
condition as corrosion of the elevator control rod and of the elevator 
actuating lever on the control column, which could cause these 
components to fail. We are issuing this AD to require actions to 
address the unsafe condition on these products.

DATES: This AD is effective December 22, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of October 24, 
2016 (81 FR 64053, September 19, 2016).

SUPPLEMENTARY INFORMATION: 

Discussion

    On September 8, 2016, we issued AD 2016-19-08, Amendment 39-18657 
(81 FR 64053, September 19, 2016) (``AD 2016-19-08''). That AD required 
actions intended to address an unsafe condition on all Viking Air 
Limited (Viking) Models DHC-2 Mk. I, DHC-2 Mk. II, and DHC-2 Mk. III 
airplanes and was based on mandatory continuing airworthiness 
information (MCAI) originated by an aviation authority of another 
country.
    There is a required action in AD 2016-19-08 to insert temporary 
revisions into the Airworthiness Limitations section of the FAA-
approved maintenance program (e.g., maintenance manual). These 
revisions incorporate repetitive inspections of the elevator control 
rod assemblies, the elevator actuating lever, and the control column 
torque tube for corrosion, cracks, and/or other damage.
    Viking Models DHC-2 Mk. I, DHC-2 Mk. II, and DHC-2 Mk. III 
airplanes are not certified under 14 CFR part 23--Airworthiness 
Standards: Normal, Utility, Acrobatic, and Commuter Category Airplanes 
and the associated FAA-approved maintenance program (e.g., maintenance 
manual) does not include an Airworthiness Limitations section. 
Therefore, the requirement in AD 2016-19-08 to insert Temporary 
Revision No.: 2-38, dated March 4, 2015, and Temporary Revision No.: 
2T-14, dated March 4, 2015, into the Airworthiness Limitations section 
of the applicable Viking Aircraft DHC-2 Maintenance Manual is not 
enforceable.

Relative Service Information Under 1 CFR Part 51

    We reviewed Viking Air Limited DHC-2 Beaver Service Bulletin 
Number: V2/0005, Revision `C', dated July 17, 2015. This service 
information describes procedures for doing detailed visual inspections 
of the elevator control rod assemblies, the elevator actuating lever on 
the control column, and the control column torque tube for corrosion, 
cracking, and/or other damage. This service bulletin also describes 
procedures for repairing or replacing damaged parts. 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 of this AD.

FAA's Determination and Requirements of This AD

    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 this State of Design Authority, they 
have notified us of the unsafe condition described in the MCAI and 
service information referenced above. We are issuing this AD because 
the way we addressed the actions in AD 2016-19-18 is unenforceable and 
the unsafe condition exists and is likely to exist or develop on other 
products of the same type design. The actions in this AD correct the 
unenforceability problem.

FAA's Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD. The FAA has found that the risk to the flying public justifies 
waiving notice and comment prior to adoption of this rule because we 
have already provided public notice on the intent of the actions in 
this AD. This AD only clarifies the repetitive inspection requirements 
of AD 2016-19-08 by correcting the means by which the repetitive 
inspections are done (in the AD versus maintenance manual). Therefore, 
we determined that notice and opportunity for public comment before 
issuing this AD are unnecessary.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not precede it by notice and opportunity for public 
comment. We invite you to send any written relevant data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include ``Docket No. FAA-2016-9527; Directorate 
Identifier 2016-CE-036'' at the beginning of your comments. We 
specifically invite comments on the overall regulatory, economic, 
environmental, and energy aspects of this AD. We will consider all 
comments received by the closing date and may amend this AD because of 
those comments.
    We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this AD.

Costs of Compliance

    We estimate that this AD will affect 135 products of U.S. registry. 
We also estimate that it will take about 11.5 work-hours per product to 
comply with the basic inspection requirements of this AD. The average 
labor rate is $85 per work-hour.
    Based on these figures, we estimate the cost of the basic 
inspection requirements of this AD on U.S. operators to be $131,962.50, 
or $977.50 per product.
    In addition, we estimate that any necessary follow-on actions will 
take about 8 work-hours and require parts costing $1,859, for a cost of 
$2,539 per product. Contact Viking Air Limited at the address 
identified in the ADDRESSES section of this AD for current pricing and 
lead time. We have no way of determining the number of products that 
may need these actions.
    There is no estimated cost of compliance difference between this AD 
and AD 2016-19-08 since there is no change in the number of affected 
airplanes or in the required actions.

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),

[[Page 93800]]

    (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.

2. The FAA amends Sec.  39.13 by removing Amendment 39-18657 (81 FR 
64053, September 19, 2016), and adding the following new AD:

2016-25-22 Viking Air Limited: Amendment 39-18748; Docket No. FAA-
2016-9527; Directorate Identifier 2016-CE-036-AD.

(a) Effective Date

    This airworthiness directive (AD) becomes effective December 22, 
2016.

(b) Affected ADs

    This AD replaces AD 2016-19-08, Amendment 39-18657 (81 FR 64053, 
September 19, 2016) (``AD 2016-19-08'').

(c) Applicability

    This AD applies to Viking Air Limited Models DHC-2 Mk. I, DHC-2 
Mk. II, and DHC-2 Mk. III airplanes, all serial numbers, 
certificated in any category.

(d) Subject

    Air Transport Association of America (ATA) Code 27: Flight 
Controls.

(e) Reason

    This AD was prompted by mandatory continuing airworthiness 
information (MCAI) originated by an aviation authority of another 
country to identify and correct an unsafe condition on an aviation 
product. The MCAI describes the unsafe condition as corrosion of the 
elevator control rod and of the elevator actuating lever on the 
control column. We are issuing this AD to detect and correct 
corrosion and/or cracking of the elevator control rod assemblies and 
the elevator actuating lever, which if not detected and corrected, 
could cause these components to fail. This failure could result in 
loss of control.

(f) Actions and Compliance

    Comply with this AD within the compliance times specified in 
paragraphs (g) through (m) of this AD, unless already done.

(g) Initial Inspections

    Within the next 120 days after October 24, 2016 (the effective 
date retained from AD 2016-19-08) or within the next 100 hours time-
in-service (TIS) after October 24, 2016 (the effective date retained 
from AD 2016-19-08), whichever occurs first, do the following 
inspections in accordance with section I. PLANNING INFORMATION, 
paragraph D. of Viking DHC-2 Beaver Service Bulletin Number: V2/
